The Benefits of Metal Buildings

Metal Buildings

Oklahoma Metal Buildings are becoming more popular for a variety of uses. They are easy to erect, can be expanded and are highly customizable. They are also ecologically friendly and energy efficient.Metal Buildings

They can be insulated to save on heating and cooling expenses. This will help businesses reduce their energy costs.

Metal buildings are cost-effective solutions for a wide variety of construction projects. They can be used as workshops, storage facilities, or even as recreational areas. They are also durable and fully customizable to fit the needs of different users. However, it is important to consult with a fabrication team that offers superior quality control standards. This will ensure that your building meets all safety regulations and is built to last.

The costs of a steel building vary depending on your location and the size and design of the structure. Premade metal buildings are less expensive than custom-built options, but they may not be available in the exact dimensions you need. They are also more affordable than traditional wood-framed structures, which require a lot of labor to build.

Steel buildings are also a good choice for self-storage facilities. As American families grow, many people need more space to store their belongings. Unlike traditional storage buildings, metal buildings can be easily configured to create large indoor spaces for use by multiple tenants. They are also more resistant to pests and can withstand weather conditions.

Metal industrial buildings are ideal for wastewater treatment plants, electrical control rooms, guardhouses, well covers, pump shelters, and utility buildings. They are easy to maintain and offer excellent corrosion resistance. These structures are also more energy-efficient than other building materials and can be insulated to help save on heating and cooling costs.

Compared to a wood building, a metal building is more cost-effective because it does not require costly interior columns for support. This allows for a more spacious interior and provides flexibility to add partition walls as your business expands.

Another benefit of a metal building is that it can be assembled more quickly than a wood-framed structure. This can cut weeks off the building construction time and save on labor costs. Prefabricated kits are delivered to the construction site ready for assembly, which reduces the need for additional personnel and equipment. This means that you can start using your facility sooner and see a return on investment much faster.


Whether you’re building an office, workshop, or garage, durability is a crucial factor. You want to make sure that the structure you’re investing in can withstand harsh weather conditions, fire, and rodents. Metal buildings are renowned for their strength and resilience, making them an ideal option for any construction project.

The durability of metal buildings is a result of the high-grade materials that go into their construction. High-grade steel and specialized metal alloys provide superior resilience, resistance to damage, and other benefits.

This exceptional durability makes metal buildings one of the most cost-effective and reliable construction options available. They can withstand various environmental stressors, such as heavy winds, hail storms, snow loads, and seismic activities. They also offer more protection against pests and termites than traditional building materials, such as wood or concrete.

In addition to being durable, metal buildings are easy to customize and adapt to your specific needs. You can choose from a wide range of customization options, such as color, layout, and finishes. This versatility ensures that your steel building will perfectly align with your aesthetic preferences and functional requirements.

Moreover, a metal building can be designed to have wider clear spans, taller eaves, and longer building lengths, allowing it to accommodate large equipment and massive hanger doors. This ability to adapt to your unique needs and design specifications is an important feature of a metal building that sets it apart from other construction types.

Another benefit of a metal building is that it requires little maintenance. The exterior can be finished with a variety of different coatings, including strong steel panels, brick, stone, or tilt-up concrete. This means that you won’t have to worry about the need for regular repainting like you would with a wood structure. Furthermore, unlike wood, steel is termite- and rodent-resistant, eliminating the need for expensive treatments and inspections.

When choosing a contractor to construct your metal building, it is important to find out how much experience they have with the type of work you need them to complete. Ask for references from past clients and do your research online to determine if they are a good fit for you.

Ease of Maintenance

The durability of metal buildings makes them easy to maintain. They can withstand harsh weather conditions and natural disasters and last longer than buildings constructed of other materials. They are also a more cost-effective option for long-term use. They are available in a wide range of sizes and shapes, making them easy to customize for your specific needs. Additionally, you can add a variety of features, including insulation, doors and windows, and exterior finishes. You can also choose from different types of roofs, such as gable, single-slope, and curved.

A steel building is easier to maintain than a wood-framed structure, because the frame doesn’t need to be treated with pesticides to prevent termite damage. Moreover, steel is not prone to rot or warping. In addition, a metal building is more resistant to mold, mildew and fungus growth than other materials. This reduces maintenance costs by preventing the need to treat or replace the building’s interior.

