Expandable Undercarriage

The PC18MR-3 can pass through narrow space due to narrow width and undercarriage can be expanded for good stability during excavation.

Tight Tail Swing

Operator is able to focus on the work in front of them and worry less about a rear swing impact, even in confined areas with only an 80mm 3" projection over the tracks.

Closed-centre Load Sensing System

When two or more actuators are operated simultaneously, the pressure-compensated CLSS system ensures each actuator works according to its control input, regardless of the size of the load. This gives the operator precise control at all times.
