I cannot get through the conveyer belts in the transit area as I constantly arrive at a belt coming towards me with boxes on. It has a yellow laser that I need to run/crouch to get under, but a box always arrives and pushes me back and it's very frustrating

If anyone could advise how they got through this I'd be grateful

If I'm not mistaken there should be little side areas adjoining the conveyor belt that you can go to and wait until the box goes by.

I actually managed to do this tonight. It was penultimate conveyor belt that was holding me up, but I managed to run/crouch under, then roll over just in time.
