Can you use door hinges? They’re cheap and very heavy duty.
Also, I saw an interesting thing to assist raising a heavy trap door. I thought I saw it here but I just searched and couldn’t find it. Anyway this smart fellow used rear glass lift supports to assist opening the door. They’re cheap and they act as a stop as well.
