Crane track laying technical processes

Crane track laying technical processes

With the construction crane machine and parts promulgation and implementation of the new standard, universal  overhead gantry crane  for construction safety, environmental protection and energy reliability have become increasingly demanding, will bring the whole industry change the profit model, and continuously improve the core competitiveness and brand value.
      Universal  hoist gantry crane
 at what needs to be done before laying prepare it
    1, before laying rail rail end response, straightness and twist checks after passing laying.
    2, lifting the track rail mounting should be determined before baseline, the baseline should rail mounting location for the crane beam axis.
3, the actual track centerline on the centerline of the actual crane beam position deviation not greater than 10mm, and not greater than half the thickness of the cable car.
    4, the track center line of the installation of the actual level of the baseline position deviation, for general o overhead bridge crane , gantry cranes and handling general should not exceed 5mm  for bridge girder suspension cranes should not exceed 3mm.
    5, Universal gantry crane rail span tolerances shall comply with the following requirements.
