Komatsu has upgraded its popular HD1500-7 mining truck with the release of the HD1500-8 mechanical drive dump truck.
The manufacturer says the 142 metric-tonne capacity hauler is designed to reduce cost per tonne through such features as highest payload in its class, faster cycle times, improved fuel efficiency, longer component life and enhanced maintainability.
“Our new HD1500-8 truck will further build on the success the HD1500-7 has had in Australia,” Komatsu Australia national product manager, mining, Scott Harrington said.
“It’s a completely new, redesigned truck, developed using principles developed by the Earth Moving Equipment Safety Round Table (EMESRT) to ensure high standards of safety and harm minimisation.
“This new truck builds on the performance and reliability characteristics of the HD1500-7, as well as incorporating technological advances from our proven HD785-7, such as the Komatsu Traction Control System.”
Komatsu estimates the new model will provide a further 6 per cent cost per tonne advantage compared with the HD1500-7.
Power comes from a 16 cylinder Komatsu SDA16V159-3 engine, based on the Cummins QSK50 Tier 2 diesel (also available in fuel-optimised calibration), rated at 1175 kW gross – a 6 per cent increase in power over the 12-cylinder Komatsu SDA12V160 powering the HD1500-7.
A key element in the truck’s improved fuel efficiency, higher productivity and increased safety is a revamped transmission system which offers a seven-speed automatic transmission with selectable reverse gear ratio.
This is combined with the electronically controlled technologies introduced in the HD785-7 to optimise operating efficiency.
The HD1500-8 includes a payload monitoring system (PLM) which assists in managing the payload of each haul cycle, as well as analysing production volumes and working conditions.
Brief specs of the HD1500-8 are: Payload capacity, 142 tonnes, body capacity (SAE heaped 2:1), 78 to 94 cu m; engine, Tier 2 or fuel-optimised Komatsu SDA16V159-3 engine rated at 1175 kW gross; maximum travel speed, 56.5 km/h; loading height, 5070 mm for 94 cu m body or 4750 mm for 78 cu m body; hoist raise/lower times, 13.5/12.5 seconds.
