The buffer rods prevent two trolleys (e.g. from two trolleys on one crane) from running into each other. They are made up of a metal frame on the side panels of the trolley and one rubber buffer each.

Two different lengths are possible for the buffer rod mounts on the two trolleys depending on the trolley and chain hoist combination.

   Read off the required trolley and chain hoist combination from the table.

At all four mounts:

   Depending on the previously determined length, prepare two mounts each for "distance left" and "distance right".

─     Saw the mounts off at a right angle in the appropriate position for 192 mm length.

─     Leave the mounts at their full length for 284 mm length.

   Deburr the sawed edge if necessary.

On both sides of the trolley and on both trolleys:

   Hold the mount against the hole pattern on the trolley side panel (or the mounting plate).

   Tighten the mount using rib screws M6x12 (2x each), only hand-tight at first.

   Shorten the buffer rod evenly on both sides in accordance with the flange width.

The rubber buffer must be exactly in the centre of the buffer rod later.

   Screw the rubber buffer to the buffer rod using the self-locking nut M8. Tighten to 19 Nm.

   First screw the threaded bracket loosely to the mount using the self-locking nut M8.

   Slide the buffer rod into the threaded bracket on both sides.

   Align the buffer rods to both trolleys. The rubber buffers must lie exactly over one another.

   Tighten the rib screws M6x12 (2x each) on the side panel. 19 Nm.

   Screw the threaded bracket tight. 25 Nm.
