AI Technical Summary
In the prior art, the gantry crane only has a stopper at the end of the track without a buffer, which causes the stopper to be easily damaged by the gantry crane, thereby increasing construction costs.
A stop column and a speed reducer are set at the end of the track. The distance from the speed reducer to the mounting base is smaller than the distance from the side wheel to the mounting base. The gantry crane is slowed down by blocking the movement of the side wheels. The distance from the speed reducer to the stop column is larger than the distance from the side wheel to the collision surface. The side wheel first passes through the speed reducer and then moves toward the stop column, thereby reducing the impact speed of the gantry crane and reducing damage to the stop column.
It effectively reduces the impact of the gantry crane on the stop column, reduces damage to the stop column, reduces construction costs, prevents the gantry crane from rebounding back to the working area, and improves the stability and safety of the equipment.
