The WA470-7 scores high marks for economy and power at the same time. Komatsu’s Tier 4 interim technology ensures that the engine runs efficiently and saves fuel over the previous model. Selectable economy or power engine modes and SmartLoader Logic make sure the WA470-7 can be operated in the most efficient way. A large capacity torque converter with lock-up gives the WA470-7 tremendous power in the pile for filling the bucket and speed to climb ramps.
Features & Benefits
Komatsu SmartLoader Logic
The WA470-7 provides Komatsu SmartLoader Logic, a new engine control system. This technology acquires data from various sensors in the vehicle and controls the engine to yield enough torque for each work phase.
Large-Capacity Torque Converter
The newly designed power train has a large capacity torque converter for optimum efficiency. The WA470-7 has greater productivity in V-shape loading applications because the increased tractive effort does not require full throttle.
The newly designed large-capacity torque converter with lock-up is standard on the WA470-7. The lock-up function activates in 2nd, 3rd and 4th gears to give the loader a maximum travel speed of 38.3 km/h 23.8 mph.
Low Fuel Consumption
The WA470-7 has new features to reduce fuel consumption. These features enable further fuel efficiency by optimally controlling engine power and matching the Komatsu designed and produced high efficiency power train components and hydraulic system.
The Eco-guidance provides information on the monitor to help save fuel. The monitor displays messages in real-time during operation and on the exit screen when turning the key to shut off the engine.
Variable Displacement Piston Pump & CLSS
The variable displacement piston pump combined with the Closed-center Load Sensing System (CLSS) delivers as much hydraulic flow as the job requires, preventing wasted hydraulic flow. Minimized loss contributes to better fuel economy.
Operator Seat with EPC (Electronic Pilot Control) Levers
The work equipment control system has an EPC lever console integrated into the higher capacity seat and moves with the seat. The angle of the armrest is fully adjustable for optimum operator comfort.
Rear View Monitoring System
The operator can view the rear of the machine with a full color monitor that is located on the right side of the cab. This monitor can be always on or only on when the loader goes into reverse. Visual guidelines can also be added for more convenience.
Remote Bucket and Boom Positioner
The operator can set the bucket angle and remote boom positioner from the cab. Both upper and lower boom positions are adjustable in the cab with the push of a button.
New Mono Lever With Integrated 3rd Spool Control
The mono lever option has been redesigned for better ergonomics. When equipped with the optional 3rd spool valve, it allows the operator to control the 3rd spool with your thumb providing greatly improved operator comfort.
Large LCD Monotor
The LCD monitor displays various information of the machine such as ECO Guidance, operation records, and maintenance information. Since the LCD unit has a wide full color display area, it displays more information and is easy to read.
Swing-out Type Cooling Fan
The cooling fan swings out for cleaning. The coolers feature wider spacing of the cooling fins to reduce clogging.
