  • Loading device for goods vehicles
    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.
