  • a machine mount supporting a vertically displaceable slide mechanism and a counterweight;

    a counterbalance system including a first flexible connector suspended from the machine mount and interconnecting the slide mechanism and the counterweight so that a gravitational force acting on the slide mechanism is at least partially opposed by a gravitational force acting on the counterweight;

    a drive system including a second flexible connector suspended from the machine mount and interconnecting the slide mechanism and the counterweight, the drive system including;

    a drive motor operatively engaged along a length of the second flexible connector for vertically displacing the slide mechanism; and

    a compliant connector operating within a limited range of compliance imparts a regulated amount of tension along at least a portion of the length of the second flexible connector between the engagement of the drive motor and the counterweight.
