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. Engine torque requirements for a wheel loader vary depending on working conditions. For example, the loader requires higher torque for digging in V-shape loading, but less torque when traveling with an empty bucket. This technology limits the engine torque during less demanding work, therefore saving fuel. Komatsu SmartLoader Logic functions automatically and doesn’t interfere with operation, saving fuel without decreasing production.

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 improved hill climbing ability allows the WA470-7 to up-shift gears faster because of improved acceleration. The WA470-7 can achieve higher gear ranges and maintain higher travel speed when working in load-and-carry applications. In most applications, production is increased and fuel consumption is reduced, resulting in improved fuel efficiency.

Enhanced Lock-Up

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. The large capacity torque converter with enhanced lockup is effective for both load and carry applications, and V-shape loading which uses lower gears. The enhanced lock-up reduces the clutch engagement shock by controlling engine torque with Komatsu SmartLoader Logic improving operator comfort. The enhanced lockup combined with Komatsu SmartLoader Logic results in lower fuel consumption and higher travel speeds in load and carry and even some cycle loading applications.  

Low Fuel Consumption

Komatsu added many new features on the WA470-7 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.

Eco-Guidance

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. This function can be controlled through the monitor. The operator can view Eco-guide and fuel consumption through the monitor as well as through KOMTRAX.

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. An F-N-R switch is now incorporated in dual and three lever configurations as well as the optional monolever configurations. A heated seat is now standard.

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. The bucket positioner can memorize three horizontal settings, allowing the operator to easily change attachments without having to reset the bucket position. In each horizontal setting, the operator can adjust the setting with the switch in the cab. This can help save the operator time when changing attachments.

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. The 3rd spool valve can be operated in either continuous or proportional flow modes. The mono lever also includes a F-N-R switch. 

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. For example, the “Operation Records” menu displays various records of the actual working hours, average fuel consumption, idling hours, and E mode operation ratio, as well as other features. These records are displayed in the form of daily data and time period data. Data can be displayed in 25 languages to support operators around the world. The controls for the automatic air conditioner are integrated into the LCD monitor panel to allow the operator to easily and precisely set the cab atmosphere. The monitor clearly displays abnormality codes to alert the operator. These codes are stored for trouble shooting. The monitor also provides for advanced monitoring of system parameters through the Service Mode to aid in troubleshooting and reduce downtime.

Swing-out Type Cooling Fan

The cooling fan swings out for cleaning. The coolers feature wider spacing of the cooling fins to reduce clogging.
