Abstract
A presently-preferred embodiment of a lift and carrier assembly for a personal-transport vehicle comprises a lifting column, an actuator mechanism adapted to lift the lifting column, a pivot plate rotatably coupled to the lifting column, a platform fixedly coupled to the pivot plate, a cam follower coupled to the pivot plate, and a cam member being fixed in relation to the lifting column so that lifting of the lifting column causes the cam follower to contact the cam member thereby generating a contact force between the cam follower and the cam member. The cam follower is biased so that the contact force prevents the cam follower from being lifted when a weight acting on the platform is below a predetermined value thereby causing the pivot plate to rotate about the lifting column in response to the lifting of the lifting column.
