Sliding Cab Door

The sliding door system offers good access and maintains the machine's compact dimensions to reduce the risk of damage .

Fully Pilot Operated Controls

Pilot operated controls on all services including travel levers and dozer function ensure that "as new" levels of controllability are maintained throughout the machine life .

Automatic Two Speed Function

Improves machine maneuverability around the job site. Increased productivity by balancing high speed travel requirements with controllability .

Joystick Mounted Auxiliary and Boom Swing Functions

The new joystick mounted position of these functions gives fingertip control and a clear cab floor .

Compact Radius Design

Compact radius design gives greater machine versatility and the capability to work within confined areas. The radius of the upper body stays within the width of the undercarriage so the operator can concentrate on the work being done without having to worry about the back of the machine .

High Level of Standard Comfort Features

Reclining suspension seat, power point, adjustable wrist rests and a cup holder are standard features on the Cat C CR machines .