In addition to reducing maintenance costs, the durable construction of a metal building can also lower insurance premiums. This is because insurance companies often offer better rates for steel buildings than other structures.

While a metal building is less expensive to build than traditional structures, it still requires regular maintenance. Preventative maintenance is essential to keep your building in top condition, and will extend its lifespan. To perform this maintenance, you should inspect the roof regularly for leaks and damage, clean the exterior, and check the HVAC system. In addition, you should seal any holes and cracks to prevent air leaks and water infiltration.

Another important step in maintenance is to wash the building with a cleaning solution every 3-4 months. This will remove the chalk-like dirt that can cause rust and mold growth. You should also trim the surrounding trees and shrubs to avoid moisture trapping in the building.

Pre-engineered metal buildings are built faster than other types of structures, as most of the work is completed in factories. This means they can be erected in half the time of other constructions. This fast build process translates to savings on labor and construction costs. It also allows for the flexibility of adding to a building as your business grows. Furthermore, these buildings feature clear-span framing that provides a column-free interior space. In addition to these advantages, pre-engineered metal buildings are also energy-efficient and environmentally friendly.


There are many customization options available with metal buildings, which make them a great option for unique construction projects. For example, you can choose from a wide range of roof styles and add windows and doors to your building. You can also customize the exterior color of your building to fit your aesthetic preferences. Additionally, you can choose from a variety of trim options, including different types of siding, wood paneling, and wainscoting.

Metal buildings are also more resilient to harsh weather conditions and natural disasters than other traditional building materials. They are fire-resistant, and are less likely to be damaged by insects or termites. Additionally, they are easier to maintain than other types of structures, and are more cost-effective than traditional building materials.

With customizable options, a steel building can be made to meet any business or industry’s needs. For example, a steel industrial structure can be used as a wastewater treatment facility, control room, guardhouse, or generator building. It can also be configured with environmental controls, making it ideal for recreational facilities such as skating rinks or swimming pools.

A steel building can also be used as a home office or workshop, and can be designed to include large openings and pre-punched holes for electrical and plumbing installation. In addition, the structure can be easily expanded in the future if additional space is needed.

Metal buildings can also be customized to accommodate specialized needs, such as mezzanines and partition walls. This flexibility makes them a smart choice for businesses that need extra storage or workspace. In addition, they can be built with a wide array of doors and windows and can be finished to match the existing look of your property.

Another option is to paint your building a color that matches your brand or business. You can choose from a variety of colors, from a bright emerald green to a cool blue. This will help your building stand out from the rest and make it easy to recognize. You can even go with a more subtle shade, such as white or charcoal.

An Operator’s Observations: Top 5 Video Episodes of The Dirt for 2021

2021 marked a new year for “The Dirt” and a new host.

Bryan Furnace began hosting the weekly videos in July, bringing his experience as an equipment operator to a broad range of topics for contractors and the construction industry as a whole.

From interviews to commentary, Bryan delivers his ground-level, straight-forward perspective to bear on everything from retaining employees to the infrastructure bill.

Here are Bryan’s top five Dirt videos from 2021, as determined by the most views on

(Want to make sure you don’t miss an episode of The Dirt? You can do so by subscribing to our Equipment World Daily Report newsletter or the Equipment World YouTube channel. We also post a new episode each week at 

1. How Does the Infrastructure Bill Affect Contractors?

In this episode of The Dirt, we give you all the important details of the $1 trillion infrastructure bill, which has since become law, and how it affects contractors. Bryan interviews Daniel Fisher, senior vice president at the Associated Equipment Distributors, to find out what’s in the massive legislation – and what’s not. Though this interview took place before the bill’s passage, the information on the legislation remains relevant. 

2. The Chip Shortage: How Did We Get Here?

The microchip shortage has been contributing to lower inventories for some equipment manufacturers. A variety of factors have coalesced into a perfect storm, creating a scarcity of chips. Long wait times for new chips are just the tip of the iceberg. Bryan breaks down the many reasons why it might be a long while before we see inventories balance out demand. 

