摘要：Cable supported hook apparatus (10) provides a U-shaped upward facingopening (28) for transporting a truss (12). A cam (36) pivotably mounted opposite theopening has a serrated edge opposite a handle (19). A slot (34) in the opening permits aspring (63) to urge the cam from a released orientation to an engaged orientation withthe serrated edge extending through the slot. In the released orientation, a knobretractable spring driven pin extension (45) can extend through a hole in the cam andsecure it in place. In use, the handle is first used to rotate the cam to the released andsecured orientation. After engagement with the truss, the extension is retracted by theknob which permits the cam to engage the truss. After transportation a release cable(20) rotates the cam to the released and secured orientation to free the truss.
