WA480-8

Equipped with an EPA Tier 4 Final certified emissions regulations-compliant engine, the WA480-8 Wheel Loader is the latest addition to the wheel loader family. Combining higher production with lower fuel costs, improved operator comfort and enhanced serviceability, this machine is ideal for quarry, infrastructure and non-residential construction applications.

Features

Advanced Joystick Steering System (AJSS)

Allows steering and directional travel to be controlled by wrist and finger control to minimize operator fatigue in high duty cycle applications. AJSS allows for full speed travel speed while maintaining precise steering and control.

Automatic Digging System

Boom and bucket automatically raise, removing the need for operators to move levers to fill the bucket.

New Bucket Design

The newly designed bucket improves overall machine productivity. Generous curves on the side wall and wrap improve pile penetration and make it easy to fill. They also improve material retention in carry operations.

Load Meter (with 2V)

The Load Meter displays what material weighs in the bucket. Only available in two-valve/two-lever machines.

Optional Printer for Load Meter

The printer generates a ticket (or receipt) telling the operator the weight of the material deposited into the loading truck.

New Operator Seat with Electronic Pilot Control (EPC) Levers

A new air suspension seat provides enhanced support on rough roads and dampens machine vibrations, providing a more comfortable ride for the operator. An EPC lever console is integrated in the seat and moves with the seat. The angle of the armrest is fully adjustable for optimum operator comfort. A secondary F-N-R switch is incorporated in work equipment lever configurations. A heated seat is standard.

Tier 4 Final Engine

The Komatsu SAA6D125E-7 engine is EPA Tier 4 Final emissions certified and provides exceptional performance while reducing fuel consumption. Based on Komatsu proprietary technologies developed over many years, this new diesel engine reduces nitrogen oxides (NOx) by more than 80% when compared to Tier 4 interim levels.
