In short, this is often referred to as a 'bolt-on hauling system'. It's used by rescue agencies. The main 'load line' is rigged seperately and can be used for raise or lower. Many organisations run the tail of the load line through a 'progress capture device' at the anchor - think big gri-gri - so that, as the load comes up, rope is also pulled through this device by another operator. This can then be used to hold the load during haul system resets or, if the load has to be sent back down, to lower.

For climbing, it would be very unusual to consider setting up a 'bolt-on' system and far more sensible to utilise the fact that the rope is already running through a belay device that can act as the 'top pulley'. If you belay your second with a gri-gri, then a prusik and biner are all you need to set a safe z-haul.

Looking forward to ODH's pic...