3. Construction’s “Weird Disconnect” with Young Workers

The old-timers’ constant refrain that the younger generation doesn’t want to work meets an unspoken reality. Many high school graduates have never done real manual labor and have no idea what to expect on a jobsite. That, combined with construction’s tradition of yelling at workers who make mistakes, is leading many young workers to wrongly conclude they’re just not cut out for construction. So they quit. After spending time talking with young workers, Bryan embarks on a discussion on how the construction industry can bridge this “weird disconnect.” 

4. “No Call, No Show” Employees: Is This the New Normal?

Along with hosting The Dirt, Bryan is a part-time equipment operator who often fills in for employees who don’t show up for work. Not only are he and others throughout the construction industry seeing more no-shows, but there’s a growing trend of those workers not calling to let their employers know they’re going to be absent and when – or if – they’ll return. In this episode, Bryan discusses his observations of the problem – which appears to be more prevalent among worker 25 and under – and a possible solution.

5. Are You Playing ‘Musical Cabs’ With Your Operators?

Moving operators around frequently to different equipment can hurt contractors in the long run. Though it’s not always possible to keep an operator with the same machine all the time, the rewards for doing so as much as possible can mean big boosts for your two biggest assets: your employees and your equipment.

Reduce False Insurance Claims with These Cloud-Enabled Truck Cameras

A backup camera is always a good idea for cars and commercial vehicles. But multiple cameras – side, rear and interior – are even better. Samsara has developed a new product that connects all these camera feeds to the company’s Connected Operations Cloud. And with the Samsara system, you can use your existing cameras.

When combined with Samsara’s AI Dash Cams, customers gain 360-degree visibility in a single dashboard. This increased visibility combined with cloud connectivity allows managers to access video footage immediately and exonerate drivers from false claims. 

Cameras don’t lie

“We can now seamlessly integrate our existing cameras with Samsara’s platform, quickly retrieve video footage through the cloud in minutes, and significantly decrease our volume of backup incidents and associated payouts,” said Sajid Ordagic, safety manager at Rasmussen Group, an Iowa-based heavy construction company.

Trucking companies large and small can face a barrage of insurance claims and lawsuits, everything from backup incidents and sideswipes to major accidents. Without cameras proof of innocence is hard to come by. But, according to Ordagic, his company has seen a 30% reduction in backup incidents since installing Samsara Camera Connectors and expects to save $30,000 by exonerating drivers from false claims.

Coaching drivers

And cameras aren’t just for accident recording, they are also valuable in coaching drivers and improving their habits on the road. This means safety managers can leverage side, rear, and interior footage when coaching drivers, contributing to an enhanced experience because drivers can clearly see how their actions in the cab affect the area around the truck. 

Superior Plus Propane, a propane distributor serving 24 states across the U.S. with 2,300 trucks and more than 1,000 drivers, coaches its drivers with the Samsara system. “Having the Camera Connector will allow us to sit in our drivers’ seats and walk in their shoes. It will give us a much clearer picture of their exposure and the hazards they’re facing,” says Ryan Quiggle, director of health and safety.

Without the need to rip out and replace existing camera systems, customers using Camera Connector can also experience efficiency gains when it comes to installation. According to the company, the Samsara Camera Connector system can be installed in as little as 20 minutes, six times as faster than replacing all the old cameras.

Process More in Less Time with Cat’s New MH3026 Material Handler

An advanced electrohydraulic system for Cat’s new MH3026 material handler gives you a balance of power and efficiency to improve cycle times. The result is more material processed in less time, and that spells better ROI for waste and scrap metal applications.

A Cat C7.1 engine cranks out 128 horsepower and can operate on B20 biodiesel. The maintenance-free exhaust aftertreatment system maximizes uptime and lowers operating costs. Power and economy mode choices mean you only burn the amount of fuel needed to do the job, resulting in 10% lower fuel use compared to previous models, says the company.

Stronger swing torque

A new front linkage on the MH3026 reaches up to 42 feet 8 inches. The swing torque is 20% greater to move material faster. A heavy-lift mode gives you extra capacity when you need it, and Cat’s SmartBoom can travel up and down without using pump flow. This adds additional fuel efficiency and allows the operator to focus on grapple control for smoother operation.

For safety, Cat’s E-fence system comes standard and prevents the machine and attachment from moving outside parameters set by the operator in the cab. This can eliminate the possibility of hitting the cab with the attachment or running into adjacent structures in a tight work envelope. A pin code prevents unauthorized operation of the machine.

