Cross beam type steel plate hoisting auxiliary tool

The cross beam type steel plate lifting auxiliary tool comprises a cross beam with an I-shaped section, a steel wire rope and a lifting hook, upper lifting plates are arranged on the cross beam at intervals, lifting holes are formed in the upper lifting plates, and the steel wire rope penetrates through the lifting holes to be connected with a main lifting hook; lower lifting plates are arranged at the two ends of the cross beam, penetrating holes are formed in the lower lifting plates, steel wire ropes penetrate through the penetrating holes, and two lifting hooks penetrate through the steel wire ropes and are oppositely arranged. The upper lifting plate and the lower lifting plate are arranged in the middle of the cross beam at intervals, and the lifting hook penetrates through the steel wire rope on the lower lifting plate, so that during lifting, the lifting hook is automatically clamped on a steel plate, the lifting hook is automatically tightened after the steel wire rope is stressed, the steel plate is
