摘要

Caterpillar's model 834 wheel dozer has been an industry workhorse for almost 50 years. With the recent introduction of the 834K model, Cat has added significant improvements to the 105,000-lb (47,750-kg) unit that include a completely new cab, drive train refinement, new monitoring and diagnostic features, new safety features and structural enhancements. Available blade types include straight, universal, semi-universal and coal, ranging in capacity from 10.3 to 29 yd~3 (7.9 to 22.2 m~3). Rated at 496 net horsepower (370 kW), the Cat C18 engine used in the 834K is available in three configurations to tailor the machine for any region of the world: 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 shutdowns. An on-demand, hydraulically driven cooling fan reduces horsepower draw for increased efficiency.
