Basic structure of excavator

General structure of single bucket hydraulic excavator

The overall structure of single bucket hydraulic excavator includes power unit,

1. working device,

2. slewing mechanism,

3. control mechanism,

4. transmission system,

5. traveling mechanism,

6. auxiliary equipment, etc.

The excavator converts the chemical energy of diesel into mechanical energy through the diesel engine, and the mechanical energy is converted into hydraulic energy by the hydraulic plunger pump. The hydraulic energy is distributed to each actuating element (hydraulic cylinder, rotary motor+reducer, traveling motor+reducer) through the hydraulic system, and the hydraulic energy is converted into mechanical energy by each actuating element to realize the movement of the working device, the rotary motion of the rotary platform, and the walking motion of the whole machine.
