[0002] Electric hoists are increasingly used in various industries that require lifting due to their small size, simple structure, and accurate positioning. Electric hoists are generally driven by a sports car connected to them to run on the track. The sports car includes a plurality of rollers, which are driven by a power device to rotate on the track so that the sports car runs along the track. The rollers of existing sports cars generally include a driving wheel and a driven wheel, which are located on both sides of the sports car. The driving wheel is connected to the power device and driven directly by the power device, and the driven wheel is not driven by power, but is driven by the driving wheel when the sports car is running. However, when the track is not in good running condition, for example, there is a slope formed by debris or dust on the track, it is difficult for the driven wheel to cross these debris or slopes and continue to move forward, which will cause the electric hoist to be stuck on the track and unable to run.
