ABSTRACT:
Material handling car and track assembly, the assembly comprising a car having wheels mounted thereon, and a track having two parallel rails, the wheels being adapted to roll on the rails to facilitate movement of the car along the track, a metal slider extending from an underside of the car and lengthwise of the car, and opposed linear motors mounted beween the tracks and spaced from each other to define a gap between the motors, the slider being daapted to pass through the gap, the motors being operative to act on the slider to impart thrust to the car, the motors being oriented such as to substantially eliminate magnetic atraction between the mtors and the car. The invention further contemplates opposied magents mountede beween the tracks and spaced from each other to define a gap between the magnets, the slider being dapted to pass through the gap between the magnets, the magnets being operative to act on the slider to impart braking to the car, whereby to decelerate the car.
