EDITOR’S NOTE

Mining Industry Gearing up for MINExpo 2021

O

S. JENSEN

nce every 4 years, one of the world’s largest mining industry events comes to Las Vegas—MINExpo International®. This event is a giant not only in regards to the amount of exhibit space it features but also the equipment on display.

MINExpo has always been a favorite of the OEM Off-Highway staff because we get to see, and sometimes even climb around on, some of the biggest off-road equipment in the world. Coming face to face with a two-story mining dump truck definitely gives some perspective on things...as does a convention center filled with similarly large equipment and components.

And like many of the off-highway equipment industries we cover, mining is one in which an array of advanced technology is being implemented and researched. Autonomous equipment, for instance, has been in use at mine sites around the world for over a decade now. Electrification efforts are also increasing to help keep operators At MINExpo, there’s lots of fun to be had comparing your height to safe, especially in underground mining applications. that of the equipment.

While MINExpo had to be pushed in 2020 due to the pandemic, organizers are ready to hold the event this year, and they’re anticipating it will be as big as ever. Over 675,000 sq. ft. (62,709.6 sq. m) and 11 halls of the Las Vegas Convention Center will be filled with mining equipment and technology.

Several manufacturers—over 1,200 suppliers say show organizers—are currently scheduled to exhibit at the show, demonstrating the industry’s readiness to get back to in-person trade shows. Starting on pg. 34, you can read about the new equipment and technology scheduled to be introduced at the show. And be sure to visit our dedicated MINExpo channel at www.oemoffhighway.com/minexpo-2021 to stay up to date on news throughout and after the show, as well as mining-related content.

And if you’re attending the show, be sure to stop by our booth in South Hall #26242.

SLOWER GROWTH ON HORIZON FOR INDUSTRIAL AND CONSTRUCTION MARKETS

L

eading indicators in the U.S. and Europe are beginning to decline, indicating growth in the industrial sector will begin to slow by early 2022. Machinery orders in the agricultural and construction equipment markets were up from 2020 through May; however, slowing growth is likely in 2022 for the construction equipment market due to declining leading indicators.

Europe Agricultural and Forestry Machinery Production was also up through May from 1 year ago, and is expected to continue rising in the near term. Germany Industrial Production is up, but may be hindered in the near-term due to recent flooding.

Autonomous Vehicles Create More Intuitive, Easier to Use OPERATOR INTERFACES

Increased automation will simplify, and eventually minimize the need for operator cabs and controls.

by Sara Jensen

A

utomation is impacting many aspects of heavy-duty vehicles and equipment, including the operator cab.

Operator interface components—also referred to as HMI (human machine interface)—in particular are evolving to meet the needs of automated systems and vehicles.

According to John Pannone, Vice President of HMI Systems, EAO, a lot of equipment today is adopting dual roles in which there are autonomous and manual features, also referred to as conditional autonomy. This requires the equipment and its components to be able to easily shift from one mode of operation to the other.

Pannone says this shift in how machines operate both adds and takes away some features within the operator cab. It also makes some features more important.

Jay Iyengar, Chief Technology Officer, CNH Industrial, says in the off-highway equip-

ment industry autonomous operation is more complex than on-road vehicles.

In addition to going from point A to point B, the machine also needs to do active work like planting or seeding.

“The user interface gets a little complex because it is also being used to control the equipment to do the work while it’s actually moving,” she explains.

Machine operations are still complex but as automation progresses, they will become less so. And this will apply to the operator interface as well. Instead of pushing 10 buttons or settings, it will be necessary to use just one or two as most of the work will be done in the background by the automation system says Iyengar. It will help to make things more intuitive and user friendly.

This will be particularly important as younger generations enter the market who don’t have the skills or experience of those leaving it. Making equipment easier to use will help speed up the training process while also increasing operators’ comfort and productivity.

The ultimate goal of automation is to help increase productivity, simplify decision making for operators and eventually reduce operational costs.

Adaptability and differentiation will be key Pannone agrees there is a greater need for intuitive operation for HMI designs, particularly those that provide autonomous and manual modes. This equates to there being more feedback so machine operators can be sure they’re controlling the piece of equipment in a safe manner.

“There’s a great need to understand what mode the equipment is in, so we find that there’s a lot of visual [or] audible indication,” says Pannone. “But to have HMI products and components that are adaptable is really something that we’re seeing customers appreciating because if products can be utilized in both modes, or if you have products that can support the features of both modes, that’s really helpful.”

HMI which can easily be adapted or modified for autonomous and manual operation can help ease the design process for OEMs as they could potentially use the same components for each operating mode. When in autonomous mode, the interface components may need to be used for Removal of the operator cab on Case IH’s concept autonomous tractor enabled a reimagining of the overall machine design and styling.

indication purposes whereas manual mode will require more interaction from the operator and the components need to provide both capabilities.

Pannone says many of EAO’s products include illumination capabilities which can help with this.

