[0002] As one of the main forms of modern industrial buildings, steel beam buildings are increasingly widely used. During the later construction process of steel beam buildings, it is necessary to install mechanical and electrical pipelines. A large number of mechanical and electrical pipelines need to be installed on steel beams, and the installation height is relatively high. When installing mechanical and electrical pipelines, workers usually need to use lifting equipment to lift the mechanical and electrical pipelines to the corresponding height before installation can be carried out.

[0003] The existing mechanical and electrical pipeline lifting equipment mainly has the following two structures: one is a truck crane, which is used to lift mechanical and electrical pipeline materials; the other is an aerial work platform, which is used to lift mechanical and electrical pipeline materials. The existing mechanical and electrical pipeline lifting equipment has the following deficiencies, such as:

[0004] 1) When using a truck crane for lifting, the cost of the truck crane is high, and the required construction and installation costs are high, increasing the lifting and installation costs;

[0005] 2) Truck crane equipment is usually relatively large and occupies a certain space, which is not conducive to the use of space;

[0006] 3) When using a truck crane for lifting, it is easy to have unstable lifting, which not only affects the progress of the lifting operation to a certain extent, but also increases the danger during the lifting operation;

[0007] 4) For larger or heavier materials, two aerial work platforms are required to lift them simultaneously, which requires the close cooperation of the operators of the two vehicles, increasing the difficulty and safety risks of lifting and having high requirements for the operators.
