Single girder gantry crane gear installation steps

   With the national electric power, petrochemical, steel, transportation and other infrastructure construction reached a climax, the domestic single girder   overhead gantry crane   with rapid market expansion, the trend of large crane has become an irreversible fact. In order to reduce production costs, saving manpower and resources, the demand for large cranes has gradually expanded. The requirements for crane lifting capacity is growing, lifting speed is becoming more demanding, it is bound on the energy performance of the control and cranes have become increasingly demanding.

      As automated production process in the important part of the operational aspects of a simple, safe, reliable performance, easy maintenance are the basic requirements for  hoist gantry crane  s, in addition, the high cost of lifting machinery will be more in the future market.

    Today, as we introduce single girder gantry crane gear installation steps:

     1 with a feeler lateral backlash gear, shall comply with the relevant provisions of its minimum value, if measured with the pressure of lead, the lead wire along the outer edge of Busi gear tooth pitch length of not less than five, turning gear, the gear will be lead wire flattening, remove, respectively, with flattened lead wire micrometer thickness, the minimum value should be specified.

     2 with Hongdan coloring, Inspection Measurement single girder gantry crane gear contact case, is: Hongdan thin and evenly on both sides of the pinion tooth surface, turn the high speed shaft, the large gear pros direction of rotation, see contact marks, and calculate the percentage of contacts whose values ​​should be consistent with the relevant requirements.

     3 single girder   bridge gantry crane   installation and adjustment of open gear requirements above, but can reduce the contact point precision grade 1-2 level, according to the 8-9 level checks.
