Abstract: A cargo restraining device for a palletized load including a platform for receiving a pallet with a load of cargo thereon, and a vertical frame at one end of the platform. A handle is pivotally secured to the frame and connected to a horizontally-extending member which is movable to place it in frictional contact with a floor or supporting surface. When the pallet is placed on the platform, it can be locked in place by a serrated member which engages a cross-tie of the pallet. To lock the pallet and platform to the floor, the handle is pushed downwardly while at the same time pushing the frame toward the load. Movement of the handle, which pivots about a hinge pivotally connected to the frame, moves the horizontally-extending member into contact with the supporting surface and at the same time lifts and tilts the platform, which adds an augmented downward force on the horizontally-extending member in contact with the supporting surface.

In the other direction, the restraining member is overridden by the cargo out of each position of the restraining member structure between the lever and the restraining member.

Abstract: The cargo retainer comprises a floor contacting member having an upwardly facing load bearing surface which is adapted to project forwardly beneath the cargo load and an upright member secured to the floor contacting member in spaced relation from the forward end of the floor contacting member for engaging with the face of the cargo load.

The wheels engage with the floor for wheeled maneuvering of the retainer only when the forward end of the floor contacting member is raised relative to the floor. Further, the upright member is vertically extendible to accommodate load heights exceeding the normal height of the retainer unit.
