　The engine drives the hydraulic pump through the transmission and the power take-off device, and the high-pressure oil enters the lifting hydraulic cylinder through the distribution valve and the oil pipe, and the rod is pushed to make the carriage tip over. Lateral tilting is more common, and the vehicle board can be stopped at any required tilt position by manipulating the control lever. The car plate uses its own gravity and hydraulic control to reset. It greatly saves time and labor for container flatbed trucks operating in ports. There is a lot of space and value for promotion. Improve labor efficiency.
