ADJUSTING THE FRICTION CLUTCH
If the chain hoist does not lift the test load or if the
measured value deviates from the maximum load
capacity, the friction clutch must be readjusted.
SUSPENDED LOAD!
Never use the friction clutch as an
operating limit switch.
This would permanently damage the
friction clutch and the load could fall,
killing or injuring people.
PREPARING THE CHAIN HOIST
Sealing plugs
Remove the sealing plugs. A slight amount of
oil may thereby run out.
Hoist motor, gear unit and chain may not move
when adjusting the friction clutch. Block the
chain in the chain guide or use the slip force
test unit to block the chain.
ADJUSTING THE FRICTION CLUTCH
Set the friction clutch to 1.3 to 1.4 times the
maximum load capacity. Turning to the right
causes the friction clutch to engage at higher
loads, turning to the left causes it to engage at
lower loads.
Check the friction clutch; see “Checking the
friction clutch” page 35.
If the friction clutch can no longer be readjusted, it
must be exchanged. For this, contact ABUS Service.
See “ABUS Service” page 90.
