  • Patent number: 6767177
    Abstract: A magnetic lifting system for converting a skid loader into a magnetic lifting apparatus for transporting ferrous metals. The magnetic lifting system includes a platform attachable to a loader of a tractor, an arm member attached to the platform, and a magnet attached to the arm member by at least one chain. A generator upon the platform is mechanically connected to a hydraulic motor that is fluidly connected to the hydraulic system of the tractor to generate electricity. The generator is electrically connected to a controller which is electrically connected to a rheostat for controlling current flow to the magnet. The rheostat is electrically connected to the magnet by a power cable. The arm member is preferably slidably positioned within a receiver tube for allowing distal adjustment of the position of the magnet with respect to the platform.
