As shown in fig. 1 to 3, a transfer hanger for concrete precast slabs is applied to a transfer hanger for a concrete precast slab production line in the prefabricated building industry. The hanging bracket comprises a hanging bracket 1, wherein the hanging bracket 1 is a rectangular frame formed by welding H-shaped steel, two hanging plates 12 are symmetrically welded below H-shaped steel frames on two sides, a group of circular hanging holes 11 are transversely and uniformly distributed on each hanging plate 12, and the orifices of the hanging holes 11 are provided with round chamfers to prevent hanging pieces from being damaged. The four lifting holes 11 which are symmetrical to the center line of the hanger 1 are respectively provided with U-shaped shackles 21 for lifting, and the U-shaped shackles 21 are in the prior art and are detachably matched through thread formation. Each U-shaped shackle 21 is connected with a first lifting rope 2 with two circular-ring-shaped ends, and the first lifting rope 2 can be a steel wire rope or a chain. When the steel wire rope is adopted, the circular end can be manufactured in a pressing and inserting weaving mode, or the steel wire rope at the end is bent into a circular shape and is connected and fixed through the steel wire rope lock catch to form a closed ring. The other end of the first lifting rope 2 is connected with a bracket body 3 with a telescopic function. Four corner points above the hanger 1 are respectively welded with a hoisting plate 13 with holes, and each hoisting plate 13 is connected with the hoisting ring 5 through a second hoisting rope 4. Every second lifting rope 4 length is the same, and the slant sets up, guarantees the stability of whole hoist. The second lifting rope 4 may have the same structure and connection method as the first lifting rope 2, and will not be described again here.

Bracket body 3 includes a support frame 31, and support frame 31 forms for the shaped steel welding, and its both sides are H shaped steel boundary beam 31a of mutual parallel arrangement, three tie-beams 31b of equipartition welding between two boundary beams 31a, and tie-beam 31b adopts one or several kinds of specifications such as I-steel, H shaped steel, rectangular pipe, and boundary beam 31a and tie-beam 31b junction still are equipped with strengthening rib 31c, and whole support frame 31 upside is used for placing the concrete precast slab that needs the transportation for the plane. A fixing sleeve 32 is welded to each end of each edge beam 31 a. Specifically, as shown in fig. 2 and 3, the front end of the fixing sleeve 32 is flush with the end of the edge beam 31a, one side wall of the fixing sleeve is attached to the web of the section steel of the edge beam 31a H, and the upper and lower surfaces of the fixing sleeve are welded to the upper and lower flange plates on the inner side of the section steel of the edge beam 31a H. The fixing sleeve 32 is a rectangular tube with a length of 300-500mm, so that the stress area of the associated fitting part can be effectively ensured. Each fixing sleeve 32 is in sliding fit with a solid plate-shaped transverse suspension arm 33, and the cross section of each transverse suspension arm 33 is matched with the cross section of each fixing sleeve 32 in shape and is rectangular. The front end of the transverse suspension arm 33 is connected with a lifting lug 33b, and the lifting lug 33b is connected with the first lifting rope 2. By adjusting the reach of the transverse boom 33, the first lifting rope 2 is guaranteed to be vertical.
