The crane rail is a crane running route laid by rails, which ensures that the crane runs along the prescribed route and transmits the wheel pressure to the foundation. Crane rail can be divided into light rail type (P) and heavy rail type (QU). Small tonnage, medium tonnage crane rail uses P-type railroad rail, large tonnage gantry crane rail uses QU type crane special rail or square rail.AQuHenan Dongqi Machinery Co., Ltd

  • Diagram a uses the straight seam welding, is not detachable structure. Crane track section stress can be included in the main girder stress, increase the bearing strength of girder, this crane rail connection mode is used for trolley track that working level under the M5.
  • Diagram b is the most commonly used fixed method in China. It is convenient to assemble, but it is difficult to disassemble.
  • C and d diagrams are applicable to the organization of M6, M7 and M8 at work level.
  • e and f diagrams are used for screw connection, for special cases where the bottom is not easy to bolt.
  • The g diagram is 3-6mm rubber at the bottom of the crane track, which can reduce the impact.
  • H diagram is a fixed method of circular rail.
  • I diagram is the way of the large car track fixed to the crane rail beam.

Crane Rail Safety Inspection

Check the rail, bolt, plywood before the crane rail installation, and replace it immediately if there are any cracks or irregularities. For the steel rail surface and side that are allowed to be repaired, the wear defect should not exceed 3mm steel rail, repair it before using.AQuHenan Dongqi Machinery Co., Ltd
