Cat C6000 Specifications

Basic Information

The Cat C6000 is a high-performance Class IV internal combustion cushion tire forklift built for demanding indoor applications requiring 6,000 lb lifting capacity. Powered by a Nissan K25 engine with multi-port fuel injection on gasoline models or throttle-body fuel injection on LP gas models, it provides responsive power delivery and operational efficiency. Operators benefit from a thoughtfully designed compartment with cowl-mounted hydraulic levers, a two-pedal brake system, and a memory tilt steering column that enhances comfort during extended shifts.

The single-speed powershift transmission with hydraulic accumulator ensures smooth directional changes, while the heavy-duty cast drive axle and hydrostatic power steering contribute to its reputation as a durable, productive workhorse in warehouse environments. Additional features include an engine protection system, high-output direct-drive hydraulic pump, and a 48 in high load backrest extension.
