Loading & Hauling  


Caterpillar has introduced the latest version of the Cat 834 wheel dozer, the 834K. The new model builds on the strengths of its predecessors with a completely new cab, drive train refinements, new monitoring and diagnostic features, new safety features and structural enhancements.

The 834K is available with straight, universal, semi-universal and coal blades, ranging in capacity from 7.9-22.2m³. Rated at 370kW, the Cat C18 engine is available in three configurations to suit different geographical markets: Tier 4 Final (Stage IV) using a diesel particulate filter and a selective catalytic reduction system to control emissions; Tier 3 equivalent without after-treatment; and Tier 2 equivalent without after-treatment. Fuel-saving enhancements for the 834K include 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 power draw for increased efficiency.

The Cat 4F/3R planetary power-shift transmission used in the 834K features a new Advanced Productivity Electronic Control Shifting system, which is designed to provide greater machine momentum through shift points, enhancing performance and saving fuel. The 834K axles feature shaft-mounted, oil-cooled, multiple-disc brakes, and the braking system can be equipped with auxiliary oil coolers for added protection.

The 843K also is equipped with the Cat next-generation Vital Information Management System (VIMS 3G), which features a large touch-screen interface and easy-to-use navigation to keep operators informed of machine operating parameters. The system, with data-logging capability, features an Ethernet connection module and an integrated Cat Product Link telematics system, which transmits data to a secure web-based application (VisionLink) for use by equipment managers.
