An apparatus for operating a hand chain of a hand chain hoist. A housing forms a void through which a hand chain of the hand chain hoist moves in either a lifting direction or a lowering direction, to lift or lower, respectively, a load corresponding to the hand chain hoist. A sprocket or two pulleys are movably mounted within the housing. A drive, such as a right angle drill, operably moves the sprocket and/or the pulley and thus moves the hand chain, selectively, in the lifting direction or the lowering direction. A line, a cord and/or another suitable structural element connects the housing to an overhead structure. Another line, cord and/or other suitable structural element connects or holds the housing with respect to a ground surface or another fixed structural element, and an operator can use this line, which can be adjustable, to tighten and hold the overall chain hoist drive time of this invention.
