Unwinding the rope on its reel:
CORRECT
INCORRECT
Fixing the rope :
The ropes are supplied as standard with a rope attachment suitable for the recommended rope and installed
according to a standard rope outlet.
Align the rope clamp with the hole made in the winch for this purpose.
Pass the rope through the slot of the flange and place it between the flange and the rope clamp, taking care to
position it correctly in the rope clamp slot. Make the rope exceed the limit of the outer diameter of the flange.
Once the 4 screws are correctly tightened, the rope is properly installed.
The rope should not form loops in any case.
Winding the rope on the drum :
Tension the rope and wind it around the drum in close joining coils.
Check the winding direction of the rope according to the motor connection.
Start to wind the rope forming a spiral to the right. In order to facilitate this operation, some drums are provided
with a heel attached to one of the flanges, which "fills" the space between the first turn and the flange.
The first layer must be wound in a compact manner and under tension. Take a mallet or a block of wood and
knock the turns against one another; not too hard to prevent the strands from overlapping one another, but
tightly enough to prevent the rope from moving on the drum. If the first layer is wound too loose, the next layer
will form a space in the first layer that will result in an open area. If the first layer is too tight, the subsequent
layers will not have enough space between turns.
In any case, the first layer and all the other layers must be wound onto the drum with enough pre-tension (5-10
% of the MWL of the rope). If the rope is wound without any tension, it will suffer from crushing and premature
flattening caused by the loaded upper layers.
Even if the first layer is wound correctly during installation, it will expand a little while in service. When the first
layer expands (loss of pre-tension) the initial procedure MUST be performed at regular intervals.
Otherwise, the "hard" turns will severely crush the base layers.
Whatever you do, DO NOT pass the rope through a clamping mechanism. For example, two blocks of wood
screwed together.
THIS WILL CAUSE IRREPARABLE DAMAGE TO THE ROPE!
