AI Technical Summary

Technical Problem

In the process of handling goods, the mast angle of existing forklifts is difficult to determine accurately, which leads to the forks not being level, causing the goods to be squeezed and slipped, posing a safety hazard. In addition, improving the multi-way valve is costly and has a complex structure.

Method used

An angle sensor is used to detect the angle between the outer gantry and the horizontal plane. The rotation of the outer gantry is controlled by a mechanical multi-way valve assembly, and an alarm is issued when it is not vertical to prevent descent. The combination of a unique linkage structure and a Hall-type angle sensor improves detection accuracy and flexibility.

Benefits of technology

It achieves low-cost automatic fork leveling, improves safety and operational accuracy, reduces production and maintenance costs, and enhances versatility and flexibility.
