Overview
The SIMOGEAR electric-monorail gearboxes have a mechanical
clutch which safely engages and disengages power transmis-
sion by interrupting the force flow between the input and output.
Clutch for light-load applications
The position and operating travel of the clutch lever are de-
signed in accordance with VDI guideline 3643 on sizes BH.29
and BH.39.

Clutch on BH.29 and BH.39
Clutch for heavy-load applications
Position 1 is the standard clutch position on sizes KHF49 to
KHF79.
The end stop bolt (position 4) limits the operating travel from po-
sition 1 to 2, or from position 1 to 3. The operating travel can be
altered by changing the thread position. The position of the op-
erating travel is specified with the order.
Furthermore, a short version of the clutch is also available. The
relevant dimensions can be seen in the dimensional drawings
provided in the gearbox chapter.
