Abstract: An elevating platform system (1) which can be fixed to vehicles, comprising a platform (2) and a parallelogram shaped lifting gear consisting of two horizontally spaced carrier arms (3,4) for bearing the platform (2), a parallel cylinder (10) for swiveling the platform (2) from a vertical travel position into a horizontal working position and vice-versa, in addition to a lifting cylinder (7) used to lift and lower the platform (2) in the working position thereof. The lifting cylinder (7) engages with a lifting cylinder lever (6) which can be rotated about the pivoting axis (5) of the carrier arms (2,3) and forms a triangle of forces therewith. The first carrier arm (3) is elastically and movingly coupled to the lifting cylinder lever (6) in the direction of lifting and the second carrier arm (4) is connected to the lifting cylinder lever (6) by means of a torsion profile (9).

Abstract: A lifting loading platform (1) to be fastened to motor vehicles comprises a platform (20) and a substantially parallelogram lifting gear (10) having two horizontally spaced-apart supporting arms (12, 14) for carrying the platform (20), at least one parallel cylinder (13) for pivoting the platform (20) about a pivot axis (19) from its vertical position of travel into its horizontal position of operation and vice versa, and at least one lifting cylinder (15) for lifting and lowering the platform (20) in its position of operation. The platform (20) is spaced apart from the one, second supporting arm (14) in a transverse direction and is mounted on the second supporting arm (14) so as to be pivoted about the pivot axis (19) by means of a transversal bar (23) bridging the transverse distance (D).