Multiple cameras

Large tempered glass windows with small pillars on the re-engineered cab protect the operator and enhance all-around visibility and operating safety. Standard right-side and rearview cameras, upgradable to 360-degree vision, display video feed on the large in-cab touchscreen monitor to further enhance work area visibility. Thicker impact-resistant windshields and roof windows meet EN356, P8B and P5A standards.

Another important safety feature, standard boom and stick lowering check valves, reverse oil flow in the event of an unexpected loss of hydraulic pressure keeping the front linkage secure in place. All daily maintenance points are quickly accessed from ground level, while a new service platform with steps provides safe and quick access to the upper service area. 

Easy access

For creature comforts, Cat is offering a choice between deluxe and premium designs. A joystick option eliminates the steering column and improves forward visibility, legroom and ease of entry. The left-hand console tilts up for exiting.

A 10-inch, high-resolution touchscreen monitor with jog dial offers easy navigation of the operator controls. Different machine operators can store their specific joystick and preferred power mode settings, and the machine automatically recalls the settings based on the operator ID. The cab sits tops out at 18 feet 10 inches to improve visibility for loading and material handling.

All engine filters and the new air-intake filter are coordinated to be changed at 1,000 hours. The hydraulic oil-filter change interval has been extended to 3,000 hours, and new anti-drain values keep hydraulic fluid clean during replacement.

Quick specs:

Engine: 128 horsepowerOperating Weight: 55,601-57,651 lbs.Maximum Travel Speed:16 mph

Yanmar’s First Electric Prototype: the SV17e Compact Excavator (Video)

Is it too soon to talk about Bauma, the big European equipment show held every three years in Munich?

We think not, especially when the previews demonstrate what is arguably the biggest and most significant trend in heavy equipment — electrification.

In this particular case, Yanmar gave the press a preshow preview of its first electric mini excavator prototype: the new SV17e. The company positions this machine as an important strategic step in the transformation for Yanmar Compact Equipment and indicative of the direction of the company.

“Our transformation will embrace our entire business and will encompass new products with alternative-fuel technologies,” says Giuliano Parodi, CEO of Yanmar. “The SV17e prototype is a demonstration of our intent to build a sustainable business for our customers and dealer partners.”

Without a diesel engine the overall size and weight of this excavator can be greatly reduced.YanmarThe SV17e mini excavator is aimed at customers in the European market and plays in the 1.5- to 2-metric-ton segment. It is powered by an electric drive with 48-volt batteries and fast charging capability. At zero emissions it not only passes the greenhouse gas test but is also quiet and suitable for indoor and confined-space operations where diesel exhaust emissions pose health hazards to workers.

“The operator is at the heart of this machine, and we have challenged ourselves to deliver the comfort, power, control and precision which we believe will surpass the expectations of professional operators,” says Cedric Durand, director product management.

In preparation for its sales start at Bauma 2022 (October 24 – 30), the prototype SV17e is currently undergoing a product testing regime including field tests.

If you don’t want to wait until Bauma to see the new SV17e in action, Yanmar Compact Equipment has prepared a short film. Watch the SV17e video here: 

And Yanmar isn’t alone in this race to electrification. Check out our other reporting on this topic at the links below:

Apprentices Help Build Their Own Training Facility – And Used the Latest Tech to Do It

In 2019, the Southern Nevada Operating Engineers was faced with a problem.

The Las Vegas community had exploded in size around the training facility it moved into in the mid-90s. The once prime location was no longer an ideal spot for heavy equipment training and operation.

It was time to move and rebuild for the future – and who better to do the rebuilding than the students and instructors themselves?

“Some of the apprentices we worked with onsite had never been in equipment before this project,” says Larry Hopkins, SNOE director of training. “They went from zero experience applicants to having the privilege of working alongside several instructors, coordinators and seasoned tradespeople to make this facility come to life.”

The new 28,000-square-foot center sits on nearly 100 acres and features state-of-the-art training rooms, classrooms, a machine shop, welding stations, and grounds to move dirt and simulate projects.

“It was a very proud moment to see it start from bare dirt and rock to what we have now,” says Chris Trolson, SNOE assistant director of training. “It’s fulfilling to see our students go out there and take ownership of this. You could feel the pride because they can see what they accomplished.”