He says the company is also developing products which are CAN and LIN based—both serial communication protocols prevalent in today’s heavy-duty equipment and especially that which utilizes automation in some manner. “These are serial interface controls that allow for greater visual, audible and flexible designs,” he says.

Offering products in various shapes, sizes and colors allows OEMs to better differentiate their control panels for easier operation, as well. For instance, a large, red button may be used for an emergency stop; red is commonly associated with emergencies or stopping so making a button this color helps provide more intuitive operation.

Helping operators quickly and easily differentiate which interface components do which machine functions not only improves productivity, but safety, as well. The level of automation built into a machine will determine how much an operator needs to interact with it, and thus how involved they will be in ensuring safety on the work site.

Related to this, Pannone says there will be a greater need for components which comply with Functional Safety standards (ISO 26262). Essentially, the standard is meant to ensure the safety of electrical and electronic systems and components.

Pannone says EAO is currently developing products which meet this standard, such as the company’s Series 09 CAN-based solution. Whether the HMI products are incorporated into a piece of equipment or on a remote control used to autonomously operate a machine from a distance, ensuring they are ISO 26262 compliant assures all parties involved that a safe working environment is maintained.

New cab and interface options Although operator cabs have become more simplified in recent years, there are still a lot of physical buttons and displays with which machine operators need to interact. However,

increasing levels of automation may bring more control outside of the cab to a tablet or other disconnected device, says Iyengar.

There are already some examples of this in which an operator can autonomously control a piece of equipment from a distance using a tablet, pendant or operator’s station. The pendent and operator’s station will still utilize some HMI similar to that currently found in the cab such as joysticks and buttons.

But eventually, as fully autonomous vehicles become more prevalent, there will likely be a removal of the operator cab and thus a diminished need for HMI products. Some small amount of HMI will be necessary on

the machines, says Iyengar, as there will still need to be physical interaction with the machine in case connectivity is lost or information needs to be downloaded from it.

In the distant future she says HMI could potentially be removed completely, but in the near-term operator interface solutions will remain an important component of an overall machine design. Removal of the operator cab though will provide both OEMs and component suppliers—including HMI manufacturers—the opportunity to rethink their designs.

“If you don’t have the cab, it gives you a lot more degrees of freedom in how you design the overall machine,” says Iyengar. You can essentially do a ground up design and create new vehicle architectures that may or may not look like the equipment many customers are used to seeing today.

For instance, Raven Industries— which CNH Industrial announced it would be acquiring in June—has been developing autonomous systems for agricultural equipment for several years. Its OMNiPOWER solution (formerly known as DOT) is a self-propelled power platform which allows easy interchange of farm implements such as sprayers or spreaders. No operator is required, which lead Raven to create a machine with no operator cab and a more simplified design.

As Iyengar describes it, the machine has a galley style and does not look anything like a tractor or other

piece of equipment one might see in farm fields today. Removal of the cab allowed Raven to create this unique design which aims to help farmers improve their productivity and efficiency.

As it is a single platform on which different attachments can automatically be attached, it can be used for various tasks throughout the farming season.

This could potentially help reduce the amount of equipment farmers need, further aiding their productivity as well as cost savings potential.

Autonomous vehicles are a key development area for CNH Industrial. In 2016, CNH’s Case IH brand premiered an autonomous concept vehicle, a cabless row crop tractor capable of fully autonomous operation with various field implements. The machine was based on a Case IH Magnum tractor but with reimagined styling, which removal of the operator cab enabled.

Since then, the company and its various brands have continued to research and develop autonomous vehicles and systems, knowing autonomy will only continue to become more vital to help improve safety and productivity, as well as overcome the labor shortages challenging many off-highway equipment industries.

Removal of the operator cab will of course impact many components and

systems currently used on heavy-duty equipment like HMI and air conditioning systems. Iyengar says this will significantly simplify machine designs, but also require use of very robust technology to ensure a properly functioning machine.

She says there is a tremendous amount of sophisticated technology already being utilized in the agricultural and other off-highway equipment industries. Technology will continue advancing, especially as automation progresses, and how it is deployed is just as important as its actual development. It will be vital for manufacturers to ensure technology is deployed in a manner which adds value to customers.

How technology and heavy equipment designs evolve in the coming years remains to be seen. Iyengar says she believes there is a big transformation coming in the next 4-5 years with the deployment of more autonomous vehicles with Level 3 and 4 capabilities.

LAWN AND GARDEN EQUIPMENT

MILLION UNITS

Sales of lawn and garden equipment are trending well in 2021, and expected to remain positive into the coming year. contributed by Jim Downey, Vice President-Global Data Products, Power Systems Research SALES PROJECTIONS

U

nit sales of lawn and garden equipment in the United States are thriving right now and will make 2021 a very nice year for the market. The products included in this article are: • Commercial Walk-Behind Mowers,

• • • • • • •

Zero-Turn Mowers, Walk-Behind Rotary Mowers, Snowblowers, Lawn and Garden Tractors, Chainsaws, Edgers, Hedge Cutters,

• Leaf Blowers, • Leaf Vacs and • Trimmers.

