In construction engineering, the manual hoist is used to lift relatively heavy objects, and its load can reach 2T. But on the construction site, the simple manual hoist does not have a favorable support system, and the force-bearing support depends entirely on the site conditions, which is inconvenient to use.

In construction projects, there are more and more steel structure projects, but their installation is somewhat limited by geographical or other conditions. Many large-scale hoisting equipment cannot reach the site for construction. After the floor structure is completed, the working face of the tower crane cannot go to the basement, so that the steel beam installation of the basement cannot be hoisted normally by the tower crane, and it can only be completed by manpower and manual hoist construction. In the installation of the primary and secondary beams of the steel structure, the main beam can be installed by hanging the manual hoist on the column with the lifting lug installed in advance, and if the secondary beam is installed using the same lifting method as the main beam, the lifting lug must be welded on the main beam. on the beam, and then hoisted. However, the number of secondary beams is large, and some secondary beams are far away from the columns, and the beam plate of the main beam is relatively thin. Welding and cutting lifting lugs will cause damage to the main beam, and the construction efficiency is low.
