Abstract
A self-contained crawler assembly is engageable to a stringer and is adapted to position a drill bushing along the stringer for performing machining operations. The crawler assembly includes a longitudinal slider, a lateral slider and a controller for regulating operation of the longitudinal and lateral sliders for positioning the drill bushing at a hole location. In a further embodiment, the crawler assembly may include a longitudinal friction drive which is directly engageable to the stringer and which is operative to move in a direction parallel to the stringer.