Southern Nevada Operating Engineers JATCStudents assisted with everything from grading the site to paving the parking lot, and they used the latest technology to do it. Under the guidance of operating engineers and instructors, SNOE students used full 3D Trimble Earthworks automatics on an excavator and on a mastless dozer, as well as Trimble Siteworks and WorkManager to facilitate the data.

And for many of the students, the technology was second nature. “Our students just out of high school or their early 20s are much less afraid of the technology than those of us who have been around for 35 or 40 years,” says Hopkins. “They have an advantage growing into this technology. They’re excited about it.”

Education embedded with technology

In addition to the technology used to build the facility, tech is embedded in almost every aspect of the training programs and classrooms.

Twelve 25-square-foot classrooms are equipped with 4K smart boards, cameras and AV for interactive learning and guest speakers. The boards are also a good starting point for familiarizing students with machine displays. “Instead of trying to crowd 10 to 12 kids around a cab, we can show them Trimble emulators on the board,” says Trolson. “You see the a-ha moments once they get into the field. They build off that experience.”

In addition, simulators acquaint students with the equipment before turning them out in the field. “You’ll have 500 bad passes before you get a good pass on a piece of equipment,” says Trolson. “With simulators, we can get rid of a lot of that before we go out in the field. It helps build that confidence so they know they can do it.” The trainers plan to add virtual reality simulators down the road for an even more immersive experience.

Students in the heavy-duty repair program are also engaged in technology from day one. “They have to be familiar with the computer technology that is running the heavy equipment and how to troubleshoot it,” says Hopkins. “I’m not exaggerating when I say there are 200 to 300 different kinds of systems and menus on these different makes and models of equipment. It can be a nightmare. That technological training is wrapped into everything we do.”

Southern Nevada Operating Engineers JATC under construction.
Southern Nevada Operating Engineers JATCBuilding a labor force

Since opening its doors in July, the instructors have already trained several classes of operators and technicians. In an industry desperately seeking workers, the trainers say there is a lot to be optimistic about.

“Work is starting to pick up and my phone has been ringing off the hook,” says Trolson. “We have a lot of applicants we’re going to be putting in the field. Our regular classes are always full.”

“We’re not having issues recruiting,” added Hopkins. “Contractors just need to give us a call, and we’ll provide the people they need.”

The facility routinely has 125-150 apprentices training at any one time, primarily from the four surrounding counties in southern Nevada. The trainers have seen an uptick in women and minorities entering the program in recent years as well.

And as for graduates, the market is good. “Every one of those apprentices who helped with the facility construction has not been out of work since,” says Hopkins. “They went from working on this project straight to contractors and are still going today.”

Once those new recruits hit your jobsite, the education doesn’t stop. Trolson’s best advice for mentoring new employees: patience. “Teach them. Bring them along. You’re investing into the future with this person. You have to put the time and effort into it to get the payback.”

The Southern Nevada Operating Engineers JATC will be used as the new live demonstration and operating site for Trimble Dimensions, held November 7-9, 2022.

Doosan Launches New Lineup of Compact Excavators for U.S.

Doosan Infracore North America is breaking the final ties with former sister company Doosan Bobcat with a new line of compact excavators for the U.S. in 2022.

Four models, ranging from 2.7 to 5.5 tons, will arrive in the first quarter after being produced in South Korea, where Doosan is based. The models will replace Bobcat-made compact excavators, as well as break new ground in the U.S. for Doosan Infracore. (Videos of the new compact models in action are posted at the end of this story.)

More sizes are planned, including a 4-ton model next fall and 1.7- and 1.9-ton models in 2023. The company’s 6- and 8-ton excavators will be upgraded next year as well. And an electric compact excavator shown last year as a prototype at ConExpo will be hitting the market in mid-2023, according to Aaron Kleingartner, Doosan product and dealer market manager.

Within two years, the entire Doosan-built excavator lineup in the U.S. will extend from 1.7 to 100 tons, Kleingartner said.

Compact excavators unveiled

Doosan rolled out three of its new -7 compact excavators – the DX27Z-7, DX35Z-7 and DX50Z-7 – at a recent media event at the company’s testing grounds in Tucson, Arizona.

