Product component composition and working principle


Component composition:

Tracks or tires: Excavator walking devices usually use tracks or tires, which are responsible for contact with the ground to provide walking support and traction.
Walking motor: The walking motor is the core component of the walking device, which provides power through the hydraulic system and drives the track or tire movement to make the excavator go forward, backward or turn.
Transmission system: The transmission system transfers the power provided by the hydraulic motor to the tracks or tires to realize the walking and steering operation of the excavator.
Retarders: Retarders reduce the speed of the transmission system and increase the torque output of the motor, thus providing greater traction and driving force.
Suspension system (crawler) : Crawler excavators are usually equipped with suspension system, which is composed of springs, shock absorbers, etc., to reduce vibration and shock, improve the comfort and stability of driving.
How it works:

Hydraulic drive: The walking motor of the walking device provides power through the hydraulic system. When the operator operates a lever in the cab, the hydraulic system supplies pressure oil to the walking motor, which drives the motor to rotate, thereby generating rotational power.
Power transmission: The rotating force generated by the walking motor is transmitted to the reducer in the transmission system, the reducer converts the rotating force into the walking force, and transmits the power to the track or tire through the chain, gear, etc.
Track or tire movement: The transmission system transmits power to the track or tire, causing it to create a rotating motion that propels the excavator forward, backward, or steering.
Steering operation: By controlling the steering lever in the cab, the operator can control the working direction of the hydraulic walking motor to achieve the steering operation of the excavator.
