Bolted Rail Fixing Clips

Bolted Rail Fixing Clips

Bolting is a very well understood method of making a fixing in engineering and the Gantrail bolted clips are the easiest to install.  They can be used with different grades of bolt and some clips can be fitted over studs welded to the steel rail support surface.

Gantrail recommend the use of grade 8.8 bolts for all normal applications as they offer the most economical solution.  Some construction site requires only grade 8.8 bolts are used.

Size for size welded clips give a stronger installation but bolted clips are often more convenient.

  1. Find or estimate the horizontal force to be carried by the clip. It is assumed that all of the load from one wheel will occur at one clip. If the load is not known it may be assumed to be 15% of the vertical wheel load.
  2. Choose the style of clip you require – bolted or welded. These are identified with their respective strengths in the table below.
  3. Find the dimensions of the foot of the rail to be used. See Crane Rails.
  4. Check that the selected clip will fit the installation. The table gives the dimension that must be added to the foot width of the rail to give the minimum support width.
  5. Check that the other clip dimensions will suit the application by referring to the Gantrail data sheet for the clip. These only show a limited number of rail sections and Gantrail can advise on other sections.
