  • Patent number: 5431470
    Abstract: A machinery lift assembly includes an L-shaped tubular support member having a first leg thereof connected to a beam of a pivot joint. The pivot joint defines first and second cantilevered portions of the beam. A hydraulic cylinder is pivotably connected between the first cantilevered beam portion and the first leg of the support member to cause the beam to pivot relative to the support member upon activation of the cylinder. The second cantilevered beam portion is fitted at its end with a device for attachment to a machinery component. The beam and attachment device may thereby be inserted into confined spaces to remove or replace machinery components installed therein.
