[0002] At present, when dump trucks are in use, tires are prone to damage, so a spare tire needs to be placed on the vehicle for emergency use. The spare tire refers to the spare tire of the car, and its specifications are the same as the original car tire specifications. However, in order to remind the owner to check and replace the faulty tire in time, some cars will use spare tires in the form of special color rims, small spare tires, folding spare tires, zero-pressure tires, etc.

[0003] The spare tire is usually placed in different positions of the car according to the situation of the car and the needs of the user, so that if the tire of the dump truck is damaged, the spare tire can be replaced in time.

[0004] For example, the traditional dump truck spare tire lifting mechanism mainly adopts a winch-type (hand winch) lifting mechanism. The winch-type lifting mechanism needs to be fixed on the crossbeam column on the front plate. Both lifting and lowering need to be pulled and dragged by manpower. Single-person unloading and installation are time-consuming and laborious. For this reason, we propose a dump truck spare tire lifting system. Utility Model Content
