Abstract
A conveyor system comprising a motor power unit, a load carrier and a track along which the motor power unit and the load carrier can move. A vacuum pad is mounted on the motor power unit and extends rearwardly and a vacuum power unit is mounted on said motor power unit for applying vacuum to the vacuum pad. A plate is mounted on and extends forwardly of the load carrier and is adapted to be engaged by the vacuum pad whereby when the vacuum pad engages the plate and is activated a coupling is provided between the motor power unit and said load carrier so that the motor power unit will move the load carrier along the track in either direction.