These products are split into two categories: mowers/snowblowers and handheld equipment. This is a very large market in terms of the sales volumes sold in the United States each year, and this market is growing.

Sales projections for 2021 are edging towards 16 million units, with handheld equipment accounting for almost 60% of that number. With more people working from home because of COVID-19, the need by consumers for more equipment has boosted the sales increases.

The other interesting aspect when looking at this market is how much of the product is electric (either battery or corded) and what is changing about the adoption from internal combustion (IC) products to electric units.

More disposable income and time at home over the past year has lead to increased sales of lawn and garden equipment.

Mowers and snowblowers The mower and snowblower products within the lawn and garden equipment market in the United States include commercial walk-behind mowers, zero-turn mowers, lawn and garden tractors, walk-behind rotary mowers (consumer) and snowblowers.

Adoption rates toward electric drives for the riding mowers and commercial mowers are less than Power Systems JOHN DEERE

Current State of the U.S. Lawn & Garden Equipment Market

Zero-turn mowers are popular among residential and commercial customers, which will drive market growth through 2022.

EXMARK

Research (PSR) is projecting for handheld products.

Commercial walk-behind mowers Commercial walk-behind mowers (heavy-duty hydrostatic drive) are seldom used for residential applications. These mowers are expected to see a sales increase of about 7.5% for 2021. Sales growth will start to level off around 2023 and 2024. The main players are Scag, DR, John Deere, Ferris, Gravely, Exmark and Hustler.

Mean Green Mowers is currently making an electric commercial walk-behind mower, but that market has not really taken hold yet.

Zero-turn mowers Zero-turn mowers are very popular among homeowners for residential use and contractors for commercial duty. These are riding lawn mowers that have a turning radius of zero when the two wheels rotate in the opposite direction. Some of the leading brands sold in the United States are Bad Boy, Cub Cadet, John Deere, Toro and Kubota.

Electric models are not as popular at this point, and PSR is projecting only 25% of the market to be non-IC by 2026. The main electric players currently are Ryobi, EGO and Mean Green Mowers. This total market is expected to increase by close to 9% this year and another 7-8% in 2022.

Lawn and garden tractors Lawn and garden tractor sales for 2021 should be 6-7% higher than the amount sold in 2020. These riding lawn mowers are versatile and give home-

owners many options/attachments to complete other tasks as well. Lawn and garden tractors are rarely used for commercial work.

This product has the largest volumes for all the riding lawn mowers. Again, the adoption of electric drive types has been slow to this point. The main brands include Husqvarna, John Deere, Cub Cadet and Craftsman.

Walk-behind rotary mower Walk-behind rotary mowers are push-behind lawn mowers with a rotary cutting blade which rotates around the center. Sales in the U.S. this year should increase to over 5 million units. Another increase of about 4-5% in the sale of lawn mowers is expected for next year.

Some of the common brands sold are Toro, Honda, Craftsman, Troy-Bilt, EGO, Greenworks and Ryobi. Currently gasoline mowers account for 80% of the market. PSR is anticipating the

share for electric lawn mowers to be close to 45-50% of the market by 2026.

As with most of these products discussed in this report, people have invested in their lawn and garden equipment over the last 18 months as they have spent more time with their lawn and gardens during the pandemic.

Snowblowers The sale of snowblowers is very much related to weather and is seasonal for the most part. Ariens is the market leader without any electric models yet.

Following Ariens, other brands include Toro, Snow Joe, Troy-Bilt, Simplicity and Husqvarna. Snowblower sales are expected to increase 8-9% over 2020.

PSR is projecting the market to be 60% electric drive by 2026.

Handheld equipment market PSR is projecting the handheld equipment segment to increase by 9% this year from 2020. It also anticipates this market will continue to grow by over 12% during the 2-year span 20212023. Much of this growth is consumer driven.

Chainsaws Chainsaws make up the largest sales volume in the handheld equipment category. The market is now over 3 mil-

20

lion units. PSR is projecting this product to grow 9% from 2020-2021. Some of the main players in the chainsaw space include STIHL, Poulan/Poulan Pro, Echo, Husqvarna and Ryobi.

The market right now for chainsaws is evenly split between IC and electric (51% versus 49%). By 2026, PSR is projecting that electric chainsaws will be over 70% of the units sold in the United States.

Edgers The edger market is growing by 8% this year. Edgers are used to trim/ cut boundaries between a lawn and streets, driveways, paths or gardens.

The main brands for lawn edgers are STIHL, Greenworks, Black+Decker, TroyBilt, Ryobi and Toro.

The adoption rate for electric edgers will be about 80% by 2026, up from 60% this year.

Hedge cutters Hedge cutters are following a similar growth rate as edgers this year at about 8% from 2020 sales. Electric hedge cutters already account for 75% of the market currently. That will continue to grow over the next 5 years and IC units will only account for less than 10% of the market.

