[0002] Stacker, also known as stacking crane, is a special crane that uses forks or skewers as a picking device to grab, transport and stack or pick and place unit goods from high-rise shelves in warehouses, workshops, etc. The main function of the stacker is to run back and forth in the aisles of the three-dimensional warehouse, store the goods at the entrance of the lane into the shelves, or take out the goods in the shelves and transport them to the entrance of the lane. The stacker consists of a frame (upper beam, lower beam and column), a horizontal walking mechanism, a lifting mechanism, a cargo platform, a fork and an electrical control system.

[0003] The horizontal travel mechanism of a common stacker is connected to a reduction motor to drive the moving wheels to move, thereby driving the stacker to move. However, in actual use, it is found that due to the high travel speed and weight of the stacker, when the reduction motor brakes, the moving wheels will drive the stacker to slide forward for a distance due to inertia, resulting in low positioning accuracy of the stacker. Utility Model Content
