There are a containers out there and you put them why they don't know I don't no way except one thing. Try other cranes, there is a lot of them and there are ones that are doing anything. I went this problem. Took me a few craners and you make single counter or 2 on top and various sizes in length. Basically, look at other cranes, you are bound to get versions.
If you don't fix I can help as I went through the containers. You load, then unload somewhere.
