Guide pulleys
The minimum diameter of the guide pulleys must be 12 times the diameter of the rope.
Example:
Rope thickness ∅ 7 mm
Guide pulley ∅ 84 mm

OPERATION

CAUTION!
Danger due to brake being released!
Jolting can cause the load pressure brake to be released.
Do not use the winch for securing loads!
Danger to life and limb! Never stand under suspended loads!
Risk of accident! Lowering loads over prolonged periods may cause the braking system to become
hot. Observe cooling breaks!
Depending on the load, the maximum lowering duration is 2 - 5 minutes.
Check the braking function of the winch; there must be an audible clicking sound when it is turned
in the "LIFT" direction!
Check whether the crank handle has locked into position.
Check the rope/strap for damage and exchange if necessary.
Do not route the rope/strap over sharp edges.
To wind the rope/strap in without load, hold it slightly taut. In order for the brake to function correctly,
a minimum load of 25 kg is required.
When the rope/strap is under load, only wind it in so far that at least 1.5 x the rope diameter still
hangs off the pulley (Fig. 8).
Deflection angle
ADVICE
The deflection angle when winding the rope in or out must not exceed 4° (Fig. 6-1).
Winch operation
Lifting/pulling a load
1. Turn the crank handle clockwise.
Holding a load
1. Release the crank handle.
The load is held in its current position.
Lowering a load
1. Turn the crank handle anticlockwise.
The built-in brake stops the crank handle from flying back.
Automatic rolling mechanism
ADVICE
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.
