Wire Rope Unwinding - Uniforest 45H Instructions For Use Manual

5. Wire rope unwinding

When the winch is properly connected, we can begin with unwinding of the wire rope.
On tractors without a socket with constant current of 12 V, we can connect a supply
cable in the socket, which is usually made for connection of light equipment on the trailer.
Because of this, we have to turn on the position lights.
On the steering console (figure 8), press the left button to release the brake. Hydraulic
cylinder shifts to position 1.
If we disengage pressure on the button in less than 3 seconds, the brake cylinder shuts
and the winch is again open and unwinding is not possible. If this button is pressed for
more than 3 seconds, the function shifts from "impulse" to "constant release" and despite
not holding the button, the cylinder stays in the open position and the winch in unwinding
function.
When unwinding, we have to be careful not to unwind the wire rope completely or leave
at least three winds on the drum. This distance is marked on the wire rope. Due to safety
reasons, the wire rope is installed on the drum so that if the logs start to slide without
control, the rope must "pull" itself off the drum. If the rope was pulled out with excessive
force, we can pull out the entire wire rope during pulling. In this case, replace it according
to the procedure, foreseen for wire rope installation. If the wire rope is very tight and we
wish to release it, we have to do it impulsively with quick presses 2-3 times on the left
button. This prevents the wire rope to unwind too quickly from the drum and that the wire
rope is not too loose. It also prevents the logs to slide downhill.
