Before installation, weld the segmented transportation guard rails according to the guard rail diagram and check the dimensions. If there is any bending or twisting deformation, it must be corrected. Before welding, try to support or suspend the guard rail in place and adjust it, with the following requirements:

1) The inner distance and deviation of two parallel guard rails are 1mm.

2) The symmetry tolerance between two parallel guard rails and the centerline of the conveyor shall not exceed 2mm.

3) The distance from the roller track (distance between the upper guard rail and the upper rail, and distance between the lower guard rail and the lower rail) is 2mm.

After adjustment, connect the support rail connecting frame to the guard rail and steel rail. First, spot weld the guard rail connecting frame in the middle and at both ends, and then remove the support or suspension of the guard rail. Check the above dimensions, and after passing the inspection, draw a line to determine the position of each connecting frame. Finally, weld all connecting frames to the track and guard rail symmetrically and spaced one by one. At this point, all tracks have been installed, and the support between the brackets of the curved and inclined sections can be welded.
