The new double girder bridge crane is a double beam product developed based on the lifting mechanism as a small electric hoist. It has advantages such as superior performance, safety and reliability, energy conservation and efficiency, and low noise and environmental protection. It is suitable for lifting and handling objects in workshops, warehouses, power stations, and other places. 

The machine adopts a lightweight, modular, and parameterized design. The lifting mechanism adopts a high-performance and technological advanced NRT small car electric hoist, The large car running mechanism is driven by a three in one drive device, and the control adopts an advanced frequency conversion speed control system. 

The crane frame adopts an H-shaped structure composed of one or two crossbeams and two longitudinal beams.The small tonnage crane crossbeams are placed in the middle of the beam spans at both ends, with one side rigidly connected to the end beam and the other side hinged to the end beam. The wheels of the small car can come into contact with the track under any working condition, reducing the accuracy requirements of the small frame.
