AI Technical Summary
Traditional construction material lifts lack protective mechanisms, which can lead to lateral slippage of construction materials and insufficient adaptability to complex environments. In addition, the lack of fall protection mechanisms increases the risk to workers.
The design incorporates a protective mechanism and a fall arrest mechanism. The protective mechanism uses an electric telescopic rod to drive an adjustment plate and a folding door to form a lateral protective barrier. The fall arrest mechanism uses an electric push rod and a fixing clamp to achieve double fixation, ensuring that the material does not slip when falling.
It improves the safety and stability of the material lifting machine, prevents materials from slipping or tipping over, reduces the risk of human error, ensures that materials do not slip when falling, and reduces the probability of accidents.
