Abstract: An improved limit switch actuator for position indicating limit switches in a drive chain take-up for a power and free conveyor system includes an actuator rod which is movable relative to a take-up cylinder. A flag is attached to the actuator rod and is positioned such that, as the actuator rod is moved relative to the cylinder, the flag actuates a series of position indicating limit switches. The actuator rod is linked to a piston in the take-up cylinder via a connecting plate which is rotatable relative to the piston while the actuator rod remains stable. Thus, the piston is free to rotate under the torque effects of a take-up chain without damage to the actuator rod.
