  • Patent number: 5120186
    Abstract: A self-contained, full-function, crane attachment for loading machines that is capable of quick release coupling with the standard bucket attachment mechanism of conventional loaders. The attachment comprises a wheel-mounted supporting frame equipped with two hydraulically driven outriggers to provide additional stability and with a control panel pivotally adjustable for comfortable use from the loader's driver seat. A horizontal boom platform is rotatably connected to the supporting frame through a vertical central axle and a generally horizontal hydraulic cylinder for adjusting the relative position of the two, so as to provide a lateral rotational degree of freedom for the platform of approximately 45 degrees in either direction.
