Abstract

A hoisting assembly for use with a wire rope. A rope guide is configured to mount around a rotating drum having a spiral rope groove defined therein. The spiral rope groove on the rotating drum is configured to receive the hoisting rope as it winds and unwinds from the rotating drum. The rope guide is configured to move laterally relative to the rotating drum to keep the hoisting rope in the spiral rope groove when winding the hoisting rope onto the rope groove or unwinding it from the rope groove. A sheave set may be configured to move along the longitudinal axis of the rotating drum while the hoist rope is unwinding from the rotating drum. The sheave set tensions and guides the hoisting rope and works in connection with a swivel sheave to accommodate the rope angle with respect to the axis of the rotating drum. Accordingly, the assembly is configured for spooling and unspooling the hoist rope to move the load in a completely vertical direction.
