It’s not often you need to know how to set up a rope pulley system – but when you do it is normally an emergency and you need to know how to do it fast!

Vidra Kele brings us these great illustrations as to how to set up various pulleys with increasing ratio strength when the going gets tough. The Z-pulley and “pig-rig” being ideal for those really, really stuck rafts! The last illustration lays out the details so you can set these up. Carabiners can be used instead of pulleys.
