Rope direction
Almost all rope directions are free selectable at installation of rope when the rope drum is ungrooved.
When the rope drum is grooved, the rope direction is specified by the by the rope grooves and also by a
possible existent overload protection. At works it will be delivered the rope direction “A”.
Will there be changes at the rope direction pay also attention of an adequate change of control.
Rope direction A

Replace the plug screw by a ventilation screw (attached) before putting the unit into operation. Otherwise
the ventilation screws are already installed.
Limit switch
▫ Serial winch is a lifting winch.
▫ Pulling winch as option.
Function: Operational and emergency limit switch.
It is possible to connect an external electric limit switch.
Overload protection by current cut-off
▫ Serially fitted with electronic overload protection for units of 1000 kg and up.
▫ Electronic overload protection for units up to 1000 kg available as option.
The overload protection is adjusted by the manufacturer according to the regulations that apply. The
overload protection prevents lifting a load that is too heavy by switching off the hoisting motor. When putting
the winch into operation or after current of the winch has been cut off or after the overload protection has
operated, press the button "lowering" shortly to re-activate the relay. A re-adjustment i.e. for maintenance
reasons is possible.
