Overview

Longwall moves represent an enormous challenge to underground transportation logistics. Caterpillar offers a full range of roof support carriers to meet the needs of efficient longwall moves. With an increased lift capacity of 45 tonnes (50 ton), the SH650 can handle almost any piece of longwall equipment in a move. In addition to enhanced traction and maneuverability, the SH650 offers improved range of motion of the lift, allowing easier load engagement.
