Based in Milford, New Hampshire, Leighton A. White started as a part-time custom farming business that maintained acreages in 1978. It’s grown to a large, well-respected site-excavation contractor that provides commercial, industrial and municipal site work, and runs five gravel and sand pits.

Today, Leighton A. White has 50 employees and an expansive equipment fleet that includes 80 pieces of equipment and trucks. The company purchases four to five pieces of equipment each year as it upgrades its fleet and continues to grow.

Leighton A. White provides a full range of small to large equipment and services to contractors and customers in New Hampshire and Northern Massachusetts. They also supply a wide selection of stone, round stone, erosion stone and crushed stone base in a range of sizes. Sand, screened sand, presby sand, septic sand, stone dust, crushed aggregate, RAP and more are also offered.

Building on a reputation

Dale White, President of Leighton A. White Inc. This site work contractor built a loyal customer base by emphasizing quality over cost in an industry traditionally built on the lowest-cost bid.

But you cannot argue with results. Repeat customers and their acquaintances account for 80% of the company’s current business, all because of their solid reputation. The company’s philosophy is best summed up by one of President Dale White’s favorite quotes, “A competition for cheapness and a competition for excellence will always be strangers.”

In our industry, we’re known not to be the lowest price,” said White. “Competitors may be able to undercut the price, but they cannot compete against the quality. You want to set the bar high.”

Forming partnerships

This thought process carries through every aspect of the business and Leighton A. White seeks out equipment partners that adhere to the same business philosophies. This site work contractor places a high value on reputation and has turned to Chappell Tractor Sales for sales, service and support.

“Since 1978, we have bought a tremendous amount of equipment from Chappell Tractor Sales,” noted White. “They have a tremendous reputation in this industry. It’s not just the equipment, it is the service that is key. That is as important to me as the piece of equipment. I don’t think there is any other dealer in New Hampshire that has as many service vehicles on the road as Chappell Tractor Sales does.”

Due to the short construction season, uptime is a top priority for the company and it needs a dealer who can rapidly respond.

“In New Hampshire, we have eight months a year to make a living because four months is cold and snow,” White shared. “It is such a short season. That’s why it is important to buy the right piece of equipment.”

A recent partnership between Chappell Tractor Sales and Hitachi Construction Machinery Americas presented Leighton A. White the opportunity to upgrade their equipment fleet while maintaining top-quality dealer service.

“I always felt Hitachi Construction Machinery had a premium product, especially in the mining industry,” said White. “If your equipment can stand up in the mining industry, you cannot get a higher bar than that. There is nothing more abrasive than stone.”

People first

White emphasizes that employees are the most important asset to the company. This view drives the equipment selection process with ease of use and comfort particularly important.

“If you buy good equipment, it takes care of the employees,” explained White. “Quality is going to cost more money. I am willing to pay a little more for that quality.”

The site work contractor recently purchased two Hitachi Construction Machinery Americas models — a ZW370-6 wheel loader and a ZX350LC-6 HP excavator. Both machines have impressed with the available power ratio — this includes the power to the wheels for the loader and the power to the hydraulics for the excavator.

“I just can’t find anything wrong with those two machines,” said White. “I have a wheel loader operator who runs another brand. That operator has made it very clear that the next one I own must be Hitachi Construction Machinery Americas and it has to have stick steering. That’s what the operators like.”

Even the most discerning operators find few faults in Hitachi Construction Machinery Americas equipment.

“My son Bronson is very picky with equipment. On a new piece of equipment, he picks it apart. The ZX350LC-6 was the first piece of equipment that he has ever run that checked off all the boxes the first time.”

– Dave White, Leighton A. White president

“The ZX350LC-6 was balanced right. It had tremendous hydraulic power. To us, imbalance is a huge thing, especially when you are lifting heavy loads,” added White.

Technology that makes sense

While technology is rapidly advancing in the construction equipment sector, operators at Leighton A. White prefer machines that avoid unnecessary complexity. The technology should increase machine efficiency, not make it more complicated to operate.

“Hitachi Construction Machinery Americas engineers have kept the product simple,” explained White. “Some competitors make their product so complex. Hitachi Construction Machinery Americas has found a balance between technology and the simplicity of buttons and knobs. Keep it simple for the employees. A loader is a loader and an excavator is an excavator.”

The Hitachi Construction Machinery Americas customer-first approach to design also helps drive uptime.

“Some manufacturers create so much additional cost to the end user because everything is so technical. It costs money because a sensor fails, so you have downtime,” said White.

