LOAD & HAUL When asked how mines can benefi t
from using electric LHDs rather than their diesel-powered counterparts, Sandvik’s Jarkko Koskinen has a comprehensive answer to hand. “Generally speaking, mines benefi t in a number of ways,” he begins. “Firstly, via reduced ventilation costs (no harmful diesel exhaust emissions to ventilate). Next is through the cost of energy: globally many locations enjoy lesser costs of energy in electricity versus diesel fuel. T ere is also no need for logistics (diesel transport to mine and within mine), which further saves money. On a technical level, EHS mean no harmful diesel exhaust emissions, and less local heat emitted from an electric LHD versus a diesel one.”
Commenting on the merits of this specifi c machine, Qin Zhong,
Sandvik’s L&H product support manager for China, says, “T e improved powertrain and powerful, responsive electric motor enables better penetration rates and effi cient loading of the 2m3
bucket.”
T e vehicle control and management (VCM) system monitors all loader parameters, including tramming speeds, operating temperatures and pressures, to expedite troubleshooting and minimise unscheduled downtime. An operator’s compartment in
the rear frame and an optional fully enclosed cabin, which Sandvik says is unique for this size class, enhance operator safety and comfort, which means improved performance and productivity.
Steering the right course T e latest announcement from another industry giant, Cat, relates to its new series of loaders (skid steer, multi-terrain and compact track). T ese feature standard advanced display, enhanced operating capacities, reduced emissions and a sealed engine compartment T e new Cat 272D2 Skid Steer
