As the saying goes, wood grabber is a wood grabber machine. The size arm of wood grabber is also known as the "grab arm", most of which are evolved from crawler excavator. Its key function is to carry out excavation and the loading, unloading and transporting of various strips of raw materials. The bottom net is woven to explain the components of the wood grabber:

1. Diesel engines.

2. Transmission has one (big planet type) and split (fixed shaft type) two kinds.

3. Working gear oil circuit, hydraulic oil filter element, working pump, multi-way valve, lift hydraulic cylinder and tip bucket hydraulic cylinder

4. Walk the fuel line: transmission engine oil pan oil, walk the pump, all the way into the torque converter into the gear valve, transmission clutch.

5. There are three pumps above the torque converter, working pump (supply lift, reverse bucket working pressure oil) steering pump (supply steering working pressure oil) speed regulating pump is also known as walking pump (supply torque converter, transmission working pressure oil), some models of steering pump is also equipped with the main pump (supply control valve main working pressure oil).

6. Steering fuel line: wood grab oil tank, steering pump, steady flow valve (or priority selection valve) steering gear, steering hydraulic cylinder.

7. Driver: rotating shaft, main transfer box, wheel reducer.
