Further, coupling mechanism includes bedplate, peg and jaw, the bedplate passes through the gusset to be fixed on the inside wall of through-hole, be provided with the peg between the bedplate, it has the jaw to articulate on the peg, jaw lower part fixedly connected with lifting hook group.

Furthermore, the upper part of the seat board is provided with a U-shaped groove with an upward opening, and the hanging shaft is arranged in the U-shaped groove.

Further, shaft end grooves with upward openings are formed in the two end portions of the hanging shaft, clamping plates are fixed on the rib plates through bolts, and the lower ends of the clamping plates are arranged in the shaft end grooves.

The utility model has the advantages that:

1. the utility model designs the hanging beam into an upper arch shape, so that the middle part of the hanging beam is arched upwards, and the design height of the hook group is lifted upwards while the strength of the hanging beam is improved;

2. the utility model arranges the connecting component of the hook group inside the hanging beam, which is supported by the hanging beam, and simultaneously reduces the upper and lower height of the connecting component, and lifts the design height of the hook group upwards again;

3. the utility model discloses with the design height of lifting hook group to lifting, make the lifting hook upper limit reduce, under the same condition of lifting by crane height, reduced the height of hoist, the weight of hoist reduces thereupon, has reduced the construction height of factory building, has reduced the manufacturing cost of hoist and the construction cost of factory building.
