4-5 tons swing arm garbage truck from Chengli factory

Swing arm garbage trucks are mainly composed of booms, boom cylinders, feet, support cylinders, hydraulic systems, various high-pressure fuel pipes, and more air exchange valves and special balancing valves.
The oil cylinders are all equipped with supporting products of Dongfeng chassis. The outer diameter of the oil cylinder is 160mm, the inner diameter is 125mm, the stroke is 1680mm, and the cylinder rod diameter is 70mm. This vehicle is also equipped with a hydraulic balance valve device not available from other manufacturers to make the operation more stable. The car body material is made of high-quality materials from Wuhan Iron and Steel Company. The car body volume is 5 cubic meters, and the paint is the same as the cab (Dongfeng Blue). This car is equipped with a garbage hopper, which is not sealed. Special box for swing arm garbage truck (ground type), box body material: made of high-quality carbon steel plate of Wuhan Iron and Steel Co., box body thickness: three sides and four bottoms (mm), paint is consistent with cab color.

working principle:
The power take-off obtains power from the transmission, drives the hydraulic oil pump to rotate, and generates high-pressure oil to be sent to each cylinder. The cylinder rotates the boom around the twisted point to lift and unload the hopper. When dumping the garbage, first open the car cover, the hopper uses the axis as the fulcrum, and the lifting arm rotates around the hinge point, so that the hopper tilts backward to complete the purpose of unloading.
Before lifting, the support legs must be lowered to ensure the stability and safety of the vehicle. Before driving, the outriggers must be retracted to the highest position. When the long-distance transfer should also pay attention to whether the outriggers automatically loosen.
