ABSTRACT:
An apparatus for providing access to vehicles and containers on a pair of railways or thoroughfares. The apparatus is comprised of a raised walkway between the pair of thoroughfares having a tracking platform movable thereon. Pivotally attached to and carried by the tracking platform is a turret. Carried on the turret and hinged thereto is a bridge that is rotatable in a vertical plane. At the end of the bridge is a cage pivotally attached to the bridge so that the cage remains horizontal when the bridge is rotated vertically on the turret. The bridge and cage are dimensioned so that, when the turret is rotated such that the bridge is directed between and parallel to the thoroughfares and the bridge and cage are raised, the apparatus is entirely out of the clearance envelopes of the thoroughfares.
