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. No
continuous operation!
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 to ensure the crank is engaged.
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 rope / strap under load to the
point that there is an overhang on the flanged
wheels of at least 1.5x the rope diameter (sec-
tion 8).
Deflection angle
The deflection angle when winding the
rope in or out must not exceed 4° (
6-1
).
Cable winch operation
Raising, pulling the load
1. Turn the crank clockwise.
Holding the load
1. Release the crank.
The load is kept in the same position.
Lowering the load
1. Turn the crank anti-clockwise.
The integrated brake prevents the crank
from kicking back.
AUTOMATIC ROLLING MECHANISM
The automatic rolling mechanism can
only be actuated if the winch is without
a load.
Actuating the automatic rolling mechanism
1. Pull back the locking sleeve (
Fig. 1-2
).
2. Remove the crank handle.
3. Press the locking lever and turn it to the left
(
Fig. 2-1
).
The rope/strap can be unwound (Fig. 7).
