The invention relates to a trolley capable of lowering the labor intensity of the waist and a using method of the trolley. The trolley comprises a frame. A bearing table is connected to guide rails on the frame in a sliding manner, an air pump is fixedly arranged at the lower end of the frame and connected with power supply equipment on the frame, the air pump is connected with an air storage tank through a pipe, the air storage tank is connected with an air cylinder and air through a pipeline, one-way valves are arranged in the pipe and the pipeline, an air cylinder push rod is arranged at the lower part of the air cylinder, a stretching spring is arranged between the air cylinder push rod and the bottom of the frame; a first chain wheel, a second chain wheel, a third chain wheel and a fourth chain wheel are arranged between the bearing table and the air cylinder push rod, the second chain wheel and the third chain wheel are coaxially connected, a first chain is erected on the first chain wheel and the second chain wheel, a second chain is erected on the third chain wheel and the fourth chain wheel, the side, close to the bearing table, of the first chain is fixedly connected with the bearing table, and the side, close to the air cylinder push rod, of the second chain is fixedly connected with the air cylinder push rod. The trolley has the beneficial effects that the trolley can adapt to goods with different mass through the change in atmospheric pressure, the frequency of bending down in the handling process is reduced, and the labor intensity of the waist is lowered.
