Installation Considerations instructions crane beam

 Universal  hoist gantry crane
 girder is installed at the same time should pay attention to what
    1, the crane girder installation must be in Turin mouth secondary grouting concrete strength of 70% before and after lifting roof. In special cases, it may, after lifting the roof or the roof lifting simultaneously. According to the weight of a universal crane girder gantry crane lifting, such as lifting the roof has been completed, the available short boom crane or a one-man (or one word) mast.
    2, stacking crane beam spot position should be arranged in close proximity to the installation location, the crane beam centering Installation Center. General car frame installation order from the column end to the other end of the sequence advances, but also from the middle to both ends of the forward.
    3, crane girder general lashing lashing points. Universal  overhead gantry crane  beam with rings, the rings can be hooked directly lifting slings. Weight 5t crane beam above rings and rings available cards, hanging elements interconnected lifting; beam embedded rings is not set, and can be used at both ends of the portable crane hanging around the house with the card under the beam banding.
    4, the installation will be using a common crane girder  bridge gantry crane  slowly lifted to the design position 10cm away from the bearing surface see, the use of human righting, the bearing surface of the beam centerline and the centerline (or adjacent to the crane beam centerline Ann) aligned, and to hold both ends of equal length, and then slowly fall, if any deviation is pulling with a crowbar, such as going seat uneven, with oblique iron pad level, you can be decoupled. When the beam height and width ratio greater than 4:00, when the number before the application of decoupling the beam and stub wire tied together to prevent windy dumping.
