Abstract
A redundant locking device is disclosed with two adjacently positioned latching arms each including an L-shaped hook portion selectively engageable with the container for securing it to a trailer or truck transport apparatus. The two latching arms are positively driven by a powering means such as a hydraulic or pneumatic cylinder which urges both latching arms toward the engaged position for securement of the container. Powering is provided through a lateral link member which is movably secured such as by a universally flexible ball and socket joint with respect to each latching arm for powering movement thereof responsive to activation of the driving air cylinder. The locking device can be secured to the side of a transport vehicle with the cylinder located between the retracted position of the arms or beneath the vehicle with the arms along the side of the vehicle and the drive cylinder positioned therebeneath.