Leading players for hedge cutters include STIHL for both IC and electric

OEM Off-Highway | SEPTEMBER 2021

units, Black+Decker, Sun Joe, Echo, Makita and Ryobi.

Leaf blowers and leaf vacuums Leaf blowers and vacuums are also products within the handheld category of lawn and garden equipment in the U.S. Sales of this application in the U.S. are projected to grow 8.5% over 2020.

Blowers are becoming more and more popular with homeowners as they are easy to use and very versatile.

Sales volumes are projected to be close to 1.5 million units in 2021. The leading brands are Black+Decker, Echo, STIHL and Greenworks. Currently the market is 80% electric drive and again that will only increase by the year 2026.

Trimmers The last product to discuss in the handheld segment is the trimmer. This tool is also known as a string trimmer, weed whacker and weed whip. Trimmers use a flexible line/string instead of a blade to cut. Sales of trimmers in the U.S. are expected to increase between 8 and 9% in 2021 compared to 2020.

That growth will continue for the next 5 years and will increase 19% from 2021-2026. Electric models have 62% market share. As with the other handheld products, electric trimmers sold in the U.S. will continue to grow and be over 80% of the market by 2026.

Gasoline trimmers are still favored by contractors. The leading producers of trimmers are Troy-Bilt, STIHL, Sun Joe, Black+Decker, and Husqvarna.

U.S. lawn and garden equipment sales have done well during the pandemic as many people are working from home and finding more time to work on their outside property. Lawns, gardens and foliage have been tended to more often now than in the past.

Hence more lawn and garden equipment has been sold. Rising consumer confidence and more disposable income has prompted spending, which has driven the demand for new equipment. | This article was written and contributed

YOKOHAMA OFF-HIGHWAY TIRES AMERICA

DRIVETRAIN SYSTEM: TIRES oemoffhighway.com/21590930

Yokohama Off-Highway Tires America offers a wide range of compounds based on the uses of the tire, from standard multi-use RE-R compounds to special compounds for extra heat resistance (HR-V) or cut resistance (CP-S).

Select Wheel Loader Tires to Meet Jobsite Demands Selecting the right tire can help an OEM ensure customers minimize operating costs while improving wheel loader productivity. by Curt Bennink

S

electing the best wheel loader tire can have a dramatic impact on operating costs.

“Two of the most common triggers for tire failure for wheel loaders result from mismanagement of tire maintenance, or choosing the wrong tire for the application,” says Robby Hamby, Director, Bridgestone OTR and Ag Product Programs. It’s critical that the right tire type, rating and pattern are selected.

The size and capacity of the wheel loader affects the correct choice.

“Choose a tire with the load capacity that meets or exceeds the gross vehicle weight of the loader,” adds Hamby.

“We can look at wheel loader size in three ways: the gross weight of the machine itself, the capacity of its bucket and the horsepower and torque the loader exert on the wheel,” says Bruce

24

Besancon, Vice President, Yokohama Off-Highway Tires America. “As any of those three measures increases, demands on the tires grows significantly.

“Every aspect of a tire is engineered and manufactured with those demands in mind,” he adds. “The ability of the entire tire to handle a load – particularly a dynamic load that is changing as the bucket is raised and lowered – the capacity of the bead and sidewall to withstand the force from the axle, and the capability of the tire to flex and roll without building up excess heat are all critical. Buying more tire than you need does not make economic sense, but neither does buying a tire that is under-spec’d for the application and doomed to fail.”

“Bigger machines carry heavier loads, which can translate into more heat buildup,” explains Laurent Greppi,

OEM Off-Highway | SEPTEMBER 2021

Global Product Category Manager, Camso Inc. Choose the right rubber compound to avoid premature wear.

Also consider the operator. “When selecting a tire for bigger machines, operator fatigue is an important issue.

Just changing the tires could have significant impact on vibration levels in the cabin, leading to stress, fatigue and ultimately safety issues. Talking to operators regularly about machine performance, especially after changing tires on your loaders, can be an effective way to assess performance.”

Choose tires based on application “Wheel loaders are typically purpose-built for very specific applications and demand tires that are just as specific to the material being dug and moved, the surface condition and the distance

and speed of travel,” says Besancon. “With those factors in mind – as well as the bucket size and the load to be carried – you can choose the tire with the construction, tread depth and pattern, and compound for the application.”

“There are many factors to consider: the type of machine used, its size, the application for which it is used and the type of operations it carries out,” says Pireo Torassa, Field Engineer at BKT Europe. “Another essential factor in selecting the best tire is the condition of the soil in which it works.” Work times, distances covered and type of route are also factors. Finally, consider the weight which the machine must transport, load and/or unload.

“To extend the life of a tire, it is necessary above all to choose the perfect product for your needs,” says Torassa.

“We always tell customers to put their trust in our tire consultants and suppliers.

These are increasingly specific and hi-tech products. It is the expert’s task to successfully translate each company’s requirements into selecting the perfect tire. By choosing the right product, you save on time, consumption and possible replacements and downtime.”

