Abstract
A trunnion assembly to interconnect the shank of a hook to a block, like a pulley block, includes trunnion pins that are assembled through the inner bore of a trunnion body and moved outward to extend from the bore into depending side plates of the block assembly and thus rotatably support the trunnion body and lock the pins in place.
