发明名称 Redundant lift beam assembly
摘要 A lift beam assembly for lifting heavy objects having a main support body and a pair of lift arms pivotally suspended at each end of the body. The free end of each lift arm has an aperture which is sized to fit over and engage lifting trunnions or bosses provided on the object. A latching mechanism is provided for each lift arm whereby through the latching mechanism, each arm can be independently moved from a first outwardly extended, open position to a closed, vertical lifting position. The latching mechanism includes a locking arrangement to hold the lift arms in their desired position. The lift assemblies can be arranged for redundant operation whereby two assemblies are suspended in crossed, perpendicular arrangement from a single lifting hook. An elongated tool is provided for engaging the latching mechanisms so they can be operated from a remote location either above or below the lift assembly.
