Abstract
A ramp stowable beneath the floor of a vehicle is normally power driven between retracted and extended positions. The drive, or propelling, mechanism for the ramp provides for the ramp to be manually disconnected from the propelling mechanism for manual extension and retraction in the event of a power failure in the system.
