The Caterpillar® 854K wheel dozer incorporates innovations to lower engine emissions and boosts fuel efficiency, improves reliability and serviceability, and optimizes operator efficiency and comfort. Specifically, the 854K uses a Cat C32 engine and a new radiator with improved heat transfer capabilities. A variable speed demand fan aids efficiency. For the operator, a new, larger cab includes a trainer's seat, and a new low-effort joystick controls all blade functions.

The 854K replaces the 854G and retains the best features, including the impeller clutch torque converter for superior operator control and optimum power to the ground, lockup clutch for direct drive efficiency, and STIC™ control system for reduced steering and transmission control effort.

The largest wheel dozer in the Caterpillar line, the 854K is engineered for demanding work in large dozing applications, such as mining and bulk materials handling, where mobility increases productivity. Operating weight is 217,128 pounds and blade capacities range from 33.1 to 58.2 cubic yards.

The Cat C32 engine, rated at 800 net horsepower features ACERT Technology, an exclusive Cat emissions-reduction solution. The 12-cylinder engine is a V configuration with displacement of 1,960 cubic inches.

A combination of technologies makes the Cat C32 engine clean, quiet, fuel efficient and compliant with US EPA Tier 2 standards and EU Stage IIa standards. The C32 also offers 500-hour oil change intervals for reduced maintenance costs and the optional oil renewal system (ORS) can reduce the need for oil changes even further.

The next generation modular radiator (NGMR) is a Caterpillar technology that improves serviceability and increases cooling efficiency. The copper core provides greater heat transfer rates when compared to steel and the new copper fins are copper brazed for high joint integrity. The header plate, tank and side sheets are brass. The modular core allows removal of a single module without removing the entire radiator resulting in reduced downtime and lower repair costs.

The 854K also features a true demand fan for enhanced fuel efficiency and quieter operation. The system adjusts the speed of the fan based on the coolant temperature.

The drive train features the impeller clutch torque converter (ICTC) which allows the operator to modulate rimpull efficiently using the left pedal for smooth operation and extended tire life. The ICTC works in conjunction with the proven rimpull control system, which enables the operator to adjust maximum rimpull by using an in-cab switch. Matching rimpull to the application extends tire life by improving traction in slippery or rough conditions. And throttle lock allows the operator to preset the engine speed and subsequently to concentrate on other control functions. The results are faster cycle times and improved fuel efficiency.

Operator station promotes efficiency

The cab is spacious and provides superior visibility to the work area. Interior sound levels are low and the Comfort Series seat has an air suspension and is adjustable to fit the operator. A trainer seat promotes proper operational and safety training. Wide platform access stairs and optional window-washing platform also enhance movement around the outside of the cab.

The blade control is a low-effort, pilot-hydraulic joystick with controls that lift/lower, tip and tilt. An integrated switch allows single or dual-tilt operation; the control is floor mounted and is adjustable fore and aft; an adjustable armrest enables operators to find a comfortable position; and to aid high intensity discharge lights are an option as is a rear vision camera.

To speed maintenance work, Cat Product Link is available from the factory which allows the owner or the dealer to remotely monitor machine health, service needs and location. Another option is a service center that centralizes the location for filling fluid reservoirs.
