Threaded rods are required for all suspensions (except short suspensions) on which the crane track will later be suspended.

The threaded rods must be individually shortened or lengthened.

Shortening threaded rods:

  Shorten the threaded rod to the required length.

  Deburr the sawed edge.

  Mark a new hole for the spring cotter 6 mm away from the sawed edge.

If the HB crane runway is suspended parallel or at a right angle to the ceiling-mounted bracket: the new hole must be exactly aligned to the existing hole at the other end of the threaded rod.

If the HB crane runway is suspended in a different angle to the ceiling-mounted bracket: the new hole must lie exactly in the required angle at the other end of the threaded rod.

  Drill a hole (diameter 4 mm) in the threaded rod at the marked spot.

If necessary, e.g. to compensate for inaccuracies, the hole in the threaded rod can be drilled with a diameter of 5 mm.

Lengthening threaded rods:

  Screw the coupling (both sides with right-hand thread) on the threaded rods.

  Screw the second threaded rod in the coupling.

  Turn the coupling so that the borehole is visible.

  Insert spring cotters (2x).