Radial versus bias You need to decide between radial or bias tires. “Radial tires offer better cut resistance, improved traction and cooler running that will maximize uptime, while

bias tires offer more stability, which will provide better ride comfort in larger loaders,” says Hamby.

Longer travel cycles tend to build up heat. “That is where you do the math on whether to invest in radial tires that can allow you more ton miles per hour (TMPH) because they can operate more safely and efficiently over longer distances,” says Besancon.

A radial tire tends to be more expensive than a bias tire. However, the machine’s total cost of ownership may be lower because the radial provides better traction and flotation. It also contributes to lower fuel consumption.

Radial tires are ideal in applications where traction, tread wear and distance are important factors. They are well suited for wheel loaders operated on finished surfaces for loading applications.

Choose correct tire tread After determining the best tire type for the application, the next step is to select the tread pattern or tire design. “The correct tread design, tread depth and load capacity are key in determining the correct tire that will maximize your loader’s performance,” says Hamby. “It’s important to understand whether you are looking for a tire that provides better heat resistance, cut resistance There are many types of treads and tread depths.

Understanding the application and the tradeoffs will ensure the best tire choice.

Fewer lugs and more voids lead to more traction. This is because the tread can clean out much faster to provide grip in each revolution a tire makes.

The correct pressure will allow the tire to carry the load it was designed for and the casing will deflect correctly.

Selecting the right tire for the right application is vital to ensuring optimal performance.

and traction, or wear to improve total cost of ownership.”

L-type tires are designated for wheel loaders and wheeled dozers, while there are also E-type tires for earthmovers, G-type tires for graders and C-type tires for compactors. For the loader tires, there is a standardized identification code: • L2 Traction Regular Tread Depth • L3 Rock Regular Tread Depth • L4 Rock Deep Tread Depth • L5 Rock Extra Deep Tread Depth • L4S Smooth Deep Tread Depth • L5S Smooth Extra Deep Tread Depth According to the Tire and Rim Association, there are three general classifications for tread thickness – regular, deep and extra deep. Deep and extra deep are 1.5 and two times thicker, respectively, than regular.

“Balancing the need for cut/wear resistance and heat dissipation can dictate whether the best investment is in regular tread (an L2 or L3 tire), a deep tread that is 50% deeper (L4) or extra-deep tread (L5), which is 2.5 times the depth of a regular tread,” says Besancon.

Knowing the loader’s application is critical to understanding which tire to run. “For example, if the loader is used to load out over the road trucks at a stone quarry, one might consider an L3 tread design,” says Tim Good, Open Pit Sales Manager, Maxam Tire. “But if the loader is used in multiple appli-

cations like feeding shot rock into the crusher and then loading trucks with the finished material, one should consider an L4 application. The L4 provides a deeper tread for more protection, traction and longer wear due to a deeper tread. An L5 loader tire should be considered when working in any moderate to severe underfoot conditions.” The deeper 250 level tire maximizes protection of the casing.

But with that deeper tread option, the user is limited to 5 mph (8 km/h) for no more than 250 ft. (76.2 m).

“If the loader currently has a wide base (80 aspect ratio) tire, you can go from an L3 to an L5 tire,” notes Good.

“What the loader is used for determines the tread pattern and tread depth required. Other options include a low profile (65 Series) aspect ratio tire. Generally, the loaders are ordered from the factory with the low-profile tires as the tires require a wider rim.

For example, if the loader is fitted with 29.5R25 tires, one can convert over to 875/65R29 tires with new rims. The overall diameter of the tires is equal even though the rim O.D. goes from a 25- to 29-in. rim (63.5- to 73.7-cm).

Plus, the 65 series tire fits on a 2-in.

(5.1-cm) wider rim. The advantage to the user is that the low profile 65 series tire, when mounted on a loader, has a 15% increased capacity, providing more productivity with improved ride, stability and traction.”

Match tires to underfoot conditions

26

OEM Off-Highway | SEPTEMBER 2021

Underfoot conditions will have a major influence on correct tire choice. “If the piece of equipment is being operated in a very soft underfoot condition, one would need to consider an L2, L3 or even L4 depending upon what the machine is doing,” says Good. “The difference is lug to void ratio. The fewer lugs and the more voids lead to more traction. This is because the tread can clean out much faster to provide grip in each revolution a tire makes.”

There are tradeoffs. Normally, the higher the net (lug) to void (space between the lug) ratio the more wear.

“One cannot obtain a high net-to-void ratio without getting less traction,” explains Good.

“When the machine is placed into a ‘load and carry’ operation, it’s crucial to note underfoot conditions,” says Good.

“If the machine is operating in the pit area loading shot rock from the face to the in-pit crusher or conveyor, one needs to decide between an L5 deep rock tread tire or an L4 rock tread tire.

This will depend on the loaders’ travelling distance. If greater than 250 ft. and faster than 5 mph, then an L4 should be considered.”

