ABSTRACT:
A remote control method and apparatus for use in association with a movable carriage illustrated as a transfer car for handling radioactive materials. The car has a self-contained drive motor energized from a remote power source, and travels in forward and reverse directions in a predetermined path between at least two predetermined operating stations in a closed operating space defined by protective walls. The travel of the car in both directions is automatically halted by means of limit switch means located outside the closed space, to de-energize the power source for the drive motor. A rotary shaft extending through a wall of the enclosed space is rotated in one direction in response to forward travel of the car and in the opposite direction in response to the reverse travel of the car. An adjustable switch means is located on the outside of the chamber wall to halt the car at the predetermined limit position.
