Not quite...The rope you pull needs to go around a top pulley then a bottom pulley. The other end of that rope needs to be attached to the upper pulley, but not rotate around it. The lower pulley is attached to the load...That is, the pulley not the rope is attached to the load. The arrangement will reduce the load by 50%. Additional cascaded pulleys will give you an aditional reduction.Posted: 03 Oct 2005 12:00 PM

It is pretty much rope and pulleys. The more pulleys you put the rope through, the greater the mechanical advantage.
