The principle of the excavator telescopic chassis is as follows:

The principle of the excavator telescopic chassis is to use the hydraulic system to adjust the wheelbase and width of the vehicle to achieve better vehicle handling performance and Steering ability. The hydraulic system of the telescopic chassis consists of a hydraulic cylinder, a hydraulic pump, a control valve, hydraulic oil, etc. When the hydraulic cylinder is connected to the hydraulic pump, the hydraulic cylinder will pump hydraulic oil into the hydraulic oil tank, and the hydraulic oil will then be adjusted by the control valve to flow. Thereby realizing the telescopic deformation of the chassis.

Excavators, also known as excavating machinery, are developed on the basis of mechanical transmission excavators. They use a bucket to excavate materials higher or lower than the bearing surface and load them into transport vehicles or unload them. A kind of earth-moving machinery that operates periodically to the stockyard.
