Komatsu adds two new Dash 7 compact loaders to lineup

Two new compact Dash 7 wheel loaders designed to lower operating costs and improve safety have joined Komatsu’s lineup — the 5-5.4 tonne WA70-7 and the 6.9-7.2 tonne WA100M-7.

While the WA70-7 has a Tier 3-compliant Komatsu ecot3 4D95LWE-5 diesel engine rated at 36.9kW, the WA100M-7 boasts a Tier 4 Interim (EU Stage IIIB) Komatsu SAA4D95LE-6 engine rated at 66kW. Both have hydrostatic transmissions.

Komatsu Australia utility national sales manager Carl Grundy says the Tier 3 engine on the WA70-7 “provides top class performances and guarantees fuel efficiency, while keeping exhaust and noise emissions well below Australian limits”.

The WA100M-7’s Tier 4i powerhouse builds on this platform, Grundy adds: “With this new engine, we have leveraged our leadership in technology and innovation to design an environmentally friendly engine that decreases fuel consumption by approximately 10 percent, compared to the WA100M-6, while significantly lowering diesel emissions.

“Our Stage IIIB system includes Komatsu’s Variable Flow Turbocharger (KVFT) and an EGR (exhaust gas recirculation) valve, resulting in better precision and air management as well as longer component life.”

Both wheel loaders come with Komatsu’s KOMTRAX remote monitoring system as standard.

KOMTRAX constantly monitors a wide range of critical operating parameters — such as location, fuel consumption, dashboard cautions, attachment working hours and load frequency — and alerts the owner and Komatsu service personnel of any potential issues.


WA70-7 task master

“We have designed the WA70-7 to be able to perform an unrivalled variety of tasks with the highest levels of productivity and reliability,” Grundy says. “It comes as standard with a Komatsu quick coupler and third auxiliary hydraulic line for the quick and easy changeover of attachments, such as a 4:1 bucket, sweeper unit or pallet forks.”

The WA70-7, like its Dash 6 predecessor, features Komatsu’s ‘Easy Fork’ bucket linkage system, which the company says combines the parallel lifting movement of heavy payloads using forklift attachments with the high breakout forces of Z-bar type systems for digging and material shifting.

The safety aspect of the earthmover has been improved, with standard features including an engine shutdown secondary switch, seatbelt caution indicator, backup alarm and reversing light.

Grundy says the wheel loader has been designed for maximum comfort and ease of operation.

“The roomy cabin is the largest available for this class of loader, with standard features including an adjustable steering column and seat, a heated rear window, 360-degree visibility and ample storage room for personal belongings,” he says.

“We’ve also improved maintenance and serviceability, particularly with our unique tilting cab that gives quick and easy access to all major components – allowing service to be performed safely, easily and quickly.”

Brief specs are: Operating weight, 5.035-5.38 tonnes; bucket capacities, 0.75-1.25 cu m; bucket breakout, 4100kgf (0.85 cu m universal bucket); static tipping load, full turn, 3650kg; maximum speed, 20km/h.


Versatile WA100M-7

Grundy says the WA100M-7 is designed to be a highly versatile and flexible loader, suitable for a wide range of utility, earthmoving, construction, building and maintenance applications

“Optimised for tough construction applications, the WA100M-7’s powertrain delivers high torque even at low engine revs, has high rimpull and has plenty of power in reserve for the most difficult ground conditions,” he says.

A fully automatic, hydrostatic transmission sends power to all four wheels, and an optional 10 percent differential lock can be applied to the loader’s two LSD (limited slip differential) axles for additional tractive force.

“It features a hydraulic quick-coupler and delta-style boom for optimum visibility to the quick coupler pins and across a wide range of attachments,” Grundy says, as well as the ‘Easy Fork’ bucket linkage system featured on the WA70-7.

Cabin features include an enlarged two-door cab with improved headroom and additional steps, large glass surfaces on the doors, and a heated rear window.

The new cab design also contributes to a lower centre of gravity and, in turn, to a stable, comfortable and quiet work environment.

Machine functions are controlled via a PPC multifunction lever, including electronic proportional control for the optional third hydraulic circuit for simple attachments control. Travel control is made easier though a forward-neutral-reverse switch.

Like the WA70-7, the WA100M-7 has a tilting cab for easier maintenance and serviceability, while a redesigned engine hood opens wide for quick daily inspections, and all electronic equipment is protected behind a maintenance cover inside the cab.

A wide core radiator with an optional reversible fan is now standard.

Brief specs are: Operating weight, 6.925-7.23 tonnes; bucket capacities, 1.05-1.8 cu m; bucket breakout, 7420kgf (1.25 cu m universal bucket); static tipping load, full turn, 5030kg; maximum speed, 30km/h.