Standing behind the product

Leighton A. White takes a very proactive approach to maintenance.

“We do all our own preventive maintenance,” White explained. “When we sell a piece of equipment, we provide the maintenance log. It helps sell the equipment because buyers see how well we maintain it.”

But this proactive maintenance does not diminish the need for dealer support.

“It’s one thing to buy a new piece of equipment, but sooner or later you need parts and service. We have three mechanics in our organization. But you need the technical backing. You need the dealer’s technical skill set that sometimes we just don’t have.”

Parts availability is also a priority for this site work contractor.

“It’s one thing to have a new product and a good product, but like everything else, it wears. There’s nothing worse than not having parts. This past year it has been very frustrating just overall finding parts. Chappell Tractor Sales does a tremendous job in stocking parts. They understand the cost of being down.”

Looking to the future

Leighton A. White looks to further expand its partnership with Hitachi Construction Machinery Americas and Chappell Tractor Sales. In addition to being a site work contractor and running five sand and gravel pits, the company is considering a return to the quarry market. This will require equipment, like the ZW370-6 wheel loader, that can endure the brutal rock conditions.

“I bought a Hitachi Construction Machinery Americas excavator and a wheel loader because they are quality pieces of equipment,” said White. “They had proven themselves in the mining industry and the aggregate industry for years. They were also priced in an area that I felt was very fair. For the longevity of owning the piece of equipment, I felt it would be a good purchase for our company and our people.”

Oil and natural gas companies consume massive quantities of frac sand. Up to 10,000 tons (9,071.8 MT) of frac sand can be used for each well. To keep up, companies that supply the sand must efficiently operate around the clock with minimal downtime. MPR Transloading Supply Chain Solutions (MPR), located in Bellaire, Ohio, is well positioned to tackle this task.

The facility is a Gateway Distribution Point, minutes away from major north-south, east-west transportation routes and within 24 hours of both the United States and Canada including some of the largest material-consuming regions in the country. The logistics company uses the latest transloading equipment and technology to efficiently move materials. It uses the largest material handlers in the region, allowing more material to be quickly moved.

MPR Transloading Supply Chain Solutions is a family-owned and operated riverfront transloading facility that began in 2009 with three employees. The company quickly expanded and currently employs 40.

Frac sand presents opportunity

MPR President Natalie Brown In late 2015, MPR Transloading Supply Chain Solutions opened a frac sand terminal to support the fracking process in the oil and natural gas industry. Frac sand is injected into rock formations along with water. The sand props open fractures created during the hydraulic fracturing process to allow oil and natural gas extraction. Due to the company’s location in relation to the well sites, MPR Transloading Supply Chain Solutions has become a premier outlet for frac sand, using its transloading equipment to move large quantities with minimal disruption.

“We handle the logistics. “We load trucks 24 hours a day, 365 days a year,” said MPR President Natalie Brown.

Wheel loaders serve a critical role in handling the sand. Twelve to 16 operators keep two Hitachi Construction Machinery Americas ZW250-6 wheel loaders in constant motion

“We currently handle between 1 and 1.25 million tons (.91 to 1.14 MT) of sand a year,” she said. “We unload approximately 570 barges of sand a year. The wheel loaders are being utilized to move that sand after it is moved into the storage building.”

Overcoming transloading equipment challenges

Handling this fine sand presents several unique challenges for workers and transloading equipment. It is not like any other sand. It is made from tiny pieces of quartz-silicon dioxide that is only found in a few places, mainly in the Midwest near the Great Lakes. This abrasive, crush-resistant quartz sand can be as small as .004 inch (0.1 mm) and often ranges in size between .016 inches and .031 inches (0.4 mm and 0.8 mm). With these fine particles, any disturbance can create airborne dust.

“Due to the sand being silica sand, it’s a very dusty environment,” Natalie explained. “We have to protect our equipment and we have to protect our employees. We do rigorous health testing for our employees and they utilize special breathing apparatuses to work inside the buildings. We even require protection inside the loaders.”

This is a brutal working environment for heavy machinery. The airborne, abrasive fine particles can easily damage and shorten the life expectancy of an internal combustion engine if allowed to enter the combustion chamber. Stock air filtration systems are not designed to capture a large quantity of these extremely small particles. MPR turned to local Hitachi Construction Machinery Americas dealer RECO Equipment for a solution. RECO Equipment, Inc. solved the challenge by fitting MPR’s wheel loaders with specialized air filtration that allow them to reliably operate in this unique environment.

