  • Patent number: 7367770
    Abstract: A retractable tail-lift for a vehicle comprises a lifting mechanism (30) for lifting and lowering a platform (50), and guiding rails (21) in which the lifting mechanism (30) with one vertical carriage (32) each is suspended and can be slidably displaced between a working position located behind the vehicle and a travelling position located below the vehicle, wherein each carriage (32) has a front guiding element (40a) with an upper sliding member (42a) and rear guiding element (40b) with a lower sliding member (42b). The front guiding element (40a) is attached from above onto the carriage (32) and is arrested on the carriage (32) at right angles to the direction of attachment, and the rear guiding element (40b) is attached from below onto the carriage (32) in an opening (32.3) of the carriage (32) and is arrested on the carriage (32) at right angles to the direction of attachment.

  • Patent number: 4147261
    Abstract: A loading device for a goods vehicle comprises a lifting platform which can be raised to the height of the loading surface and then pivoted into a vertical position to form a tail gate. The rear end of the lifting platform can also be tilted downwardly when the lifting platform is at road level or a loading surface height. The lifting platform is supported and operated by two hydraulic rams in conjunction with two lifting arms and two guiding arms. The rams are hingedly connected with the lifting platform differently so that both serve to raise the platform and one serves to pivot the platform to vertical position after the platform has reached loading surface height.
