As an indispensable equipment in construction, the safety and convenience of the lifting platform have received more and more attention. The traditional lifting platform requires manual operation, which is not only time-consuming and labor-intensive, but also has certain safety hazards. In order to solve this problem, the automatic lifting platform came into being.

[0004] Traditional lifting platforms are mostly manually operated and require manual control of lifting and lowering. The operation is complicated and inefficient. At the same time, due to the lack of safety protection measures, safety accidents such as falling from heights are prone to occur. In contrast, the automatic lifting platform has the advantages of high degree of automation, strong safety performance and wide adaptability. Through the control system, the lifting platform can achieve automatic lifting, reduce the tediousness and errors of manual operation, and improve construction efficiency. The lifting platform is equipped with a variety of safety protection devices, such as anti-fall devices, overload protection, etc., which effectively protect the lives of construction workers.

Therefore, it is an urgent problem for technical personnel in this field to develop an automatic lifting platform with simple structure, convenient operation and low cost under the premise of ensuring the automatic operation of the lifting platform and improving production efficiency and accuracy.
