Komatsu's WA100-5 features simplicity and safety

As with the WA65-5 loader, Komatsu's first release in the compact Dash 5 range, the new WA100-5 wheel loader is a hydrostatic transmission machine providing easier access for service and maintenance than competitive machines, while still being easy to transport, the company says.

Powered by a tier II-compatible Komatsu S4D95-LE3 diesel rated at 61.5 kW, it has an operating weight of 6.86t and bucket capacities of 1.2 to1.8m3.

When fitted with the standard 1.2m3 bucket, it can lift 2.2t, the most in its class, while lifting capability with forks is 2.9t, also a class-leading figure.

The WA100-5 replaces the WA95-3 and according to Komatsu Australia's national utility sales and marketing manager Carl Grundy, will achieve similar acceptance as the WA65-5 released in 2005.

“In addition to performance and productivity advantages, it's been designed to be easy to service, while the hydrostatic transmission and all-round visibility make it simple and safe to operate.”

Key features of the WA100-5 include:

Large air-conditioned cab with substantial glass area and ergonomic design;

A Delta boom, elevated operator cab and sloping rear engine bonnet combined with a narrow tail;

Rear-axle oscillation for improved operator comfort, stability and better digging performance;

Extra-long wheelbase combined with Komatsu's electronically-controlled suspension system (ECSS);

Reversed Z-bar linkage combining parallel lift with high breakout forces through the lift cycle; and

A compatible with other manufacturers hydraulic quick coupler as standard.

The WA100-5 has been designed to provide easy access to the engine, drivetrain and hydraulics, through a tilt-up cabin. This eliminates the need to dismantle engine bonnets or remove the operator's cabin.

Daily maintenance has also been simplified, with the longitudinally-installed engine allowing access to all sides of the engine block, while also giving better weight distribution for increased payload capacity and machine stability.

All filters, fillers and gauges are easy to reach from ground level, while the radiator is free-standing for better cleaning access. All major service intervals are set in 500-hour increments.

A cab-controlled reversible fan, allows the operator to ensure key components stay cool, even in very dusty environments.

Travel time between jobs is also minimised, with the WA100-5 able to travel at up to 30km/h.

“As with the WA65-5, we see this as being suitable for many different applications and industries, from local government, landscaping, larger nurseries and civil contracting through to the general hire and rental market – but in situations where customers need more capacity and production,” Grundy said. “The hydrostatic drive and ease and safety of operation, makes it ideal for dry hire or sales loader applications, where machines are frequently driven by many different operators.
