Important Components And Daily Maintenance Of Backhoe Loaders
Summary: Backhoe loaders are used for filling and excavation of subgrade works, aggregate and loading of asphalt mixture and cement concrete yards. 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 easy operation, it has become one of the main types of earthwork construction in engineering construction.

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 : 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 of body (fixed axis).
The backhoe loader digs and loads and unloads materials through the movement of its working device. The loader should be compulsoryly maintained, inspected and adjusted, and pay attention to oil replacement. In short, the requirements for the use and maintenance of the loader during the running-in period can be summarized as: strengthen training, reduce load, pay attention to inspection, and strengthen lubrication. As long as we pay attention to and implement the maintenance and maintenance of the loader during the break-in period, it will reduce the occurrence of early failures, extend the service life, improve the operating efficiency, and bring more benefits.
