Problem

Devise an inexpensive and practical system to make it easy for villagers drilling water wells in remote areas to raise the rig's drill head from as much as 15 m (50 ft) below the ground.

Solution

We chose a single-speed winch to accomplish this task. This small, portable winch mounts on one leg of a tripod positioned over the bore hole. The winch's 1:1 mechanical advantage lets one person easily raise and lower the drill head. The low-friction winch handle features a ball bearing grip that efficiently transmits power into the winch.

The winch is constructed of Hardkote-anodized aluminum for wear resistance and durability The Delrin® bearing sleeve is almost maintenance free and requires only occasional cleaning.
