How to make an open-ended pulley system???

Hey.

I'm trying to make a hydraulic operated pulley system, that lifts two pulleys (a bit lige diagraim below).

But I can't figure out how to make the rope/wire. All I can find is the belt/chain feature, wich seems only to work on sketches and has to be a loop?

Can anyone help me here?

Regards
