Pit Operations

Off-highway  (OHV) rigid dump trucks play an essential role in high production mining operations.  Most haul truck capacities range from 40 short tons to 400 short tons.  Recently, ultra-class haul trucks with a capacity of 300 short tons or greater have become the main stay of mining.   Diesel electric haul trucks require specialized electrical and mechanical services for individual components and complete systems.

We have the in-house expertise to build a haul truck from the ground up and to service all of the electrical rotating components.   Wheel motors such as the GE 787, GE 788, GE B25, GE GDY106 and GDY108, alternators, grid blowers are a specialty.   We have both in-house and strategic partnerships to service engine modules, struts, dump bodies and specialized components all the way down, and including, the truck frame.

Electric rope shovels play a major role in mining for overburden removal.    Shovels consist of a revolving deck with a power plant, a counterweight, boom, dipper handle and bucket.  Bucket capacities range from 8 cubic meters to 80 cubic meters.  Uptime is critical for a shovel because it plays a crucial role in mine production.

Our services and repairs for shovels involve everything from shovel dismantle and erection in the field to repair of individual component.    Booms, dipper handles, side frames, tracks and rollers, transmissions, motors, gear boxes, hoist drums, point sheaves and blocking are names of just a few of the components we service both, in the shop and in the field.  We understand the importance of uptime.

A dragline is a massive excavator used generally in coal mining to remove large amounts of overburden.   These machines have components built on a very large scale to withstand extreme duty cycles.  Whether called upon to service existing draglines, to relocate and refurbish used draglines or to design and improve existing components, we have solutions to keep draglines in motion.
