At the same time, the number of pipelines, equipment, and cables required for HVAC, water supply and drainage, power, process, and electrical are increasing significantly. In electromechanical installation, electromechanical pipeline installation is an important one. In the construction of large-scale factories, it is often necessary to install a large number of heavy pipelines on the inside of the roof of the factory. At present, self-propelled elevators are usually used for auxiliary installation. First, lifting equipment is needed to place the pipeline from the ground to the top of the elevator guardrail;

The operating angle is limited, and the workers are prone to fatigue, resulting in uneven installation quality of mechanical and electrical engineering, affecting the installation accuracy and speed. At the same time, when installing the air duct, since the installation position is generally high, the existing lifting device has poor stability when supporting the pipe, and the pipe is prone to shaking, which is unsafe during the lifting process.