The displayed machines were all zero tail swing. A DX55R-7 model is also due out next year that will be reduced tail swing. Conventional tail swing versions will be available as well, the company says.

Features include full glass door and metal frame on the cab exterior for operator visibility, a powerful heating and air system, and Bluetooth radio, Kleingartner said. The excavators are also available with an open, instead of enclosed, cab.

For the first time, DoosanConnect telematics will come standard on the machines. Steve Americano, product manager for mini excavators, said the system includes geofencing that will send an alert if the machine moves outside of the geofence’s radius, which can be set by the owner.

The compact excavators have a new operator platform that insulates the cab from engine heat, Americano said. An auto-shift function automatically shifts engine speed depending on the terrain. All engines are Doosan.

The standard arm for the excavators is 43 inches. An optional 51-inch arm is available.

Hydraulic flow can be adjusted from the cab to handle various attachments. The machines come equipped with connectors needed for a hydraulic quick coupler.

Options include a rearview camera, LED lights and additional counterweight for handling heavier attachments.

These machines come with a one-year, 1,500-hour warranty. There is also a three-year, 5,000-hour powertrain warranty that “covers pumps, motors, all the high dollar components,” Americano said.

Phasing in Doosan-built excavators

Doosan Infracore was sold by parent company Doosan Heavy Industries & Construction to fellow South Korean company Hyundai Construction Equipment earlier this year. Doosan Infracore and Doosan Bobcat have supplied excavators to each other through a dual-brand agreement.

Bobcat provided 3-, 4- and 5-ton excavators that were branded Doosan, and Doosan provided Bobcat with 14- and 17-ton excavators that were branded Bobcat, according to Doosan CEO Edward Song.

Bobcat was not part of the Hyundai purchase and remains under the Doosan Heavy umbrella. Doosan Infracore is now part of the newly created Hyundai Genuine subsidiary along with Hyundai Construction Equipment.

After the new Doosan compact excavators come out, only a 4-ton model will be a Bobcat machine. Song said that the 4-ton model will also be replaced in the third quarter of 2022 with a Doosan-built excavator. Song noted that Doosan has the capability and experience with excavators under 5 tons in Korea and in European markets.

The move toward Doosan-branded compact excavators for the U.S. began in 2018 when Doosan Infracore North America and Doosan Bobcat separated their businesses, Song said. Doosan Infracore plans to capture some of the growing compact excavator market, as well as give its dealers a broader range of equipment.

“We will be bringing those machines in from our design teams in our factories in Korea next year,” said Kleingartner. “They are completely Doosan designed and manufactured.”

Is Construction Ready for Electric Heavy Trucks?

When discussing new technology for heavy trucks – Classes 6, 7 and 8 – we have to start with electrification.

It’s been the biggest buzz in recent years.

Several OEMs have demo’ed electric models, providing a proof of concept. But it’s clear not every application is suited to electric trucks, especially when it comes to construction.

Three criteria are used to determine whether an electric truck is the right choice for the task:

One, the loss of payload capacity due to battery mass is not a deal breaker.

Two, the trucks are not in motion for the entire workday, requiring additional charging.

Three, they come home at night. This is based partly on the need to charge, and until charging stations become as common as gas stations, most electric trucks will need to return home for that process.

But even charging stations on every corner won’t answer the second part of the home-at-night requirement, which is that charging massive vehicle batteries takes time. It’s not something that can be completed while the driver is inside Pilot Flying J having lunch.

The application most often cited as a perfect match for electric vehicles is pickup and delivery (P&D).

In construction, good matches could include service, fuel and water trucks, and trucks shuttling equipment between sites, whether on a flatbed or a trailer. But dump trucks, mixers and a number of other mainstay applications would not be a great place to go electric.

Here’s a look at the latest heavy trucks on the market, advancements in truck electrification and a lot of other technology that can help drivers and contractors:

Who’s gone electric?

Kenworth’s T680E has a range of up to 150 miles, depending on the application, and can be fully charged in 3 hours.

This Class 8 truck (pictured at the top of this story) uses Meritor’s Blue Horizon 14Xe tandem electric powertrain that provides 536 horsepower of continuous power and up to 670 horsepower peak power and 1,623 pound-feet of torque. Top speed is 70 mph. Two gross vehicle weight ratings (GVWR) are offered: 54,000 and 82,000 pounds.

