The buffer rods prevent two trolleys (e.g. from two cranes) 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.

On the mounts of all trolleys:
Distance for 284 mm length | |
|
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 mounting plate
against the hole pattern on the trolley side panel.
Screw on the mounting
plate with the rib screws M6x12. 19 Nm.

Mount |
Rib screws M6x12 |
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.

Buffer rod |
Rubber buffer |
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. 19 Nm.

Threaded bracket |
|
Screw the threaded bracket
loosely to the mount at first using the self-locking nut M8.
Slide the buffer rod into
the threaded bracket on both sides.
| |
Rubber buffer |
|
Align the buffer rods to
both trolleys. The rubber buffers must be exactly above one another.
Tighten the rib screws
M6x12 on the side panel. 19 Nm.
Screw the threaded bracket
tight. 25 Nm.
Note:
If a greater distance between two cranes is required than is possible with the buffer rods, an additional trolley with buffer rods on both sides can be mounted between the cranes.
