Rotary crossing hanger

The utility model relates to a rotary crossing hanger which is used for the hoisting of large cylindrical objects and comprises an I-shaped main beam and an I-shaped accessory beam, wherein the main beam consists of a left part and a right part; an interval is arranged on the abutting end of the two parts, and the two parts are fixedly connected into a whole by an upper arc cover plate, a lower round cover plate and a vertical end plate; the accessory beam passes through a hollow frame in the middle of the main beam and the center of the accessory beam is connected with the main beam in a crossing and rotary manner by a central axis; a double lug plate is arranged on the upper surface of the upper cover plate; the free end of the double lug plate is fixedly connected with two ends of a hanger shaft; two sides of the main beam and the accessory beam are respectively provided with a movable lifting frame which is fixedly connected with a lifting arm in a downward manner; and the lower end of the lifting arm is vertically and fixedly connected with a bracket. The rotary crossing hanger utilizes drive mechanisms such as a motor, a screw rod gear wheel and the like to realize the rotation of the main beam and the accessory beam of the hanger and the distance adjustment between lifting arms, thereby reducing labor intensity for hoisting operation and improving working efficiency. Therotary crossing hanger has firm and reliable hoisting and can serve as a supporting leg to support the hanger without additional hanger bracket when not in use.
