A rope traction apparatus includes a sheave around which an intermediate length of traction rope extends. One run of the rope which is located on one side of the sheave provides a traction run while the run located on the other side thereof provides a free run. The sheave is firmly mounted on a drive shaft which is rotatably mounted on a frame assembly. The frame assembly is provided with an operating member which is rotatably mounted on a support shaft which extends parallel to the drive shaft. The operating member has its opposite ends located adjacent to the periphery of the sheave and each carry a roller having an axis which extends parallel to the drive shaft. One of the rollers is located to engage the traction run of the rope to cause an angular movement of the operating member in response to the tension therein. The other roller is located close to the sheave to hold the traction rope in a groove formed in the sheave as a result of the angular momentum applied to the operating member.

Rope traction apparatus

An apparatus for coiling, storing and uncoiling a wire rope. The apparatus includes a closed container rotatable about an axis thereof and defining a circular space in which to receive the wire rope. A conduit for guiding the wire rope into the interior of the container is rotatably disposed therein in alignment with the axis of rotation of the container. The conduit has an inlet which opens to the exterior of the container, and has an outlet which extends radially and athwart within the container. When the wire rope is introduced lengthwise into the inlet of the conduit, a relative rotation occurs between the container and the conduit, coiling the rope along the sidewall of the container.
