Gantry crane selection

   Crane installation works just as important to their design and manufacture. Crane installation merits of the quality of the installation work ability, crane structural parts and component life,  hoist gantry crane  design performance, production and use, and security has a great economic impact.
    Lifting equipment installation engineering starting from the device out of the box, to the equipment installed, and through commissioning, commissioning qualified, handling project acceptance so far. Because cranes are of special equipment, with higher risk characteristics, therefore, the installation of the crane, the security is especially important to pay particular attention to the following aspects:
    1, cranes are mostly large structure, institutional complex mechanical devices, it is often difficult overall transport is often split after shipping the equipment to use the site as a whole assembly. Therefore, it is necessary in order to reflect properly installed  overhead gantry crane  overall eligibility to test the integrity of the whole crane and integrity.
    2, the crane is in use party sites or buildings orbit. Therefore, its orbit or install base, and the crane itself, is able to complement each other well, and the ability to run whether they can adapt to meet strict requirements, must go through the proper installation and post-installation commissioning and testing concluded .
    3, crane high security requirements, safety devices must be complete and properly installed, in order to achieve a reliable, flexible, and accurate technical requirements.
    4, according to the importance of safe working crane, the crane was put into use in order to meet the operational requirements of various loads, it must be conducted according to the provisions of the crane load, full load, overload tests. These tests must be the operating state of the crane mechanism or specific for a stationary state. This requires the bridge gantry crane  load test after installation only after the transfer of use.
    5, cranes, wire rope and other flexible member, and many other parts will occur in some of the initial elongation under load, deformation, loosening. It also requires the crane installation, commissioning loaded after correction for repair, adjustment, handling and fastening. Therefore, we must do a good job crane installation, commissioning, adjustment and some out work in order to ensure the future safety of the crane normally used.
