Frame auto-lock

My idea has motors with batteries and remote control in the corners . Batteries should be periodically recharged from the mains The ability to set the frame in a variety of containers (adjustment middle) The process of loading containers is added to the capture and installation of the frame. But there is no human intervention No modifications of the container Holes for attaching to the vehicle are open There are openings for manual unlocking of the container (If dead batteries and no access to the mains) I don't know how much moving the containers during transport on the vessel. Maybe you can make an automatic battery charger using the weight and instability of the containers - the batteries will be recharged when the containers will move. Containers be as close as possible to each other. There is no cost for revision of the container or spreader (No need for a special loader) container loader installs and removes the frame After removing the frame, the container is used as before Frame locks are installed simultaneously to the container Each lock is set to its frequency. In case of failure (no signal from the lock, open locks) signal supplied by the remote control. Possible welding of the lugs, for a better fastening of the frames to each other in the stack The locking mechanism is equipped with limit switches Monolithic axis linking the upper container and lower container https://d2t1xqejof9utc.cloudfront.net/screenshots/pics/d221c3b426221836cf4cc82286d84d94/large.jpg Step 1 Spreader sets the first container on the platform (ship or land transport) Step 2 Spreader Frame captures Step 3 Spreader frame descends and captures the container Step 4 Sets the container Spreader frame to another container. Step 5 Electronic locks the frame closed, the lock Spreader - opens. Step 6 The lock on the frame, installed on the upper platform of the container opens Repeat step 2 - 6 Step 7 The last (top container) the Spreader captures and installs without a frame.
