The figures show the installation of a clamping buffer on the flange of an overhead travelling crane ELV. The installation on a lower flange on an overhead travelling crane ELK is very similar.

If the clamping buffers are not installed on the flange or the lower flange:

   Rotate the clamping buffer so that the rubber buffer points towards the trolley.

   Push the clamping buffer onto the flange or lower flange.

   Lay one side of the clamping buffer flat and tighten the fillister-head screw until hand-tight.

   With the horizontal fillister-head screw, pull the other side of the clamping buffer onto the flange or lower flange.

   Align the clamping buffer so that both clamping claws are lying flat on the flange or lower flange.

   Also ensure that the clamping buffer has a clearance of at least 5 mm to the profile end or to other components.

   Tighten the horizontal fillister-head screw. Tighten to 80 Nm.

   Tighten both vertical fillister-head screws. 120 Nm.

   Push the rubber buffer down until it lies against the flange or lower flange.
