AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

This reduces the probability of gear breakage or plastic deformation, and improves the operational stability of the stacker crane.
