In 2010, Atlas Copco presented the next generation of underground trucks with the new model Minetruck MT42. This high-speed 42 tonne articulated truck has been designed to maximize productivity as well as provide increased safety and excellent operator comfort in underground haulage applications.
The Minetruck MT42 is powered by a fuel efficient, low-emission Cummins QSX15 520 hp EPA Tier 3/Stage IIIA engine. The transmission has eight forward and two reverse gears and features a self-diagnostic system for rapid troubleshooting.
Operator comforts in the standard ISO ROPS/FOPS certified cabin include an air suspended forward-facing seat, a clear, multifunction display monitor, air conditioning and a trainer’s seat. The operator’s sound exposure is below 80 dB (A) in the cabin.
Front axle suspension further contributes to operator comfort, while also allowing greater speeds on mine roadways. The articulated steering increases maneuverability and allows agile cornering, while the dump system can discharge a full load in just 13 seconds. Rear facing cameras, one backup camera and one loading camera covering the box, complement the operator’s view from the cabin.
The truck’s brakes are spring applied, hydraulic released (SAHR) – the safest in the industry. SAHR brakes eliminate the need for a separate parking brake, are low maintenance and provide extended service life. A service bay on the side of the truck allows easy access to filters, valve blocks and service points for daily maintenance and the cabin can be hydraulically tilted to expose the engine bay.
