AI Technical Summary
The twin-screw synchronous drive structure of stacker cranes is prone to problems such as deviation in drive speed on both sides and slight tilting of the loading platform during long-term operation, which affects positioning accuracy and equipment life and poses safety hazards.
A laser rangefinder is used to monitor the distance between the two sides of the loading platform in real time. The controller adjusts the speed of the synchronous motor to keep the loading platform level, reduce wear on the drive components, and trigger an alarm when a problem occurs.
It improves the stability and positioning accuracy of the loading platform, reduces wear on transmission components, lowers the risk of equipment failure, and enhances the operational reliability of the stacker crane.
