Since 1965, we have developed a reputation for delivering quality and proven gear systems for processes in mining, shipping terminals, wind, cement, aggregate, pulp and paper and forestry.

On the mining side, we have vast experience supporting transmission rebuilds on rope shovels, hydraulic shovels, hard rock drills, apron feeder drives, and conveyor drives at Canada’s key mining operations. Using our extensive expertise, we’ve made countless efficiency improvements on swing, propel and hoist transmissions for mining equipment like the CAT 7495 and P&H rope shovels.
