Performance and Versatility

Fast, powerful digging, through smooth responsive hydraulics, ensures that the Cat C Series CR machines deliver the productivity that customers demand. Load sensing hydraulics optimize flow for smooth powerful performance and increased fuel economy. 1 way (hammer) and 2 way (auger) auxiliary lines including quick connections are fitted as standard. Optional 2nd auxiliary circuit increases work tool versatility, allowing operation of rotating work tools. Dozer float function enables more efficient clean up and landscaping operations. Choice of standard or long stick enables better matching of machine to application. High rotation bucket angle combines good spoil retention and flat back trench characteristics. Additional counterweight allows machine configuration to match the work tool and application.

Comfort and Ease of Operation

Cab and canopy options are available on the C Series CR. Compact radius design gives greater machine versatility and 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 performed without having to worry about the back of the machine. Automatic two speed travel function optimizes on site travel speed with the required tractive effort. Joystick mounted auxiliary and boom swing controls give finger tip control of machine functions and an uncluttered floor. Optional air conditioning or fan and sun blind package offers further operator comfort.

Low Operating Costs

Robust, reliable and easily serviced are key attributes of the C Series CR design. Swing out rear door and side hood provide excellent access to regular service and maintenance points. Radiator and oil cooler placed side by side for easy cleaning. Protected front linkage lines are routed out of harms way above the boom and stick. End dampening on both boom and stick cylinders reduces shock loading, increasing component life and improving soil retention when loading at height. Liner bearings in the swing casting deliver longer component life and reduced parts replacement costs. 100% pilot controls maintain “as new” machine control and eliminate the need for linkage and cable maintenance. 500 hour oil and filter change period reduces operating costs and machine down time.
