5.4.3 Adjusting the wire extension force
The wire extension force must set accurately, so that the drum stops at once when pulling no longer
occurs. This will avoid dangerous drooping and sagging of the wire rope.
To adjust the wire extension form:
• release the fi xation nut
• release or tighten the screw acting on the brake band through the leaf spring
• tighten or release the screw to either increase or reduce the extension force
• tighten the fi xation nut again
5.5 Skidding
Set the hydraulic cylinder of the tractor three-point hitch in its lowest position. Firmly settle the winch
down on ground, engage the tractor manual brake and then start skidding your load. Press the black
push-button on the control panel to start spooling the rope on the drum. The rope must stop winding
up as you release pressure on the black push-button.
For safety reasons, windind of the rope is strictly possible by holding a consistent fi nger pressure on
the black push-button.
Do not raise the winch during skidding operations! (DANGER: you may damage your
driveline)
The nominal pull force is the maximum pull obtained with the fi rst rope windings on the drum. This is
the fi gure stated in the technical data and the manufacturer‘s identifi cation plate on the machine. The
pull force decreases as the rope winds up on the drum. The pulling speed is inversely proportional to
the pull force and reaches the peak speed as the rope is fully spooled onto the drum. With the rope
fully spooled on the drum, the pull force amounts 50-60% of the nominal fi gure.
