AI Technical Summary

Technical Problem

Traditional construction material lifting methods suffer from high labor intensity, low efficiency, and poor safety. This is especially true in high-rise building construction, where manual handling is highly dangerous, simple cranes have poor stability, traditional hoist transmission systems are unreasonable, and the connection and separation of material carts are cumbersome, all of which affect construction progress and safety.

Method used

A high-efficiency material lifting device for construction was designed. It adopts a locking device and an improved gear chain transmission system. The material cart can be quickly connected and firmly fixed by moving the lever, which ensures the stability and safety during the lifting process. The inclined plate and chute structure simplifies the operation of the material cart and the lifting base, and improves the loading and unloading efficiency.

Benefits of technology

It enables rapid connection and separation between the material cart and the lifting base, improves material loading and unloading efficiency, ensures the safety and stability of material lifting, reduces the labor intensity and time consumption of construction personnel, and guarantees construction progress and safety.
