Mining equipment manufacturer Caterpillar has introduced new 834K wheel dozer, which is built on the strengths of its predecessors.

With new cab, drive train refinement, monitoring and diagnostics, safety features and structural enhancements, Caterpillar says the 834K Wheel Dozer is production-focused power train.

The 496 horsepower (370kW) C18 engine in the Cat 834K wheel dozer is available in three configurations tailored for any region of the world.

Available configurations include the Tier Four Final (Stage IV) with a diesel particulate filter and a selective catalytic reduction system to control emissions; Tier Three equivalent without after-treatment; and Tier Two equivalent without after-treatment.

The C18 uses the company’s mechanically actuated, electronic unit-injection system for precise control of fuel delivery, yielding optimum performance and economy in all operating situations.

To save fuel, 834K encompasses engine idle shutdown and engine idle kick-down systems and the delayed engine shutdown system protects the engine from hot shut-downs.

An on-demand, hydraulically-driven cooling fan reduces horsepower draw for increased efficiency.

The 834K axles feature shaft-mounted, oil-cooled, multiple-disc brakes.

To enhance production, the impeller clutch torque converter (ICTC) in 834K allows the operator to adjust rimpull from 100% to 25% in order to match hydraulic effort and rimpull to the operating situation.

834K also features a standard rearview camera, repositioned access ladders, full-perimeter railings and convenient ground-level panel that houses a stairway light switch, engine shutdown switch and lockouts for the starter and transmission.
