[0002] A monorail suspension crane is a lightweight lifting device that hangs workpieces from the crane. It is relatively simple and widely used. However, existing electric single-girder cranes are overly complex and expensive to operate. Therefore, simplifying the basic structure, reducing assembly and application complexity, and optimizing the structural design are crucial. Based on this, the inventors conducted research and proposed this proposal. Utility Model Content

The top and bottom ends of the beam side plates are welded to the beam top plate and the beam bottom plate respectively, and the side ends of the beam top plate are welded with reinforcement plates. The side frames are locked and installed on the outer ends of the reinforcement plates. The transmission box is mounted on the beam side plates. The output end of the lifting motor is connected to the transmission box for transmission. Wheel openings are prefabricated on the lower right and lower left of the beam side plates, and the lifting sheave is installed on the wheel openings through an angle frame.

[0006] The single-girder crane in this utility model is primarily used for fixed-point suspension lifting, and is equipped with two lifting reels for efficient and coordinated lifting operations. The overall structure is streamlined, and without redundant electrical equipment consuming energy, it is more energy-efficient and environmentally friendly. It is particularly suitable for lifting light equipment in small processing plants, and its combined use is effective.

[0007] A preferred technical solution: The lifting reel includes a side wheel and a center wheel. The radius of the side wheel is larger than the outer side of the center wheel, and the side wheels are symmetrically assembled on both sides of the center wheel.

[0008] A better technical solution: a plurality of reinforcing ribs are provided on the side plates of the beam.

[0009] A preferred technical solution: The transmission box includes an output gear and a transmission gear. The output gear is connected to the output end of the lifting motor. The transmission gear is installed at the side end of the lifting motor. The transmission gear rotates synchronously with the lifting reel through the shaft, and the output gear is meshed with the transmission gear.

[0010] A better technical solution: a reinforcing steel plate is superimposed on the beam top plate, and the reinforcing steel plate is locked and connected to the beam top plate.

[0011] A better technical solution: two lifting reels are provided, one at each end of the beam side plate.

[0012] The beneficial effects of the utility model are as follows:

[0013] The crane of the utility model is prefabricated with a wheel opening on the beam side plate, which is installed in the lower right corner or the lower left corner through an angle frame combination, and the installation method is simple; a side frame is provided at the outer end of the lifting drum, which effectively prevents the wire rope wound on the lifting drum from deviating outward, plays a safety protection role and enhances safety.