Kenworth says the T680E is targeted at the P&D, regional haul and drayage markets. It also offers two electric low-cab-forward models, the Class 6 K270E and Class 7 K370E.

Electric motors are the HV2600 and HV3500, rated at 355 and 469 horsepower, respectively. With the HV3500, the truck can maintain 40 mph on a 6% uphill grade. Range is up to 200 miles and top speed is 65 mph.

Equivalent models from Kenworth’s sister company, Paccar, are the Peterbilt 579E and the 220EV.

Mack offers the LR Electric, its first – and so far, only – fully electric truck. But it’s only offered as a refuse truck. Tim Wrinkle, Mack Trucks construction product manager, explains why:

“Refuse made the most sense. It is a closed-loop application where the vehicle returns to its home base each day, allowing it to be charged.”

Is construction ready for electric trucks?

Despite all the electric hype and buzz, construction customers seeking electric vocational trucks are left with few, if any, options.

Construction will be one of the last markets to go electric,” says David Hillman, senior director of vocational marketing, Navistar. Navistar produces International brand commercial trucks. “It will get there eventually, but not soon.”

Engine options for the International HX620 are the International A26 with up to 500 horsepower and 1,750 pound-feet of torque, or the Cummins X15 with up to 605 horsepower and 2,050 pound-feet of torque. Transmission options include an Allison automatic, Eaton manual or Eaton automated manual. The HX620 has traction control, electronic stability control and Bendix Wingman Fusion. Single and dual fuel tanks are available up to 240 total gallons.Navistar InternationalHe says construction tends to be local, and a large number of construction trucks come home each night, which meets two of the necessary criteria for making electric work.

Beyond that, Hillman says, construction would benefit from characteristics of electric vehicles, especially immediate torque and low noise.

As with electric passenger vehicles, initial costs tend to be higher than for traditional internal-combustion vehicles, but operating costs can be competitive. Oil and filter changes are eliminated. Foundation brake wear can be significantly reduced, especially for trucks equipped with regenerative braking.

Battery weight remains a consideration, “but since we introduced our eStar truck in 2010, battery technology has advanced significantly, and part of that advance is a dramatic reduction in battery weight,” Hillman says.

His advice to customers considering electric trucks is to work with the dealer as a consultant. Understand that vocational applications are wildly diverse, and the dealer can help identify which of your applications would be best suited for electric.

But mostly, “manage your fleet as you always have. Understand your operation and the impact of fleet management decisions. Hold the OEM and the dealer accountable to make sure they keep your best interests in mind.”

Regulations driving change

California is the major mover in bringing electric vehicles into use, and Brian Tabel, executive director of marketing of Isuzu Commercial Trucks of America, says the company probably will not roll out electric models until late 2023 or early 2024.

The California Air Resources Board (CARB) mandate has not been finalized but will almost certainly require that a certain percentage of vehicles be “zero emissions.” He says other states may follow suit. Pennsylvania seems likely to do so. States will have the option of following EPA or CARB requirements.

“Electrification is here, and we’re fully aware of that,” Tabel says. “We’re engaged in development and testing right now but are still a year or a year-and-a-half away from providing details.”

Isuzu FTR Class 6 truck
The Class 6 Isuzu FTR has a GVWR of 25,950 pounds and a GCWR of 30,000 pounds. Power comes from a Cummins B6.7L diesel engine rated at 260 horsepower and 660 pound-feet of torque. That output is run through an Allison 2500 RDS six-speed automatic transmission. The FTR will accept bodies up to 30 feet long. Full air dual-circuit brakes with ABS and 16.5-inch S-cam drums front and rear provide stopping power. Fuel tank choices are 50 or 100 gallons.IsuzuTabel says one market where it seems electric vehicles would be shoo-ins is landscaping. “Landscapers meet the general requirements for using electric trucks efficiently, but that market has also been adopting electrification strongly, from string trimmers to mowers to chain saws. Some landscapers even have solar panels on the roofs of their trucks to provide equipment recharging between jobs.”

Landscapers are also acquiring bigger trucks to do bigger jobs. Many still rely on one-ton duallies but more are moving into low-cab-forward models such as the Class 6 Isuzu FTR and Class 7 FVR. The nimble handling of these trucks with their short bumper-to-back-of-cab distances and tight turning radiuses, plus the fact they can be upfitted with everything from cargo boxes to stakesides and flatbeds, make them very appealing.

