Komatsu Australia says its soon-to-be released WA500-7 wheel loader will increase productivity while significantly reducing fuel use, emissions and running costs.
The new model has an operating weight of over 34 tonnes and a huge bucket capacity of over 6 square metres. The big loader is powered by a Komatsu diesel engine designed to meet US Tier 4 Interim/EU Stage 3B emissions targets.
The engine contains a number of improved tech features such as a variable geometry turbocharger, cooled exhaust gas recirculation system, high-pressure common rail fuel injection and a diesel particulate filter.
The machine also has a range of automated features aimed at keeping efficiency high and downtime low, Komatsu says.
The SmartLoader Logic system automatically monitors information received from sensors placed throughout the driveline on load and working conditions. It continuously modifies engine torque to ensure that no excessive power is used, keeping fuel use down.
Fuel efficiency is further enhanced by an automatic idle shutdown, a dual-mode engine power select system, variable displacement piston pumps and closed-centre sensing hydraulics that prevent loss from wasted hydraulic fuel.
“Reducing operating costs is front of mind for Australian construction, materials handling and quarry businesses and the Dash 7’s technology and efficiency react to market needs for cleaner, greener machines with exceptional performance,” Komatsu national business manager Richard Feehely says.
“While increasing productivity, the new range of wheel loaders takes a multi-tiered approach to reduce fuel consumption. The new range will see customers extract more from their investment,” he adds.
The operator’s cab has been given an upgrade as well, with a heated ergonomic seat and telescopic steering wheel. The cab’s dashboard contains a rear-view monitoring system and large LCD display for machine information.
Maintenance has been streamlined with swing-out fenders that allow access to the ‘gullwing’ engine bay doors for daily maintenance. A large-capacity cooling fan can be automatically reversed to clear debris, eliminating the need to do this manually.
“Comfort and ease of access is key to operator effectiveness and the Dash 7 is the latest word on ensuring the people who use Komatsu machines are as happy as the people who own them,” Feehely says.
