The Komatsu Tier 4 interim technology on the WA270-7 is designed to keep the operator working rather than having to stop and regenerate while saving up to 10% on fuel burned. The hydrostatic drive system on the WA270-7 gives the operator quick and powerful response, self-braking effect of dynamic braking and traction control. A multi-function mono-lever, rearview camera system with separate screen and heated, air ride suspension seat give the operator a comfortable and ergonomic work environment.
Features may include: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.
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.
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 limits the travel speed while still allowing for full hydraulic flow.
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.
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
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.
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.
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.
The operator can set the upper boom kickout from the cab.
