Girder Lifting Machine

Technical requirements for beam lifting machines:

1. The lifting mechanism and operating mechanism operate at low speeds to improve the positioning accuracy of the prefabricated beams and reduce the impact on the structure of the beam lifting machine.

2. The internal space of the beam lifting machine must be large enough to accommodate the lifting of prefabricated beams and the assembly of the bridge erecting machine.

3. The main steel structure should also be designed for disassembly and transport under the premise of meeting the strength, stiffness and stability.

4. When using two machines to lift prefabricated beams, the two machines must operate synchronously.
