  • Load shoring beam for cargo trucks
    Patent number: 4797043
    Abstract: A cargo shoring bar which extends between slotted tracks on the opposite side walls of a truck body. A pair of telescoping tubes have an internal screw and nut mechanism which allows the tubes to be extended and retracted by threaded action when they are turned relative to one another in opposite directions. An end fitting on one tube fits closely in a slot on one track and the opposite slot receives a cylindrical peg on the end of the other tube. Its cylindrical shape allows the peg to turn in its slot so that the tube which carries it can be turned to tightly wedge the shoring beam between the tracks. Optional hoops are fixed at one end to one tube and at the other end to a sleeve fitted closely on the other tube.
