ABSTRACT:
The latest in a series of wheelchair lift improvements is provided, the basic lift structure on which the improvements are made being the type utilizing a step configuration, the individual panels of which, being hinged together, are simply extended into a geometrical plane rather than a step structure. The resulting platform is then elevationally adjusted by the driver to commute the platform, and a wheelchair victim on the platform, between the curb and bus floor level. The improvements include the hydraulic drive for deploying the mechanism between step and platform mode, the safety barrier structure which defines an extension of the platform to the curb level when it is dropped from its safety barrier mode, a safety locking mechanism and a stablizing chain.
