WJK rail clips installation method
There are seven parts for each set of WJK rail clips,
(1) The base plate is welded with the upper flange plate of the steel crane girder by three-sided surrounding welding or two-sided side welding, which can ensure the smooth transmission of the horizontal force of the crane to the crane girder. Moreover, the defect of weakening the flange section caused by a large number of openings in the flange of the crane beam is avoided. Therefore, the section bearing capacity of the crane beam is effectively improved.
(2) The WJK base plate and the lower end of the T-bolt form a spherical hinge connection. Therefore, the T-bolt is kept perpendicular to the upper cover under the lateral force, and yaw is allowed to occur. It can reduce the damage of the lateral impact force of the crane to the structures such as the track, the crane beam, and the braking system. Thereby extending the service life of the structure.
(3) WJK rail clips are equipped with a gauge adjustment plate for adjusting the gauge. It can improve the installation accuracy and reduce the deviation of the centerline of the rail. It has a two-way self-locking function to prevent loosening during use.
(4) The WJKT type bolts and the upper cover are free to disassemble and assemble, which provides extremely convenient conditions for construction, installation, and maintenance.
(5) The WJK upper cover plate is consistent with the curvature of the rail section, which can compress the rail without preventing the rail from sliding slightly in the longitudinal direction. It is also conducive to the full-length welding of the track.
(6) The arrangement spacing of the fixing parts can be determined according to the lifting weight of the crane, Q≤275t, the spacing is 600mm; that is, Q>275t, the spacing is 500mm.
(7) When welding the base of the fixed part and the crane beam, the selection of the electrode type should be compatible with the material of the connecting part. For example, when using Q235 and Q345 steel, use E4315 and E5015 electrodes respectively.
