Loading and unloading equipment and loading and unloading method

The invention relates to loading and unloading equipment and a loading and unloading method. The loading and unloading equipment comprises a rack (14), a supporting plate (4) and a mechanical arm, wherein the supporting plate (4) is used for bearing an object (5), the mechanical arm is connected with the rack (14) to form a four-bar mechanism (1), the supporting plate (4) is arranged on a rod piece, far away from the rack (14), in the four-bar mechanism (1), so that the supporting plate (4) is driven to reach the target position through swinging of the four-bar mechanism (1), the length of atleast one rod piece, used for forming the four-bar mechanism (1), of the mechanical arm is adjustable so as to adjust the inclination angle of the supporting plate (4) under different working conditions. According to the loading and unloading equipment, the use requirements under different working conditions can be better met, the operation of the loading and unloading equipment in the object circulation process is more r