Each jobsite poses unique demands. “If we’re working at the face of a quarry, that loader is operating on broken rock – a brutal environment for cuts and impact damage,”

says Besancon. “On the other hand, it is probably not traveling very far to dump its bucket, so heat buildup may not be the primary factor that needs consideration. We can specify a very deep, cut-resistant tread that can withstand the rock without as much concern about the thick tread trapping heat in the tire. In another case, aggregate or sand may be lifted and hauled a much greater distance across a better surface. In that situation, the tire is not as likely to be subjected to the impact, but heat buildup from friction and deflection is the bigger concern. A tire with heat-dissipating nylon breakers and compound would be a better choice.”

“Once we’ve got the basics down, we can look at value and cost per hour,” says Besancon. “In some applications, radial tires quickly become a better investment because they last longer, wear more evenly and reduce fuel consumption because of their flatter, more even footprint. On the opposite end of the spectrum, loaders in severe duty situations like scrap yards or waste transfer stations can benefit dramatically from switching to solid tires, which wear longer and are impervious to flats and punctures or sidewall cuts.

Even foam-filled pneumatics can be sidelined when the sidewalls are slit, so it’s worth the extra cost of a solid tire in those tough cases.”

“Compound chemistry is extremely important and it has been an important focus for Yokohama for decades,” says Besancon. “We offer a wide range of compounds based on the uses of the tire, from standard multi-use RE-R compounds to special compounds for extra heat resistance (HR-V) or cut resistance (CP-S). There is both

art and science in selecting the best compound for a particular application based on the tradeoffs among heat, abrasion and cut resistance. That is a conversation you’ll want to have with a tire dealer who understands your business and your equipment. That dealer can save you a tremendous amount of money and trouble.” |

by Curt Bennink display. It could be your phone.”

“Everybody has been focusing on the big equipment — dozers, graders and excavators. But we never really looked at the smaller excavators, the compact tools like the skid steers,” notes Kris Maas, Machine Control Director of Product Management for Leica Geosystems, part of Hexagon. “We are definitely looking to those solutions. The cost was too high compared to the cost of the machine. It is getting less expensive and more accessible to a different fleet of machines.”

Accuracy and processing power improve TOPCON

T

he pace of innovation continues at an exponential rate.

“In the past couple of years, we have seen tremendous growth in the adoption of machine grade control solutions,” says Sean Mairet, Product Marketing Manager, John Deere Construction & Forestry.

“This adoption has led to improvements in grade control solutions such as removing external grade control components like mast towers and coil cables. Additionally, automation features are being integrated to help further enhance grade control solutions.”

As the cost of the technology has come down, it has rapidly spread to new machine types. “You are seeing

nontraditional grade control machines adopting grade control technology,” says Mairet. “Take for instance our new 333G SmartGrade compact track loader and SmartGrade excavators. These types of machines are newer to grade control but now enjoy the tremendous value grade control technology brings to a jobsite.”

Trimble offers Earthworks GO!, a product tailored specifically to expand grade control technology to the small machine space. “It’s portable and very cost effective,” says Cameron Clark, Earthmoving Industry Director for the Civil Construction Division, Trimble. “It magnetically mounts to the grading attachment. You can use your own

OEM Off-Highway | SEPTEMBER 2021

Murray Lodge, Senior Vice President and General Manager of Construction, Topcon Positioning Group, believes the most significant improvements have been the processing power of the components and the rapid advancements in Inertial Measurement Unit (IMU) technology. And while the performance has increased, the price has seen a significant decline.

“It’s really dropped because of commoditization. You are also now able to build IMUs that are more accurate,” he says.

These advancements allow machines to operate at faster speeds. “As you start to add load-sensing capability so that

you know you are getting too much resistance on the blade — you have too much material — then the blade will automatically come up a little bit,” says Lodge. “You don’t have to slow down; you can maintain a constant speed.”

Such advancements also make it possible to adapt the technology to more machine forms, such as skid steers or track loaders that rapidly change directions. “On older machine control technology, where you used gravity flow sensors, slow processors and received your signal from a GPS, the latency was so great that you couldn’t keep up,” recalls Lodge.

“You either had to slow way down to get the accuracy you needed or you couldn’t use it.”

Scott Hagemann, Senior Market Professional, Caterpillar Inc., agrees that advancements in the sensors and IMUs are the most important achievements. “They are very fast and measure many different angles with the same sensor. They are also very compact in size so they can be mounted out of harm’s way.”

“When you couple [sensor and IMU advancements] with the extra processing power we have with the ECM (engine control module), we’ve seen a real big performance improvement,” says Clark. You have more data and the ability to do more with that data.

GPS & AUTOMATION: MACHINE CONTROL SYSTEMS

Leica’s dozer grade control solutions interface with Leica ConX with easy data transfer between office and machines, remote communication, fleet management and earthmoving productivity analysis via the cloud-based ConX platform.

IMU technology has also allowed the development of mastless systems.

Traditionally, contractors remove the grade control components off the masts at night to prevent theft.

Mastless systems mean you don’t have to worry about daily removal and the risk of falling off a ladder every day, says Clark.

