The utility model discloses set up multiunit symmetry draw-in groove and lifting hook fixed slot on the davit, adopt bayonet lifting hook, through draw-in groove and the lifting hook fixed slot of putting into different symmetries, the adjustment hoisting point is to suitable distance, guarantees that the hoist cable is 90 with hanging the thing, avoids the hoist to appear sliding on hanging the thing, causes the incident.

The utility model discloses set up multiunit symmetry draw-in groove and lifting hook fixed slot on the davit, when hanging the thing overweight, can increase the bayonet lifting hook of multiunit and share and lift by crane weight to reduce the bearing of lifting hook, increase its life-span.

The clamping groove of the utility model is simple to manufacture, can be welded and manufactured by using on-site leftover materials, and achieves the effect of waste utilization; the operation is simple, the adjustment operation can be finished by a single person, the manpower is saved, and the production efficiency is improved.

The utility model discloses simple structure, the preparation of being convenient for can lift by crane the thing of hanging of different length, and the practicality is high, and safe high efficiency is good.
