Original Press Release:
Komatsu America Corp. Launches New WA270-7 Wheel Loader
New Machine Powered by Tier 4 Interim Engine Technology
Rolling Meadows, IL—Komatsu America Corp.today introduces the WA270-7 wheel loader. With a net horsepower of 149 hp (111 kW), the WA270-7 is powered by a Komatsu SAA6D107E-2 engine, which is EPA Tier 4 Interim and EU Stage 3B emission certified. Built upon a proven Tier 3 engine platform, Komatsu has leveraged its leadership in technology and innovation to design a more environmentally friendly engine withfuel consumption decreased by up to10 percent, compared to the WA250-6.
The WA270-7 replaces the WA250-6 and WA250PZ-6. Weighing in at 28,836 pounds (13,080 kg), the new wheel loader features improved efficiency, lower fuel consumption, improved operator comfort, and enhanced serviceability to maximize productivity while lowering operating costs*.
ONE MACHINE FOR ALL APPLICATIONS
The WA270-7 utilizes the versatile Parallel Z-bar (PZ) loader linkage. This linkagecombines theadvantages of a parallel lift linkage for pallet handling and high tilt forces for large attachments. The PZ linkage also offers large breakout force and a 10% increase in lift force which not only make bucket filling quicker and easier but also improves digging performance.
New features of the WA270-7include:
• EPA Tier 4 Interim and EU Stage 3B Emission Certified Engine
Built upon proven Tier 3 technology, the SAA6D107E-2 engine provides lower emissions while also lowering fuel consumption. The Komatsu Tier 4 Interim engine uses an advanced electronic control system to better manage air-flow rate, fuel injection, combustion and exhaust after-treatment to optimize performance, reduce emissions, reduce fuel consumption and provide advanced diagnostic capability.
Komatsu has leveraged its leadership in hydraulic technology to develop a hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve. This results in better precision and air management as well as longer component life. The Komatsu Diesel Particulate Filter (KDPF) has an integrated design that will not interfere with daily operation yet keeps the operator aware of its status. This smart system enables a high percentage of passive regeneration.
The WA270-7 also features Komatsu SmartLoader Logic, which provides optimal engine torque for the job required. Komatsu SmartLoader Logic helps save fuel by automatically decreasing engine torque when the loader isn’t working as hard, such as when it is driving with an empty bucket. Komatsu SmartLoader Logic functions automatically and doesn’t interfere with operation, saving fuel without decreasing production.
• Responsive Hydrostatic Powertrain System
Now in its 3rd generation, the Komatsu hydrostatic (HST) drive train features increased pump capacity for higher efficiency and responsiveness. The dynamic-braking effect of the HST drivetrain slows down the machine when the accelerator is released. Additionally, brake wear is practically eliminated. Control is also enhanced which is especially important when working in tight places.
The electronically controlled HST drivetrain features Komatsu Traction Control System which helps facilitate operation in soft or slippery ground. Simplified traction controls feature AUTO and S-Mode. Variable Speed Control (VSC) allows the operator to set a maximum speed up to 8.1 mph for applications such as mowing or broom use. For slower speeds, the creeping speed range sets a maximum speed up to 2.5 mph.
• Enhanced Operator Environment
The new cab provides a more comfortable and quieter work environment. For improved visibility, the front glass has been lowered and the dashboard has been redesigned.A new redesigned seat-mounted right hand console has a multi-function mono-lever with proportional control for the integrated 3rd spool. An auxiliary input has also been added to connect an MP3 player or other device along with two 12-volt ports that have been incorporated into the cab.
The high-resolution 7” LCD monitor features enhanced capabilities and displays information in 25 languages for global support. Using the monitor, the operator can easily modify settings for items such as the new Auto Idle Shutdown or the auto-reversing fan.Operators can also check operational records, such as working hours, fuel consumption, monitor the KDPF soot load, or check when the next maintenance interval will occur. Additionally, the monitor offers the operator the option of using the ECO Guidancefunction, which will provide operational tips to reduce fuel consumption. A high-resolution back-up camera is standard along with a separate monitorthat is mounted on the right hand side of the console for operator convenience.
• Customer peace-of-mind is standard with Komatsu CARE®
Komatsu remains focused on lowering the customer’s ownership costs by engineering machines with increased fuel efficiency and productivity. To further reduce owning and operating costs, Komatsu CARE® complimentary scheduled maintenance is standard on all WA270-7 wheel loaders for three (3) years or 2000 hours(whichever occurs first). Services are performed by factory-certified technicians using only Komatsu genuine parts and fluids. Also included are two complimentary KDPF exchanges at 4,500 hours and 9,000 hours within the first five (5) years.
• Convenient Maintenance and Serviceability
The WA270-7 provides convenient service access to reduce downtime. The new wheel loader has increased cooling capacity, wider coolerfin spacing and a standard auto-reversing fan to help keep the radiator clean.The machine is equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System), which provides enhanced diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities. EMMS also continuously monitors many critical systems, as well as the planned maintenance schedule, and provides troubleshooting assistance to minimize diagnosis and repair time.
The WA270-7 is equipped with the latest KOMTRAX„Â¥ technology, which is fully integrated with Komatsu’s Tier 4 technology. KOMTRAX sends machine operating such as operating hours, fuel consumption, location, cautions and maintenance alerts information to a secure website utilizing wireless technology.The KOMTRAX fleet monitoring system increases machine availability, reduces the risk of machine theft, allows for remote diagnosis by the distributor, and provides a wealth of other information to help drive business efficiency and productivity.
