Abstract
A pulley rack for an exercise machine includes a support frame, an upright extending generally vertically within the support frame, a counterweight having one or more counterweight pulleys, the counterweight moveable in a vertical direction relative to the support frame, one or more guide pulleys mounted to the support frame, a cable end assembly mounted to the upright, and a pull cable having a fixed attachment end connected to the cable end assembly and a pullable end freely passing through the cable end assembly. The pull cable is routed through the cable end assembly, the counterweight pulleys, and guide pulleys such that a force exerted on the pullable end raises the counterweight. A section of the pull cable extends from the pullable end through the cable end assembly and downwardly to one of the guide pulleys mounted below the cable end assembly.
