Komatsu’s Dash-8 loaders feature latest technology
New Dash-8 loaders feature all the latest technology developments
Komatsu Australia has added two new wheel loader models – the WA270-8 and WA320
8 – to its Dash-8 range. Both feature Komatsu’s fourth-generation hydrostatic drive transmission system and its versatile parallel Z-bar (PZ) linkage system, which combines high breakout forces with parallel lift throughout the lifting cycle.
The WA270-8 replaces the WA250PZ-6 and has a 111kW Komatsu SAA6D107E-3 engine, offering bucket sizes from 1.9-2.7 cubic metres. The WA320-8 replaces the WA320PZ-6 and is powered by a 123kW Komatsu SAA6D107E-3 with bucket capacities from 2.3-3.2 cubic metres. Both are configured to Tier 4 Final emissions standards.
Komatsu Australia says it skipped the Tier 4 Interim-equipped Dash 7 range, going straight from Dash 6 to 8 to ensure customers are getting the latest in emissions and fuel-efficiency technology.
“These latest wheel loaders incorporate all the technology developments introduced in both the Dash 7 and Dash 8 upgrades, including improved performance and safety, reduced fuel consumption, superior operator ergonomics and enhanced maintainability,” Komatsu Australia national business manager Richard Feehely says.
The Dash 8 models have increased straight and full-turn static tipping loads (STL) for improved productivity and safety. The WA270-8 has a fullturn STL of 8930kg (2.3-cubic metre capacity GP pin-on bucket) and the WA320-8 9780kg (2.8-cubic metre capacity GP pin-on bucket).
“These new loaders deliver significantly lower costs per metre of material moved than their predecessors,” Feehely says.
The Dash 8 loaders have redesigned cabins aimed at improving visibility and comfort while reducing noise. The cab’s air-suspension seat dampens machine vibrations.
“The seat, along with steering wheel, is fully adjustable for optimum comfort and control,” Feehely adds. “In-cab noise levels at the operator’s ear have been reduced, down to 68dBA on both, a significant reduction on their predecessor.”
