Abstract
Passenger or freight cabs 9 can roll on bridge rails 24, 25; 54, 55; 64, 65, between a pair of platforms such as an elevator car frame 19, a horizontal transport bogie 41, or a stationary platform 68. The bridge rails may move from a first position to a second position where they are parallel to, coaligned with and overlapping rails on one of the platforms so as to permit transferring a cab, either by individually rotating through corresponding axes passing through each rail, or by rotating a pair of such rails together about an axis passing between them.
