Hello my name is***** look forward to assisting and am very sorry to hear that you are having this problem.
You are going to want to lubricate the trolly itself rather than just the chain.
Do not use oil or WD-40 if you do wipe it off right after, You would want a lubricant like this:

This should help with it dragging, it should also help if it is making a lot of noise.
