Auto lock/Unlock shipping containerMy proposal for :https://grabcad.com/challenges/connect-the-ship-challengeThank you so much for "patrick" has opened up this challenge. and thanks to "GRABCAD" for this opportunity.This is the idea and design of me for this challenge.I hope this could be a solution to the existing problems.I gave name of this tool is "PUSH AND PUSH AUTOMATIC LOCK/UNLOCK CONTAINER"work principle : "when another container or spreader placed on the container, the adjuster will press rotary tooth. automatically twistlock rotates 90 degrees and it will lock the container. That's when container can be lifted and moved. after the container at the desired position and then taken down and laid out slowly, with a tolerance range that I made the adjuster will re-pressing the rotary tooth. twistlock will return automatically rotates 90 degrees for free pisition to remove other container or spreader"