Technology improving safety

Hillman says that among the many other technological advances in trucking, collision mitigation is often at the front. Cameras are also important, including those that capture in-cab video. Hillman says there’s a cultural bias to assume the truck driver is at fault in a multi-vehicle collision, “and in-cab video can demonstrate that the driver was operating the truck in a safe and responsible manner.”

Some drivers see in-cab video as an unwelcome intrusion of Big Brother, “but that typically only lasts 60 days or until the first time their safe operation of the truck is called into question.”

Hillman points to the suite of safety tools provided by Navistar’s International Diamond Logic package. Many features can be programmed by the customer.

For example, vehicle speed can be limited when moving with the body out of stow position. In reverse, the radio can be muted to reduce distraction. Camera point-of-view can be integrated with turn-signal activation to provide better visibility when turning or changing lanes.

Hillman says one technology that does not receive enough attention is the ability of the truck to be connected to the dealer, to the customer and to other vehicles and equipment on the jobsite.

Tabel says Isuzu’s optional advanced driver assist system (ADAS) will debut on its 2022 interim N-Series diesel models before being deployed on the 2023 N-Series gas and F-Series models. Features include lane-departure alerts and automatic braking for collision avoidance. All F-Series trucks now have the Cummins B6.7L engine.

Mack granite truck Bendix Wingman Fusion
Mack Granite trucks are available with the next generation of Bendix Wingman Fusion, a camera- and radar-based driving assistance solution.Mack TrucksMack’s optional ADAS is the latest generation of Bendix Wingman Fusion. Mack Command Steer for the Granite axle-back model uses an electric motor to complement the steering’s hydraulics. Steering effort is reduced by up to 85% and helps the driver maintain a consistent course in strong winds, on rough roads and in other challenging conditions.

Keeping electronic systems current requires updates, and Mack Over the Air (OTA) remote programming allows drivers to perform updates through the truck’s instrument cluster at whatever time is most convenient.

Standard on Anthem and Pinnacle tractors and Granite construction models, “driver-activated OTA updates can be done in minutes without a visit to the dealer to receive software updates and set vehicle parameters,” says Wrinkle.

Assist technologies available on the Kenworth T680 Next Gen include lane-departure warning and Lane Keeping Assist. Lane departure uses an audible alert while Lane Keeping Assist provides a tactile alert through the steering wheel.

The T689 is also available with adaptive cruise control that monitors traffic conditions and modulates throttle and brake positions to maintain a pre-set following distance to the vehicle ahead.

Kenworth’s Side Object Detection continuously monitors the passenger side of the truck and provides audible and visual alerts when an object or vehicle has entered certain zones.

Covid lingers

Covid is still playing a major role in the trucking world.

“Economic strength has continued despite ongoing Covid disruptions,” says Jonathan Randall, Mack Truck senior vice president of sales and commercial operations. Consumer spending and residential construction have contributed to robust customer demand, increasing lead times and order backlogs.

However, there’s a bottleneck of goods at ports, and although freight pricing is expected to remain high, carriers are having trouble recruiting drivers to expand their fleets.

Hillman says everyone needs to be prepared for ongoing delays of parts and products. Microchip availability is one example. Navistar, like everyone else, is having hiring challenges. His advice: “Try to adapt as best you can in an ambiguous environment.”

Tabel says lead times have gone from two months in pre-Covid days to nine to 12 months now. Chassis lead times are long. Body lead times are also long, and costs vary frequently, sometimes day-by-day.

“Everything is in demand, and everything is in short supply,” he says. “It’s just the way things are for the time being.” 

Volvo VNR 400 truck
The Volvo VNR 400 has a 42-inch flat-roof sleeper to maintain hours of service on short hauls. Engine options are a Volvo D11 with up to 425 horsepower and 1,550 pound-feet of torque, or a Volvo D13 with up to 500 horsepower and 1,850 pound-feet. Transmission options are Eaton Fuller manuals of 10-, 13- or 18-speed; or Volvo I-Shift 12-speed, I-Shift 12-speed severe duty or I-Shift 13- or 14-speed with crawler.Volvo
