Abstract: Cable supported hook apparatus provides a U-shaped opening suspended upwardly open for transporting a truss. A cam is pivotably mounted on one end of a slide which can translate and move the cam through a slot in the opening and engage a truss within. A spring is arranged to bear against projections from the slide to translate the cam. A spring loaded lock is arranged to secure the slide outwardly from the slot before engaging a truss. After a truss is engaged the lock can be disengaged to permit the spring to drive the cam against a truss to secure the truss for transport. After the truss is in place a cable can withdraw the slide and release the truss.

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.

Abstract: This adjustable dock apparatus uses a planar body pivotally attached to the edge of a dock and horizontal movement of a planar extension slideably attached to and coplanar with the body to close the space between a truck trailer and the dock. A first set of power driven actuators rotate the body between vertical and horizontal, and a second set of actuators moves the extension. Inductive spaced apart sensors on the extension outer edge detects the trailer and stops the bracketing second actuators when a predetermined distance from the trailer to space the extension and trailer and match the angle between them.
