ABSTRACT:
Cable supported hook apparatus provides a U-shaped upward facing opening for transporting a truss. A cam pivotably mounted opposite the opening has a serrated edge opposite a handle. A slot in the opening permits a spring to urge the cam from a released orientation to an engaged orientation with the serrated edge extending through the slot. In the released orientation, a knob retractable spring driven pin extension can extend through a hole in the cam and secure it in place. In use, the handle is first used to rotate the cam to the released and secured orientation. After engagement with the truss, the extension is retracted by the knob which permits the cam to engage the truss. After transportation a release cable rotates the cam to the released and secured orientation to free the truss.
