摘要
The device comprises a ramp unit mounted on a support and pivotally movable relative to this support between a position where it is swung to one side of the steps and a position where it ascends the steps. The pivot connection between the ramp unit and support cooperates with a unit (5) for compensating for the weight of the ramp unit.
