Abstract:
1. A method of unloading a wheel supported ambulance cot having a collapsible and extendable base thereon through an acess opening into a cargo area of an ambulance, comprising the steps of: moving an ambulance cot with a collapsed base coupled to a trolley out of a cargo area of said ambulance so that said ambulance cot is cantilevered externally away from said access opening such that the collapsible and extendable base on said ambulance cot is spaced directly above a ground surface unobstructed by other structure; extending said base while said ambulance cot is cantilevered externally away from said access opening so that said wheels engage said ground surface and effect a support of said ambulance cot on said wheels; and moving said ambulance cot on said wheels in a direction until said ambulance cot is generally free of interference from said trolley.
