Abstract
A clamping mechanism for releaseably securing the end of a rope to a winch drum. The winch drum includes first and second walls that are spaced apart in facing relation to each other to define therebetween a rope end receiving space having open front and rear ends. One of the walls in the space is contactable by the rope end that is to be secured to said winch drum. A clamping wedge member has an axis, a drum side contactable with the other of the winch drum walls, a rope side contactable with the rope end, and a drive end to which a first axial force can be applied. Application of the first axial force moves the wedge member axially into the space and causes a first lateral clamping force be applied, initially clamping the rope end against the one wall. A transverse thrust device is mounted on the drum for applying a transverse force against the drum side of the wedge member transversely of the wedge axis to cause a second lateral clamping force to be exerted against the rope end.
