A practical method of lowering the PVC pipes into the borehole is to use a rope (see picture). One end of the rope is attached to the drill rig and the other end is wrapped three times around the pipe to form a self-closing loop. The rope is used to prevent the casing and screen slipping into the borehole while adding a new length of pipe.

Most people do not think of wire rope as a machine, but it is. It is a machine composed of precise, moving parts, all designed to bear a very definite relation to one another. In fact, some wire ropes contain more moving parts than many complicated mechanisms. A six strand rope consisting of 36 wires per stand with
