The present invention provides a device for automatically engaging a cargo container on a platform or transporting vehicle. The device comprises a pair of hooks to vertically restrain the container and a pair of stop plates to laterally restrain the container. The hooks are normally in an engaged position and move downwardly to an unengaged position when a container engages one of the sides of the device. The hooks and stop plates recover their engaged position when the container is properly in place on the platform. A spring or other resilient means extending between the frame and the platform allows the hooks and stop plates to recover their engaged position when the container is on platform or transporting vehicle.
