Abstract
A hold down device is provided to engage and hold down adjacent ends of containers on a flat bed vehicle. The hold down device includes four twist locks being two longitudinally spaced pairs of twist locks, each pair being two laterally spaced twist locks which hold down each end of a container. The twist locks are spring loaded so that they will be continuously biased into a protruding operative position, yet capable of being automatically recessed when a long container is set down over the hold down device. A connecting apparatus is provided to inter-connect all four twist locks for simultaneous movement between a locked and unlocked position and an over-center spring is provided to hold the twist locks in the currently selected position.
