Components Of A Backhole Loader
Backhoe loader includes engine, torque converter, gearbox, front and rear drive axles, referred to as four major parts 1. Engine 2. There are three pumps on the torque converter, working pump (supply lift, dumping pressure oil) steering pump (Supply steering pressure oil) Variable speed pump is also called walking pump (supply torque converter, gearbox pressure oil), some models are also equipped with a pilot pump (supply control valve pilot pressure oil) , Hydraulic oil tank, working pump, multi-way valve, lifting cylinder and tipping cylinder 4. Traveling oil circuit: gearbox oil sump oil, traveling pump, all the way into the torque converter all the way into the gear valve, transmission clutch 5. Drive : Drive shaft, main differential, wheel-side reducer 6. Steering oil circuit: fuel tank, steering pump, steady flow valve (or priority valve) steering gear, steering cylinder 7. Gearbox has integrated (planetary) and split Two types (fixed axis type).
Backhoe loader In road construction, especially in high-grade highway construction, the backhoe loader is used for filling and excavation of roadbed engineering, aggregate and loading of asphalt mixture and cement concrete yard. In addition, it can carry out operations such as soil transportation, leveling the ground and traction of other machinery. Because the backhoe loader has the advantages of fast operation speed, high efficiency, good maneuverability and light operation, it has become one of the main types of earthwork construction in engineering construction.
