ABSTRACT:
A battery-powered cart operatable by a man walking ahead through the medium of a rope attached thereto which is in a forwardly extended state. The rope is connected at the rear end via a sliding member to a spring attached to the cart at a predetermined position in a manner such that the spring urges the rope backwards as it is pulled forwards. The cart incorporates an electric motor, an electromagnetic brake, a battery, and speed-control system electrically connecting with said motor and brake so that the cart moves behind the operator at a speed similar to a man's average walking speed even on a slope, and reduces the speed or comes to a stop as the man slows down or stops because of the slack of the rope.
