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.

Abstract: Low-height reversible ratchet tie-down winch for flat decked vehicles. The tie-down winches are adjustably mounted in retainer channels extending along each side of the deck of the vehicle. Each winch is rotatably mounted between the top and bottom walls of its base and tension of the tie-down chain is maintained by a pawl and ratchet. The winch block has a chain pocket to lock a horizontal link of the chain to the chain pocket and a recessed portion engaging a next adjacent vertical link of the chain. The ratchet has a cooperating pocket engageable with a next adjacent vertical link of the chain and completing the chain pocket in the winch block. The chain may be trained through one end or the other of the base for the winch.

Abstract: Adjustable twist lock assembly for locking containers in position on the deck of a flatbed vehicle in which the vehicle has a C-channel extending along each side and opening toward the outside, and the top flange of the channel is at deck level. Each channel has openings in its top flange to accommodate a twist lock to be extended above floor level through a selected opening to enter a container fitting and thereby accommodate the twist lock to containers of varying lengths. The twist lock assembly includes a framework conforming to the inside of the channel and slidable therealong and having an open top to accommodate extension of the twist lock above the channel. The twist lock has an elongated locking head with a depending stud pivotally carried in a lock housing, guided for vertical movement along the framework.
