The device uses a single-groove pulley and a steel wire rope instead of a large hand-operated hoist as a main bearing point, and connects a small-specification hand-operated hoist from a vice lifting lug position to solve the technical problem of difficult horizontal degree adjustment caused by the large specification of the hand-operated hoist.

[0006] The utility model adopts the following scheme to solve the technical problem:

[0007] The balanced beam hoist comprises a crossbeam, which is a main bearing structure for providing installation and support; an upper baffle, which is fixedly arranged on the upper part of the two sides of the crossbeam and has a trapezoidal structure; a lower baffle, which is fixedly arranged on the lower part of the two sides of the crossbeam and has a double-layer structure; a main lifting lug, which is fixedly arranged on the upper part of the two sides of the crossbeam and has a lifting point for connecting a traveling crane; a vice lifting lug, which is arranged on the protruding part of the upper baffle and used for connecting a small-specification hand-operated hoist and a sling for horizontal degree adjustment; an unloading buckle, which is assembled in the lifting point of the main lifting lug; a single-groove pulley, which is assembled between the two layers of the lower baffle; and a steel wire rope, which is assembled on the single-groove pulley and extends downward at both ends.

[0008] The branch pier is arranged at the bottom of the crossbeam and movably assembled with the side wall of the crossbeam.

[0009] The main lifting lug and the inner side of the upper baffle are arranged to mutually strengthen the tensile strength.