System displays have been another area of improvement. “The size is larger, but the touchscreen gives it the feel of your smartphone,” says Hagemann.

“They are actually tablets that run apps. The app we use for grade control is called Cat GRADE. The operator can press and hold, swipe, zoom and rotate just like your phone. This feel changes the attitude of the operator; they feel more at ease with the technology.”

“There’s been a lot of focus and effort within the industry to make the systems more intuitive,” says Clark. Trimble employs a team focused on user experience to ensure products are more intuitive, which decreases the learning curve and training requirements.

From machine solutions to ecosystems There is also a movement from standalone solutions to ecosystem solutions, where machines are connected.

“We’ve seen big improvements with workflows, of getting data to and from the office, being able to manage and understand what’s happening on the site remotely,” says Clark. The importance of this has been emphasized during the pandemic. Connected machines also allow plan updates to be remotely sent to all machines in the field.

But connectivity requires input from a fleet of machines. “If you only have one machine on the jobsite that is connected back to the office, it doesn’t really help you out a whole lot,” says Michael Salyers, Senior Product Manager, Komatsu. The more machines become connected and supply data, the more viable it will be to make decisions in real time.

The information provided by grade control systems will become even more useful as it is integrated with onboard telematics systems. “SmartGrade solutions are already integrated

OEM Off-Highway | SEPTEMBER 2021

LEICA GEOSYSTEMS

into JDLink from the factory,” says Mairet. “Recently announced, SmartGrade remote support is being added to SmartGrade machines this year.

This support suite includes remote display access (RDA) and wireless data transfer (WDT), enabling the dealer and customer to remotely log into the display to help with troubleshooting or wirelessly transfer files to the machine.”

This helps prevent trips to the machine in the field.

Machine data can be sent directly to the cloud. “No matter where you are, you can get this information by phone, tablet or computer,” says Hagemann.

This will drive new processes and efficiencies. “We can tie dirt moved to fuel burned, hours worked and trucks loaded. The data allows our customers to make decisions sooner and faster.”

Real-time information is a game changer. “You can now make better decisions and adjust project schedules, project plans, material ordering, deliveries,” says Salyers. “You can start adjusting those schedules much more effectively because you’re able to see what is happening on the jobsite in a more real-time scenario.”

The goal is to use real-time information to optimize the workflow.

“Monitoring the whole workflow is really where the big-dollar impacts can happen,” says Lodge. “If you want to get real-time accurate information of what’s happening on a jobsite, you have to be able to take different types of data collection, bring them together and then have a cloud-based system that can process all that instantly. That information needs to immediately go out to every machine, every grade checker, every foreman in a truck.”

This requires machines talking to each other, plus other forms of data collection such as drones. Topcon uses Sitelink connectivity to tie this data together.

Accessing data has been one of the challenges faced by many contractors who run mixed fleets. “When somebody buys a machine, they need to stick to a brand to get the whole ecosystem,” says

Maas. “That’s one of the constraints that you have today. If a contractor wants to get full information on productivity, they need to have one brand of machine because they live in their ecosystem. That’s still a problem in the construction industry, and they’re working on an ISO norm of data formats, which may become available by end of this year or beginning of next year.”

Looking toward the future Increasing machine connectivity will allow further advancements. “We look at it not so much as individual point solutions, but what can we do [at] an ecosystem level,” says Clark.

“More intelligence is being added to the systems to really help the skilled operators to be more efficient and productive, and assistance features aid in optimizing workflows.”

The systems will move away from being simply grade control toward

systems that instruct the operator how to complete the task. This may include heads-up displays or augmented reality.

For these advancements to occur, jobsite machines need to be connected.

“That’s where it has to go to automate the site,” says Lodge. “If I have 10 pieces of equipment on a site and only two of them have control systems, I can only do so much.” When the whole fleet is connected, the machines can work together at a higher productivity level.

“As we look out over the next 5 years,

integration, adoption and automation are the three areas that seem to be gaining attention,” says Mairet. “Integration at the factory allows for better installation consistency, and customers are seeing the value that brings to grade control

machine moving left or right, forward or reverse, and moving parts up or down. The big step in between will be remote control of our machines, then automation.”

Safety will be an important topic on the road to autonomy. “To get more to autonomy or automation, you need to have safety involved,” says Maas.

“If you’re relying less on the operator, you need to have that aspect covered.

If something goes wrong, the machine stops working.

“We already have that standard in our semi-automatic excavator today,” he notes. “The problem with a construction site is it’s so dynamic.

It changes continuously.

technology solutions. As technology adoption and integration increase, the opportunity for automation to further enhance productivity is even larger.

Grade control technology is certainly a very important building block for additional automation in the future.”

Clark says that the path toward autonomy is a journey. “It makes sense to add value along the way — to provide assistance with semi-automated

whole fleet and the whole operation.

The integrated systems and aftermarket systems can all communicate with the Topcon ecosystem.

