The invention discloses a lifting rack of a target loading and unloading trolley. The lifting rack comprises a pedal, a manual pump, a hydraulic cylinder, chain wheels, a lifting frame and a return valve control handle, wherein two chain wheels are fixedly mounted on two sides of the top end of the hydraulic cylinder and connected with the lifting frame through chains; the manual pump and an oil tank are arranged at the bottom end of the hydraulic cylinder, an oil discharge one-way valve is arranged between the manual pump and the hydraulic cylinder, a return valve and a pressure maintaining valve are arranged between the oil tank and the hydraulic cylinder, and an oil suction one-way valve is arranged between the manual pump and the oil tank; the pedal is arranged above the manual pump, and a compressed spring is arranged between the pedal and the manual pump; the return valve control handle is connected to the lower end of the hydraulic cylinder. The lifting rack can be used as a lifting device for the target loading and unloading trolley, so that a target is conveniently and rapidly replaced, the labor intensity of a worker is greatly reduced, and the production efficiency is improved. The lifting rack is mainly applied to replacement and maintenance of rotary targets of vertical coating equipment.
