Force-path curve realization device, has cable mounted over pulley movable at fixed point, where point is moved over support pulley

摘要

The device has a cable (204), which is mounted over a pulley (203) movable at a fixed point (202), which is provided with the weights. A point (201) is moved over a support pulley (205). The pulley is positively driven by the cylindrical shaped bolts on a path (208). The variation of upward gradient of the path adjusts the desired funicular forces, which are transmitted by the rope.
