Abstract
A device capable of pulling an object (e.g., a person) by or up a tensioning member (e.g., a rope) is provided. The device can be configured to mate to any location of the tensioning member, and subsequently interface with a rotational power source (such a mechanical drill). Once interfaced, an output of the rotational energy source can be rotationally coupled to a rotating drum of the device wherein the drum is in communication with the tensioning member. With the addition of power, the drum(s) can pull the tensioning member through the device and allow for a continuous force to be applied to an object attached to the device or attached to the tensioning member. The use of such a convenient and low-cost power source allows for an economic, portable, and simple to use device capable of lifting and/or pulling heavy loads.
