  • Patent number: 5211265
    Abstract: A scissor-type snowmobile lift comprised of first and second cross members, rails, a pair of scissor members, two mounting brackets, a lower cross member and a hydraulic cylinder. The rails and first and second cross members form a lift frame. The first and second cross members are spaced so they contact the bellypan of the snowmobile. The rails are spaced so that the snowmobile track lies between the rails. The snowmobile is placed or driven onto the lift frame. As the lift frame is raised, the first and second cross members contact the bellypan and the rails contact the frame or running boards of the snowmobile, causing the raising of the snowmobile while keeping the skis and tracks free of the lift frame for maintenance and repair.