Performance of the Hitachi Construction Machinery Americas wheel loaders, backed by the support of RECO Equipment, has proven valuable optimizing transloading equipment fleet efficiency.

“We’ve used several different brands, but we like how the Hitachi Construction Machinery Americas loaders perform, coupled with the parts availability,” said MPR Vice President of Operations Justin Brown.

Matching job site requirements

Vice President of Operations Justin Brown Before MPR considers any wheel loader for its operation, the machine must meet several job site criteria. Each wheel loader must be able to maneuver in tight quarters with a small turning radius and meet the height clearance restrictions between the two buildings used to store the frac sand.

“The ZW250-6 meets all the requirements that we need to operate in our facilities. This includes the clearance when dumping into hoppers,” noted Justin.

The company uses a rollout bucket to allow the wheel loader to dump over its hinge pin height. An oversized 5.5-cubic yard (4.21 m3) bucket optimizes the ZW250-6 wheel loaders for the application. The 253 HP (186 kW) loaders have the power required to perform in the dense frac sand, which weighs about 3,000 lb/yd3 (1,779.8 kg/m3).

Natalie added that visibility is considered when comparing wheel loaders. Backup cameras on the ZW250-6 wheel loaders are important in this application since the machines maneuver in tight quarters inside the buildings.

No time for rest

The ZW250-6 wheel loaders remain in constant motion, running an average of 5,000 hours throughout the duration of the two-year lease. MPR depends on these loaders to keep frac sand flowing through its facility and to keep customers happy. Equipment is turned frequently due to its high utilization.

Functionality is important to the operators, which is also a job site requirement. This includes ease of maintenance.

“One operator mentioned that when you open the hood, all the vitals that need to be checked are right there,” said Justin. “The operator doesn’t have to walk around the machine to perform checks. It makes it easier for them.”

Ensuring the operation runs smoothly is another area where RECO Equipment plays a critical role in MPR’s success. They monitor and maintain the wheel loaders with ConSite Global e-Service to track upcoming maintenance needs and minimize downtime.

MPR realizes the benefits offered through ConSite Global e-Service and is working with RECO Equipment to get important notifications sent directly to its management staff.

“The output of the faults that are emailed out, that’s an added bonus so that we know if there is an issue,” Natalie said. “It is very nice to be alerted if there is an issue that arises so we can react immediately and not wait until something fails. We can fix it before it becomes a catastrophic failure.”

At the end of the day, MPR promises to move materials wherever they need to go without any headaches along the way. In its frac sand business, the reliability and performance of ZW250-6 wheel loaders allow the company to achieve that goal.

Hitachi Construction Machinery Americas introduces the ZAXIS-7 compact excavators to efficiently complete tasks on today’s urban job sites. An ultra-short-tail swing radius on the ZX75US-7 allows access to confined spaces while an ultra-short-tail swing radius with swing boom model ZX85USB-7 productively digs next to walls and guard rails.

Power is provided by proven, turbocharged Yanmar diesel engines. Power/economy work modes tailor the machine’s performance to the task. The power mode provides higher engine speeds when extra horsepower is needed, while the economy mode reduces engine speed when performing normal work. This results in lower noise and decreased fuel consumption.

A standard auto idle system automatically reduces the engine to idling speed when all control levers are left in neutral for longer than 4 seconds. When the levers are moved again, the engine speed immediately resumes to the pre-selected engine speed. This reduces noise and exhaust emissions, while simultaneously saving energy and running cost.

Enhanced versatility

Compact excavators are commonly used as tool carriers with a wide range of attachments that increase job-site versatility. An optional attachment replacement support system simplifies swapping work tools. Attachment flow settings can be adjusted from the monitor and the operator can name and store up to 12 settings. An auxiliary function lever (AFL) is available with an analog switch, trigger switch and horn for running attachments such as a breaker or an attachment with swing.

An additional counterweight can be selected for better stability in certain applications.

A standard blade float feature allows the blade’s own weight to smoothly grade with simple control-lever operation. There is also an optional angle blade with blade float.

Work in comfort

The ZAXIS-7 series has been engineered to maximize operator productivity. Cab space has been significantly enlarged versus the previous generation. There is more head clearance when opening the front window. A low cabin floor height allows improved access.

Designing cabs with panoramic visibility helps create a safe and comfortable working environment. Hitachi Construction Machinery Americas takes this a step further with its Aerial Angle peripheral vision camera system. It provides a wide 270-degree bird’s-eye view of the machine’s immediate environment. The operator can quickly and easily select from five views on the monitor. A camera allows the operator to see the area right below the counterweight.

