The invention relates to a stacker lifting device, and relates to the technical field of stackers, the stacker lifting device comprises a bearing mechanism, a cargo carrying table, a hoisting mechanism, a pallet fork telescoping mechanism and a control system, the control system comprises a position detection structure used for detecting the position of the cargo carrying table and a control structure used for controlling the hoisting mechanism to start and stop; the detection structure comprises a rotary encoder and a linear encoder. The control system detects the rotation angle of the driving wheel or the idle wheel through the rotary encoder and calculates the theoretical position of the cargo carrying table. The linear encoder is installed on the bearing mechanism, the control system calculates the position and the moving distance of the cargo carrying table through the rotation angle output by the rotary encoder, and the actual position of the position of the cargo carrying table is detected through the linear encoder. And the relation between the angle of the rotary encoder and the position of the cargo carrying table is corrected by comparing the difference between the theoretical position and the actual position. The device has the effect of maintaining high operation precision after being used for a long time.
