Abstract
A crawler assembly includes an attachment mechanism that is removably attachable to a stringer. The stringer has a vertical web and a longitudinal axis. The crawler assembly includes a longitudinal slider that is engageable to the attachment mechanism and having a normalizing mechanism disposable in bearing contact against the vertical web for maintaining an orientation of the longitudinal slider relative to the stringer. The longitudinal slider is movable along a direction parallel to the longitudinal axis. The crawler assembly includes a lateral slider that is mountable to the longitudinal slider and is movable along a direction perpendicular to the longitudinal axis. The lateral slider includes a drill bushing. The longitudinal and lateral sliders cooperate to move the drill bushing to at least one predetermined hole location.
