there are 2 ways, as far as i know
the one i used: crouch and push the cart behind .. that requires some patience, but it works .. then push the other
other, more 'normal', way

:
when you enter the room and walk straight ahead, you'll encounter a barrier out of crates and a door behind .. there's no way you could jump over that barrier .. but u can try to walk through one of those machines ..
there should be one without a cart underneath its .. pipe