An air suspension seat provides all-day comfort while the soft pad-style armrests can be adjusted for height and angle without tools. Switch positions and the keypad with jog control have been relocated to an easy-to-reach location for reduced fatigue. An 8-inch (20.32-cm) antiglare LCD monitor provides visibility even in bright surroundings. The monitor also controls the Bluetooth radio. The operator can listen to music and make hands-free calls from the cab.

A 5-volt USB power supply allows the operator to charge their smartphone or portable audio device. A hot and cold storage box routes air from the air conditioner to store up to a 16-ounce (500-ml) bottle.

Standard long-lasting LED work lights offer a longer lifetime than halogen lights and provide visibility in challenging conditions. The work lights continue to light up for 30 seconds after the power is turned off for increased safety when exiting the cab at night.

Engineered for durability

Hitachi Construction Machinery Americas excavators are renowned for durability and the ZAXIS-7 series features enhancements to critical components such as the arm and boom. Tighter pinhole tolerances in the boom and arm reduce any side wobble.

A V-shaped cylinder guard helps protect the boom cylinder from objects that may fall from the bucket. To prevent damage to the upper structure, a D-section frame skirt and increased plate thickness improve upward impact resistance. The side plate thickness of the blade has been increased to withstand external shocks.

Easy to maintain

Ease of maintenance is a priority. A wide opening rear engine cover allows maintenance access. The filters and fuel/water separator are grouped in the pump room for easy ground level inspection and replacement. Features such as remote swing-circle lubrication simplify daily maintenance.

Routine checks, such as engine oil level, are quickly accomplished from ground level and all service points are easily reached through the handy access panels. The operator is alerted of hydraulic oil and fuel filter replacement timing through the multifunction monitor. An inner element of the engine air filter protects the engine from dust ingress while cleaning the outer element.

Using telematic tools to monitor machine health helps boost uptime. ConSite, which remotely monitors operational status and alerts owners and operators to upcoming maintenance needs, is making a leap forward.

A new optional feature, ConSite OIL, monitors engine and hydraulic oil conditions to proactively catch issues before any fault codes are triggered in the machine. This helps drive uptime by catching oil degradation before damage to critical systems can occur.

ConSite Air allows the excavator to be diagnosed remotely. It also allows remote updates of the software. The servicing dealer can remotely diagnose issues that may arise, leading to increased uptime. The ConSite response team is on standby to rapidly resolve issues as they emerge.

Hitachi Construction Machinery Americas ZAXIS-5N compact excavators range from 1.7 to 6 metric tons (1.10 to 6.61 U.S. tons) and have been upgraded to enhance attachment versatility and performance. Operators can more efficiently complete work in congested urban areas thanks to the maneuverability of these compact machines that feature either a short-tail swing radius (U) or ultra-short-tail swing radius with swing boom (USB). These machines can set up and work almost anywhere.

“We continue to build on the capability of our compact excavators to efficiently run a wide selection of attachments. Recent ZAXIS-5N compact excavator updates further enhance attachment performance,” said Kei Matsumoto, product manager of compact excavators at Hitachi Construction Machinery Americas.

ZAXIS-5N compact excavators are commonly used as tool carriers with a wide range of attachments, increasing job site versatility. Several features enhance attachment compatibility. For instance, standard auxiliary hydraulic lines have been pre-plumbed to the end of the boom on the ZX17U-5N and to the middle of the arm on the ZX26U-5N to ZX60USB-5N. A standard wedgelock quick coupler makes attachment hookup a snap. A factory-installed bracket for a thumb cylinder simplifies thumb installation.

The Hitachi Construction Machinery Americas ZX30U-5N and ZX35U-5N compact excavators have been updated to include an auxiliary flow rate change switch for additional attachment flexibility. The operator can match the flow rate of the auxiliary hydraulic circuit to the requirements of the attachment being used with either a low or high setting.

An available auxiliary function lever (AFL) includes an analog switch, trigger switch and horn for running attachments such as a breaker or an attachment with swing.

A standard dozer blade enables the ZAXIS-5N series to grade while providing extra stability. An optional angle blade is available on the ZX35U-5N, ZX50U-5N and ZX60USB-5N excavators.

Efficient operation

All ZAXIS-5N series compact excavators are powered by proven, fuel-efficient Yanmar diesel engines.

