SD6G Bulldozer
Features
SD6G bulldozer is 160 horsepower track-type dozer with hydraulic direct drive, semi-rigid suspended and hydraulic controls. It is equipped with Shangchai C6121 diesel engine manufactured under Caterpillar license. The engine has the characteristics of big torque reserve coefficient and capacity against over-load. The torque converter is a hydro-mechanical converter whose power is divided outside, which has the characteristics of wide high efficiency range. Steering and braking can be controlled with the same control lever. Braking system utilizes hydraulic boosting structure, which is convenient and labor-saving. The final drive gear has the characteristics of large displacement coefficient value. This kind of design raises bearing capacity and prolongs the useful time. The final drive also utilizes the structure that its bearing clearance is free of adjustment, which is convenient for service. The equalizer bar utilizes free lubricating structure to decrease service cost.
