LOAD & HAUL T e 28 tonne capacity TA300s will
work two shifts per day hauling coal from the pit to the storage yard. T e coal is then transported to a power plant by on-highway trucks or rail. Situated 9km northwest of Bugojno, the Gracanica mine measures 2,000m by 800m. “T e TA300s are a welcome addition to our fl eet, joining seven TA30s already working on the mine,” says Eldin Mustajbegovic, head of mechanical maintenance at Rudnik Uglja Gracanica. “T e trucks are fuel effi cient and have been extremely productive, so we’re looking forward to putting the new TA300s to work.” T e TA300 is equipped with independent front suspension to enable excellent traction control, making it ideal for the rocky Bosnian and Herzegovina coal mine. T e dump truck has a maximum payload of 28 tonnes and 370hp engine power. T e TA300s are being supplied by Terex Trucks dealer Lager.
Rigid revolution In August, Hitachi Construction Machinery – Americas announced the launch of two rigid-frame haul truck models designed for use in large- scale mining operations. T ese are the EH3500AC-3 (nominal payload with standard equipment of 200 tons, target gross machine operating weight of 709,888 lb), and the EH4000AC-3 (nominal payload with standard equipment of 243.6 tons, target gross machine operating weight of 846,575 lb). T e two rigid-frame haul truck models are equipped with an advanced AC-drive system that was developed with Hitachi Group technologies employed in conventional models. Improvements include various sensors that provide information on drive conditions. T e result is the Hitachi Drive Control System that reduces tyre slippage on acceleration and tyre
lock-up during braking, and prevents chassis oscillation in a front-rear direction and tyre skid while steering. In addition, to satisfy the request of its customers worldwide, Hitachi is giving customers outside of North America a choice between engines from two diff erent companies. T is option is also available for the EH5000AC-3 rigid haul truck, which was launched in February 2013. T e release of these two rigid- frame haul truck models completes the lineup for the EH AC-3 series of haulers equipped with an AC-drive system. Along with the company’s ultra-large hydraulic excavators, for which it boasts a high market share, Hitachi plans to supply these rigid haul truck models to contribute to the improvement of productivity at mines around the world.
Motion activated Finally, in news on the monitoring side of load & haul operations, Motion Metrics recently announced a partnership with Komatsu Brazil. T rough this arrangement Komatsu Brazil will off er Motion Metrics systems for all Komatsu equipment in addition to all shovel, excavator and loader models to support mines throughout Brazil. ●
