Komatsu SmartLoader Logic

Wheel loaders have different torque requirements depending on working conditions. Komatsu SmartLoader Logic reads data from various sensors and vehicle controls to precisely control the torque output. This lowers the torque output during less demanding work, saving fuel. And because its seamless to the operator, it operates without decreasing production.

Hydrostatic Transmission

The HST provides quick travel response and aggressive drive into the pile. Full auto-shifting eliminates any gear shifting and kick-down operation to allow the operator to concentrate on the digging and loading. The HST also acts as a dynamic brake to slow the loader. This prolongs the life of the wet disc brakes.

Variable Traction Control System

The new variable speed control system is designed to adjust the operating speed for each working condition. S-mode reduces tire spin in slippery or snowy conditions. Auto-mode automatically optimizes the tractive effort for various working conditions. Max traction provides the full, 100%, tractive effort.

Creep Mode

Creep mode limits the travel speed while still allowing for full hydraulic flow.

Heated Operator Seat with Air Suspension

A new higher capacity heated, air suspension seat with suspension damper is now standard. The arm rest angle is fully adjustable for optimum operator comfort.

Low Noise Design

Operator’s ear noise level : 70 dB(A)

Dynamic noise level (outside): 107 dB(A)

The large cab is mounted with Komatsu’s unique ROPS/FOPS viscous mounts. The low-noise engine, hydraulically driven fan, and hydraulic pumps are mounted with rubber cushions, and the cab sealing is designed to provide a quiet, low-vibration, dustproof, and comfortable operating environment

Rear View Monitoring System (standard)

The operator can view the area directly behind the machine with a full color monitor that is located on the right side of the cab. This monitor can be set to be always on or only on when the loader goes into reverse. Visual guidelines can also be added to show the machine's travel path.

Electronically Controlled Suspension System (ECSS)

The Electronically Controlled Suspension System (ECSS) or ride control system uses an accumulator which absorbs some of the shock in the boom arm, giving the operator a much smoother ride. This reduces operator fatigue and reduces material spillage during load and carry operations. ECSS is speed sensitive, meaning that the boom won’t move during stationary digging. ECSS is standard on the WA270-7.

Multi-Function Mono Lever

The multi-function mono lever with EPC control for 3rd spool is standard. It includes a forward-neutral-reverse switch for quick and easy travel. Third spool attachments can be set to continual or proportional control via the monitor panel allowing the operator to control the boom, bucket and attachment all with a single lever.

Remote Boom Positioner

The operator can set the upper boom kickout from the cab.

Full Side-Opening Gull-Wing Engine Doors

The large gull-wing type engine doors are operated with low effort assisted by gas springs. The doors open in two steps for easy access to maintenance points. Large steps and hand holds are provided on each side of the frame to help access.

Swing-out Type Cooling Unit

The large capacity cooling unit swings open for cleaning. It features wider spacing of cooling fins to reduce clogging.

Manual Stationary Regeneration

Under most conditions, active regeneration will occur automatically with no effect on machine operation. In case the operator needs to disable active regeneration or initiate a manual stationary regeneration, this can be easily accomplished through the monitor panel.A soot level indicator is displayed to show how much soot is trapped in the KDPF.
