Adjacent the terminal is a swing support post including means for accommodating swinging about a vertical axis.

An elevating post is disposed intermediate the swing post and parking station for adjusting the elevation of the free extremity of the walkway and includes a gear rack arrangement for swinging the walkway laterally relative thereto. A cab is suspended from the free extremity of the walkway by means of a parallelogrammatic linkage which is coupled with the swing post and operative to maintain the cab floor level irrespective of the elevation of the free extremity of such walkway. The cab includes a laterally opening doorway for mating with the entry door of a vehicle parked in such parking station upon lateral swinging of the walkway.
