450 ton Lifting beam gantry cranes can be used to lift two-piece prefabricated beams at the same time, and a single gantry crane equipped with double hoisting equipment to lift prefabricated beams separately. The lifting capacity of two lifting machines at the same time is generally 450 tons, and the lifting capacity of a single lifting machine. The weight is usually up to 900 tons.
This type gantry crane is equipped with leg walking, crane walking and crane lifting equipment, which can achieve all-round mechanized action. It is mainly used to lift the prefabricated beam from the beam-making platform to the beam storage platform.
After the prefabricated beam is completed, it is lifted from the beam-holding platform to the beam-carrying vehicle. As a lifting device, complete the assembly and disassembly of the bridge machine. It is also used to erect bridges with low
1.The lifting mechanism and running mechanism have low running speed, so as to improve the alignment accuracy of the precast beam and reduce the impact on the structure of the lifting beam.
2.The internal space of the lifting machine must be large enough to meet the requirements for assembling prefabricated beams and bridge erection machines.
3.The main steel structure under the premise of meeting the strength, rigidity and stability, consider disassembly and transportation.
4.When two prefabricated beams are used for lifting, the two machines must be operated synchronously.
Operation and maintenance
1.The operator must go through training before passing the job.
2.Strictly in accordance with operational requirements, operating procedures to operate.
3.Regular inspection and maintenance of mechanical devices and electrical devices.
4.Find any problems should stop checking until the problem is solved
