[0007] The traction end of the pull rope is operated by the construction personnel to pull the component.

[0008] The beam strut consists of a steel pipe and end screws, with internal threads at both ends of the steel pipe that connect to the end screws.

[0009] The inter-beam strut is located between two adjacent steel beams, perpendicular to the lower flange of the steel beam. The end screws are adjusted to ensure close contact between the inter-beam strut and the steel beam. It plays a supporting role during hoisting and balances the horizontal force generated during hoisting.

[0010] The first connecting member includes a first short column top plate, a first short column, a short column bottom plate, a U-shaped plate, a first connecting rod, and a first inverted U-shaped plate. The first short column top plate and the short column bottom plate are respectively fixed to the top and bottom of the first short column. The first short column top plate is fixed to the lower flange of the first side steel beam. The U-shaped plate, the first connecting rod, and the first inverted U-shaped plate are sequentially arranged at the lower end of the short column bottom plate. The first pulley is arranged inside the U-shaped plate, and the second pulley is arranged inside the first inverted U-shaped plate.

[0011] Stiffening ribs are provided on the first short column.

[0012] The second connector includes a second short column top plate, a second short column, a connecting sleeve, a second connecting rod, and a second inverted U-shaped plate. The second short column top plate and the connecting sleeve are respectively fixed to the top and bottom of the second short column. The tie rod is fixed inside the connecting sleeve.