The ZX30U-5N to ZX60USB-5N compact excavators incorporate power/economy work modes. The power mode provides higher engine speeds for most general digging work, while the economy mode reduces engine speed for lighter digging jobs. This results in lower noise and decreased fuel consumption.

An auto-idling system available on the ZX30U-5N to ZX60USB-5N further reduces fuel consumption, emissions and noise.

Big comfort in a small package

Operator comfort is key to productivity. Ergonomic hydraulic pilot valve control levers reduce fatigue and provide smooth control. Full hydraulic pilot controls for the bucket/thumb and other attachments, boom, swing, travel and blade maximize controllability and ensure smooth operation. Swing boom and foldable travel pedals are positioned for easy operation while allowing plenty of foot room.

Spacious operator stations have wide entryways, making entering and exiting the cab safe and easy. An updated 3-inch seatbelt provides additional comfort for operators.

Durability built in

Compact excavators in the Hitachi Construction Machinery Americas lineup are built to the same durability standards as the larger machines that operate in the toughest conditions. Cylinders and hoses are well protected. The ZAXIS-5N compact excavators feature a V-shaped boom cylinder guard and protected hoses on the boom and arm.

The ZX30U-5N to ZX60USB-5N feature a D-frame that protects the underside of the revolving platform from damage in demanding applications.

Easy to maintain

Compact machines have a reputation for being more challenging to maintain, but not the Hitachi compact excavators ZAXIS-5N. While all the components are packaged in a small space, Hitachi Construction Machinery Americas engineers ensured easy access. A hinged door provides wide-open access to the side-by-side oil cooler and radiator core for easier cleanout. The engine cover slides vertically with less rear projection for ease of maintenance in confined spaces. An operator will no longer bump their head on the cover during inspections.

Routine checks, such as engine oil level, are quickly accomplished from ground level. Daily maintenance points are grouped behind easy-access covers. Spin-on filters provide quick, easy access for filter maintenance. Ground-level at-a-glance gauges ease daily inspection and servicing.

The top of the track frame on Hitachi Construction Machinery Americas models from ZX30U-5N to ZX60USB-5N has been sloped for easy mud removal. Grease-impregnated HN bushings and pins provide 500-hour lubricating intervals.

To reduce the cost of repair, the traditional curved glass used in the cab has been exchanged with more easily obtainable flat glass.

The updated ZX30U-5N to ZX60USB-5N compact excavators are now prewired for compatibility with the fleet’s existing telematics system. They can be connected to Global e-Service, which remotely monitors operational status and alerts owners to upcoming maintenance and repair needs from fault codes. The hour meter and machine position information captured allows for better fleet management.

All Hitachi compact excavators ZAXIS-5N now come with a battery disconnect switch that prevents battery discharge during long-term storage. This eliminates the need to disconnect battery cables and avoids unanticipated downtime.

The ZX245USLC-7 uses next-generation TRIAS III technology that provides quick response to all control inputs while minimizing losses in the system. The ZX345USLC-7 relies on proven TRIAS II technology that ensures efficient use of available power.

The ZX245USLC-7 features a new arm roll-in metering control valve that allows hydraulic pump power to be reduced when the arm is operated with a low load. When digging, the roll-in metering control valve reduces hydraulic pressure loss to the tank. This decreases the pump power needed for digging operations, improving fuel efficiency.

The ZX245USLC-7 and ZX345USLC-7 allow attachment/arm priority to be adjusted on the monitor to match the attachment or the operator’s preference. When the attachment and arm are operated at the same time, the operator can adjust whether the speed of the attachment or the arm should be prioritized. The operator can also adjust boom raise priority using the monitor. This can tailor the machine for everything from truck loading to heavy digging.

Proven Isuzu engines power all three models, producing 100 net horsepower (74.9 kW) for the ZX135US-7, 164 net horsepower (122 kW) for the ZX245USLC-7 and 249 net horsepower (186 kW) for the ZX345USLC-7. Economy, power and high-performance modes best match available power to the working conditions while an auto idle system with auto shut-down control prevents wasted fuel.

Enhanced operator environment reduces fatigue

A first-class cab ensures operator comfort and reduces fatigue. It starts with a larger cab with increased head clearance. A one-touch adjustable air suspension seat is synchronized to move with the console. Noise has been minimized by increasing the thickness of the rear glass. Improved airtightness of the cab keeps the dust out, even when the air conditioner is started.

Cab mounts reduce vibration when traveling. An 8-inch (20.32-cm) anti-glare LCD monitor provides visibility, even in bright surroundings. It also controls the Bluetooth radio. The operator can listen to music and make a hands-free call from the cab. Long-lasting LED lights provide visibility in challenging conditions.

