As /u/interstate-15 said, it was unlikely it was actually overloaded, it just fucked up the levelling system causing it to sit lower than the actual door opening. Their comment explains it better than I could. I knew it couldn't have been their weight alone (which is why I mentioned my surprise as the lift is rated to 1500kg) but I didn't understand how she could have actually broken it.  The levelling issue makes way more sense!  My own guess on weights would be about 380kg for the whale and 300kg for the husband. They are quite literally the biggest I've ever seen in real life and I was amazed either of them could leave their home without a wall being removed and the use of a crane! The entrance to the lift was almost 2 metres wide and her flab smooshed against the edges (both sides!) as she slowly reversed her way in. I'll say one thing for her, she was a fucking good driver to get herself so well centred while she backed herself up!! I'm stunned that her husband was still walking too. I would have expected him to be using a scooter as well as his legs could barely move past each other to take a step. It was horrible but fascinating watching them both. Awww thanks! It sucks being sick and disabled but at least I didn't do it to myself! I'd rather be like this than fat though!!
