Abstract
An endless cable winch includes a working cable, a housing, in which is mounted a driving cable pulley around at least a part of which the working cable is wrapped, and further includes a drive for driving the driving cable pulley, wherein the housing is mounted so as to be pivotable about a pivot axis, and a sensor is provided for detecting a pivoting movement of the housing for detecting an overload state of the working cable.
Claims20
An endless cable winch, comprising:
- a housing having a first end and a second end, said housing being mounted pivotably about a pivot axis at said first end and being suspended from an elongation element at said second end;
- a driving cable pulley mounted within said housing;
- a working cable being wrapped at least partially around said driving cable pulley;
- a drive for driving said driving cable pulley;
- an overload detection device for detecting an overload of said working cable, said overload detection device comprising a sensor for detecting when a pivoting movement of said housing exceeds a certain pivot angle, thereby indicating an overload of said working cable.
