CHARLOTTE, North Carolina – Champion Motor Graders has a new line of low-profile, compact graders specially developed for work in underground mines.

The new M786 mine grader is a modified version of Champion’s popular all-wheel drive C86 C-Series compact grader. The low-profile cab has been lowered to give the M786 a maximum height of 2.13 metres. The grader is also reinforced in critical areas to withstand the added shock loads and long duty cycles of mine operations.

The greatest challenge to Champion engineers was to lower the grader height while maintaining adequate clearance for its many moving parts and assemblies. Particular attention was paid to the placement of the final drive on the M786 and to fine-tuning the wheelbase. Additional considerations included the mine’s narrow workspace, subjecting the machine to impacts on the sidewalls, as well as the shocks of hitting large rocks and the need for the grader to run in reverse for extended distances. The M786 is also designed to accommodate “mine ready” specifications such as fire suppression or special braking requirements.

The Champion grader line-up includes seven basic models with operating weights from 5.44 to 10.88 tonnes, with the full range of single-axle, tandem and all-wheel drive systems. Learn about them at www.ChampionMotorGraders.us.
