A bridge magazine stacker
By setting a rigid connection between the column and the brake assembly in the bridge-type stacker crane and using frictional torque to counteract the inertial torque, the problem of increased gear contact stress caused by the inertial torque when the rotating motor stops is solved, thus improving the stability of the stacker crane.

AI Technical Summary
In bridge-type stacker cranes using bidirectional forks in limited spaces, the inertial torque of the load when the rotating motor stops increases the contact stress between the gear teeth, increasing the probability of gear breakage or plastic deformation and affecting the stability of the stacker crane.
By forming a rigid connection between the column and the brake assembly, the telescopic cylinder pushes the brake assembly to contact the ground to generate frictional torque, which counteracts the inertial torque and reduces the contact stress between the gears transmitted by the inertial torque.
This reduces the probability of gear breakage or plastic deformation, and improves the operational stability of the stacker crane.
