The pass-through, automatic, universal winch, is intended for pulling or pushing an object (P) such as sheet metals, flexible lines, ropes or chains. It is made of two non-parallel, angled discs (1) that by the peripheral parts of their inner walls form the line holder (2) that grips the object. The winch operation is based on the friction created in the line holder between the object (P) and the angled parts of the rotating discs (1). |
