Aircraft safety wash rack

Abstract

The aircraft wash rack has a supporting frame being attached to the hangar ceiling and a safety track being specifically constructed for the particular aircraft shape is attached to the supporting frame. In order to construct the safety track, the aircraft is placed in the position where the cleaning occurs. A story pole is moved about the aircraft outer surface edges to measure the height of the track above the aircraft as well as to determine the position of the track on the aircraft upper surface. The track usually is about 2 feet or so from the wing edges. After this information is determined, the safety track is constructed and attached to the supporting frame. A roller guide is attached to the track with a rope therefrom which is further attached to a rope adjuster. This is attached to the maintenance person who would be wearing a harness. The length of rope between the person and the track would be on the order of about 10 feet and would remain essentially constant because the guide follows the above track. As the person moves over the aircraft surface, the roller guide would move to keep up with the person. Because of the closeness, a fall off the aircraft would result in a drop of only a few inches and at the most a foot. This invention is particularly suitable when the inventory consists of one type of aircraft, but could be easily adapted to other aircraft shapes because the track could be removed and another attached.
