目前，自卸车的卸货方式主要有后倾式、侧倾式、三面倾式三种。后倾式自卸车卸货时的车厢重心高度与车厢长度成正比，为了保证整车的工作安全性，车厢长度不能太长，一般长度不大于６m。侧倾式和三面倾式自卸车卸货时车厢重心高度与车厢长度无关，仅与车厢高度成正比；但车厢过 At present, dumping unloading mainly dumping-style, roll-type, three-lean three. Back dump dump truck unloading center of gravity height and carriage length is proportional to the vehicle in order to ensure the safety of work, the length of the carriage can not be too long, the general length of not more than 6m. Crouching and tri-surface dump truck discharge center of gravity when the height of the carriage has nothing to do with the length of the carriage, but proportional to the height of the carriage;
