The minimum diameter of the deflection pulleys
must be 12 times that of the cable diameter.

OPERATION

CAUTION!
Danger of brake release!
The load pressure brake can release due
to vibration.
The cable winch should not be used to
secure loads!
Danger of fatal injury! Never stand under sus-
pended loads!
Risk of accidents! The brake system can over-
heat during extended lowering of loads. Ad-
here to the cooling periods.
Maximum lowering duration 2 - 5 minutes
depending on the load.
Check braking function of the cable winch.
There must be a clicking sound when turning
in the "lifting" direction!
Check the rope / strap for damage and re-
place if necessary.
The rope / strap should not be run over sharp
edges.
When winding up the rope / strap without a
load, keep it under a slight tension. For proper
braking function, a minimum load of 25 kg
is required.
Only wind up a cable/strap under load to the
point that there is an overhang on the flanged
wheels of at least 1.5x the cable diameter (6).

MAINTENANCE AND CARE

CAUTION!
Sharp edges!
Damage from scrapes, crushing, cuts.
Always wear work gloves.
CAUTION!
Risk of injury
At the end of maintenance and repair
work, reattach all covers with the original
screws!
CAUTION!
Danger from wear!
The winch operator must check the ca-
bles/straps for wear before every use
(DIN ISO 4309/BGR 500). Replace da-
maged cables/straps immediately.
The cable winch may only be inspected and
maintained by trained technicians.
The brake mechanism was treated by the ma-
nufacturer with a special grease (Wolfracoat
99113). Other oils or greases are not permis-
sible.
Inspecting the cable winch
The cable winch must always be inspected by a
trained technician:
