WA 450 Komatsu WA 450 Specifications & Technical Data (1988—1995)

High performance features for boosted production

Z-bar loader linkage ensure greater breakout force and provide a longer dumping reach and clearance, boosting productivity and facilitating access to dump trucks. They also contribute to excellent front views, making it easy to conduct leveling work.

High machine stability

High machine stability is assured by a center-pin-supported rear axle and large oscillation angle that keep the machine level on even the roughest surfaces. This, plus a long wheelbase, wide tread and large static tipping load, give Komatsu wheel loaders high stability for efficient digging/carrying operations. In addition, torque proportioning differentials (installed on models WA100 through WA470) minimize tire slippage and extend tire life.

Minimum maintenance for less downtime

Electronic display and monitoring system All important checkpoints are monitored and the operator is alerted through the sophisticated display panel in the event of a malfunction or emergency. The electric system for safety promotes foolproof operation. Full tilt hood: Employed on models WA300 through WA420. The engine hood can be tilted up to expose the engine, hydraulic components and transmission, making it easy to perform inspection and maintenance. Wet disc brakes are adjustment-free and have an extended service life. (Models from WA350 through WA800 are equipped with wet, multiple-disk brakes.) With these brakes, sure braking performance is maintained even when the machine is operated on muddy terrain. Sealed loader linkage pins need less maintenance. Bucket hinge and linkage pins are lubricated and protected by dust seals and cord rings. As a result, lubrication intervals are greatly extended. Especially, lubricated, sealed linkage pins installed on models from WA500 through WA800 greatly extend the maintenance intervals up to 2000 hours.

Operating comfort and easy control

Comfortable, easy-operation cab With a new design based on ergonomics, or comprehensive human engineering, this optional cab offers high operator comfort. Distinctive features include expansive tinted windows and ergonomically-arranged instruments, control levers and pedals. The cab is mounted on rubber pads for reduced noise and vibration. Responsive controls for high maneuverability The electrically-controlled transmission provides fingertip responsiveness and light-touch manipulation of speed control and direction change levers provided on the side of the steering column.

Adjustable operating configuration

Every operator can enjoy maximum comfort thanks to a smoothly-tilting steering wheel (tilts 100 mm or 4”) and fore/aft-adjustable operator seat. The optional oil-suspension seat is up/down and fore/aft adjustable with cushion hardness also varying according to the operator.
