Winch with helix gear and puling force of 2x11,5t. Hydrostatic drive of the winch enables that we can get maximum power from the winch and it protects the chains and steel rope from damaging. At the beginig the winch is pulling slowly but after a predetermined time the speed increases at the avarage speed of 0,8 km/hFeatures of unwinding device:
- helps the user to unwind the steel rope
- it ensures the tightnes between pulley and drum, which help to get more precise widing of the rope to the drum. This consequetly prolong the lifetime of the steel rope.
- Unwinding device ensures higher safety, reliable operation and usage.
Unwinding device is assebled from purpuse-built upper pulley with hydromotor, electro-hydraulic control unit, electrical equipment and corresponding hydraulich hoses. In the pulley, there is assembled the rode with springs for setting the pressure betwen thick and thinner rope.
When we start the unwinding function, the brake is released. Then the oil flow goes to the hydromotor of unwinding device. The rope goes of the drum until we stop the unwinding function. We can set the speed of winding on the winch hydraulic valve block. During winding the rope to the drum, unwinding device slows the rope so we can achieve the precise winding and longer lifetime of the rope.