“In the last few years, the systems actually started to become part of the machine instead of just an add-on,” says Komatsu’s Salyers. “Now, we’ve really started to see the increase in the usability and the functionality of the system as it relates to the overall jobsite. The machines understand what is happening within their own environment.” They can sense when they have too much or too little load.

Prior to the development of integrated technologies, grade control was primarily a blade-mounted system. “All it knew was exactly what the target was and how far it needed to go to get to target,” says Salyers. This limited the application to primarily finish grading.

“Contractors and operators would only use that blade control system anywhere between 10-15% of the time.”

For most earthmoving projects, mass haul of material is the largest amount of work that occurs. “That’s the highest cost for the contractor or the developer,” says Lodge. “The technology is now being utilized for general movement of any material on a jobsite.

If I automate the workflow in the beginning when I do the design, I’m going to do it as efficiently as possible.”

Being able to use a grade control system from the start of the project reduces mistakes. “It has a big benefit because you don’t want to dig too deep or over cut at the beginning.

We all know that 80% of the costs for earthmoving [are] at the beginning when they start stripping and preparing the field,” says Maas.

The early grade control systems were primarily used in manual mode until you were within a half foot of target grade. “Now, we’re able to sense what the existing ground is underneath the tracks of the machine and load the blade accordingly, thus making the machine more efficient and productive,” says Salyers. “The machine is recording in real time what it is do-

ing, comparing it to where it needs to be and then moving the material in the best way that a machine of its size can move it, whether it is a big machine or a small machine. The operator can now turn on the automation in one of our integrated machines and never turn it off all day.

“Bringing the grade control system into the machine and using the speed sensors, advanced IMUs and pressure sensors is allowing the machine to do a lot more for the operator,” he points out. “Now, the operator doesn’t have to worry about basic material movement; he is thinking about where the material placement needs to go. It is giving experienced operators the ability to do more jobsite management than it is actual machine operation.”

Machine grade control pricing has dropped substantially over the years, which makes it easier to justify an upgrade to integrated grade control

technologies. “Contractors will start to see as they replace machines, it’s much more cost effective to go with an integrated machine than it is to continually try to utilize an older system that doesn’t have some of the functionality, that doesn’t have some of the performance capabilities that the newer systems have,” says Salyers.

“Being able to combine onboard machine data and sensors with grade control technology creates an opportunity for features that wouldn’t be available in a standalone add-on kit,” says Mairet. “An example of this is the newly released machine damage avoidance feature on [John Deere] SmartGrade motor graders. This feature leverages the same sensors SmartGrade integrated grade control uses to sense if the machine is at risk of damaging itself, and actively prevents it.”

The information available from the integrated machines will just continue

to increase over time. For example, sensors are being added to track what is going on around the machine for safety. “When you look at some of the sensors that you might have on a machine for safety, how else could you use those?” Clark poses, then notes that they might also be used to scan and create surface models around the machine, providing additional value.

As machines gain data gathering capability, you may be able to rely less on drone mapping. “There will be cameras on the machine where you can start tracking data. Excavators can have a camera on the front and they can collect [data] points while they dig,” notes Maas.

Reality capture technology is also emerging. “You can capture reality around the machine and you can map the terrain while driving,” says Maas.

While this capability is not yet available, the technology exists. |

The First Self-Propelled Scraper Although not as successful as other LeTourneau designs, the first self-propelled scraper featured technologies that would years later become industry standards.

LeTourneau’s Self-Propelled Scraper was many years ahead of its time in both its concept and powertrain. It’s doing work a tractor-drawn scraper could not, discharging fill to the end of a levee with its front axle chocked.

Mountain Mover, a scraper of far larger capacity than anything else of the time (read more, 21508912 and 21551345).

These scrapers had one drawback— they had to be pulled by a separate tractor. In his incessant pursuit of a better way to do the job, LeTourneau took scraper design to the next logical level in 1923: self-propulsion.

The “Self-Propelled Scraper,” as he called it, rode on four large, smooth, spoked steel wheels. A gasoline engine, transversely mounted ahead of the front axle, turned a dynamo that

and the operating principles of the two-section bowl, the Self-Propelled Scraper didn’t have the power and traction to load that much material in two sections, so more and smaller sections were needed.

Unfortunately, this remarkable machine had one drawback – its stately 1 mph (1.6 kph) speed. It could move the material, but much slower than tractor-drawn scrapers. After using it on various projects in central California, LeTourneau ended up converting it to a pull scraper and then sold it in 1925.

Even though it was ultimately a failure, the Self-Propelled Scraper was years ahead of its time. It predated modern motor scrapers, also developed by LeTourneau, by 15 years.

Its powertrain, with a generator set powering an array of motors at working points of the machine, foretold by 22 years the diesel-electric systems that became LeTourneau’s hallmark. After World War II, LeTourneau committed to this means of powering machinery, and his mammoth LT360, at 360 tons or 216 cubic yards capacity, the largest scraper ever built, had exactly the same power concept as the Self-Propelled Scraper – albeit with 5,080 hp (3,788.2 kW) worth of diesel generators. |
