ABSTRACT:
This invention provides a drive system for moving wheeled structures longitudinally along a supporting track. The drive system includes an element extending longitudinally below the track and having an upwardly inclined ramp portion, a main portion extending in parallel with the track and leading from the ramp portion, and a downwardly extending portion leading from the main portion. A drive system is adapted to drive the element such that the main portion moves at a speed equal to that at which the wheeled structure is intended to move and a gripper mechanism is provided for attachment to the wheeled structure to engage with the element. The gripper mechanism includes a gripper device moveable vertically upwards from a rest position to an engaged position, and including an engagement device for meeting the element at the ramp portion so that as the wheeled structure moves along the track the element moves the gripper device into the engaged position where the gripper device is locked on the element to move with the element.
