Calculating Torque for Rack and Pinion Lifting System

[QUOTE="Tom.G, post: 6108287, member: 581973"] Another lifting approach is use a wire rope (cable) or a continuous chain at each corner, with a pulley/sprocket at the top of the corner columns. The motive force is still applied at the bottom with either a drum to wind the wire rope or a sprocket to drive the chain. The advantage of this approach is its cost effectiveness and greater parts availability. For stability, I also recommend diagonally cross-bracing the corner posts. Or at least a frame around the top (and bottom if possible) with strong gussets. Cheers, Tom [/QUOTE]
