Additional lift-off protection
To increase the permissible lifting force for the mounting kits with constrainer, an
additional lift-off protection can be installed.
PR 6012/53S (M12) is provided for use in PR 6012/02 and PR 6012/32.
PR 6012/54S (M16) is provided for use in PR 6012/42.
For ordering information, see Chapter
.
Assembly:
-
Mount the threaded bar (1) so that it has sufficient free moving space in the drill hole.
-
Lock the nuts (2) so that there is a remaining distance A* from the washer (3).
* A = 2 mm
This distance is essential to avoid force shunts.
The required tightening torques are given in the following table.