A dealer-installed option on the ZX130-7 and ZX160LC-7, ConSite OIL, monitors engine and hydraulic oil conditions to proactively catch issues before any fault codes are triggered in the machine. This helps drive uptime by catching oil degradation before damage to critical systems can occur. This allows operators to focus on the work that needs to be done.

The 4-cubic-yard Hitachi ZW220-7 wheel loader is an efficient loading tool available in both standard and high-lift arm configurations. It features a 41,035-pound (18,613-kg) operating weight and is powered by a proven 210 horsepower (157 kW) Cummins engine. Power is transferred to the ground through a five-speed transmission and limited slip differentials for effective job site traction.

“The next-generation ZW-7 wheel loaders feature upgraded technology for advanced productivity, enhanced operator comfort, improved serviceability and new safety features with a rear collision detection system,” says Matt Koester, product manager, wheel loaders Hitachi Construction Machinery Americas Inc.

Tools boost productivity

Approach speed control, an auto power up function and a new payload weighing system raise productivity of the ZW220-7 to new heights. The approach speed control sets the desired speed the wheel loader will achieve as it approaches a loading point. The operator holds down the accelerator while lifting the load and the machine maintains the slower speed as it approaches the loading point. The operator taps the brake to bring the machine to a complete stop when it reaches the dump area. With approach speed control, the travel speed can be adjusted with fewer pedal operations during loading. This reduces operator fatigue and fuel consumption.

The auto power up function increases hill climbing performance. It identifies slopes and adds power to prevent the engine speed from dropping when travelling uphill.

New for the ZW220-7, a payload weighing system uploads information reporting productivity to the ConSite telematic system. Operators can check the weight of the load in the bucket from the inside cab monitor and log the material loaded. It offers four modes — tip-off to truck, tip-off to pile, auto-add and manual-add. These modes allow the payload weighing system to manage loads according to their application. In addition, the unit is equipped with a warning function that reacts when the bucket is overloaded, improving safety during operation.

Operator comfort is a priority

Hitachi Construction Machinery Americas Inc. improved the overall comfort of the ZW220-7 a with larger and quieter cab. A seat-mounted armrest with low effort electric hydraulic controls, ergonomically located switches, adjustable seat and mirrors further enhance operator comfort. An 8-inch (20.3 cm) anti-glare LCD monitor with Bluetooth radio allows hands-free phone capability.

Designing cabs with panoramic visibility helps create a safe and comfortable working environment. The position and design of the cab pillars, the layout of the monitor and switch panel have been improved to ensure a wider field of view from the cab.

Hitachi Construction Machinery Americas Inc. takes visibility a step further with its Aerial Angle peripheral vision camera system. It provides a wide 270-degree bird’s-eye view of the machine’s immediate environment. Aerial Angle provides three cameras mounted on the rear of the machine. Operators can see both the left and right sides of the machine on the monitor inside the cab, providing visibility to the sides and rear of the machine.

Always focused on safety

Hitachi Construction Machinery Americas Inc. is always exploring new ways to increase safety on the job site. The latest innovation is an optional rear obstacle detection system on the ZW220-7 wheel loader. It offers rear object detection alerts to improve safety and help reduce potential damage on the job site.

The ZW220-7 also features emergency steering. The emergency electric pump delivers the necessary oil pressure for power steering even in the case of an emergency. This always allows normal steering, even if the engine fails.

Serviceability improves reliability and uptime

Design enhancements help protect critical components from the environment. An inner element of the engine air filter protects the engine from dust ingress while cleaning the outer element. Even the air conditioner is protected with a sealed internal filter that prevents intrusion of dust into the air conditioner unit.

Airborne debris can become an issue in many wheel loader operations, often leading to decreased cooling system performance. Hitachi Construction Machinery Americas Inc. addressed this with an intelligent automatic reversing hydraulically driven fan and wide-fin radiators which prevent clogging.

Daily maintenance has been simplified with easy-access filters and improved access to components.

Using telematic tools to monitor machine health also helps boost uptime. ConSite, which remotely monitors operational status and alerts owners and operators to upcoming maintenance needs, is making a leap forward.

ConSite Air is a new optional add-on that allows the wheel loader to be diagnosed remotely, as well as remote updates of the software. No matter where a machine is located, the servicing dealer can remotely diagnose issues that may arise, leading to increased uptime. A ConSite response team is on standby to rapidly resolve issues as they emerge.
