Improving Worker Access to Aircraft

As the work environment changes, so do the ways maintenance workers access aircraft when they're working above ground level.

All of the limitations of the above mentioned systems have been eliminated with the introduction of JLG's Fall Arrest Platform System. The upper railing of the specially built platform has a stainless steel wire rope secured at six points along three sides. On entering the platform, a worker attaches the lanyard from his or her body harness onto the moveable transfastner device. The unique feature of the transfastner is its ability to move across the wire rope attachment points without interruption allowing the worker to remain attached at all times.

When maintenance personnel have elevated the boom to the working position, they can leave the platform and work up to six feet away from it while being protected by the personal fall arrest system. And, the transfastner lets them move the full 270 degrees around the platform without stopping to change the lanyard anchor every time they reach a wire rope attachment point. Along with complying with OSHA 1926.502 fall protection regulation, the Fall Arrest Platform System also meets CAL/OSHA article 6, appendix C specification.

JLG offers the Fall Arrest Platform System on most of the diesel and dual fueled powered telescopic and articulated boom lifts. These boom lifts range in heights from 40 ft. up to 150 ft. There are additional aviation specific options designed to work with the Fall Arrest Platform System that add to creating an efficient, effective and safer work environment. Most notable is JLG's Soft Touch System that reduces the chance of accidental contact resulting in property damage. The Soft Touch option features a suspended padded rail, which surrounds the lower part of the platform and is connected to proximity sensors. If the suspended rail comes into contact with the aircraft, the operator is alerted and all machine functions are de-activated. The platform rails are also wrapped in padding to provide additional protection Halogen work lights mounted on the basket, a tool tray in the basket and cold weather start kits are among a few of the many options available.

Along with the new Fall Arrest Platform System JLG has introduced the 740AJ Fall Arrest articulating boom lift. JLG redesigned an existing articulating boom to meet other aircraft maintenance requirements. Added counterweight and puncture-proof foam filled tires were added so the 740AJ meets industry jet blast standards of 80 mph steady winds and 90 mph gusts. Four-wheel drive and four-wheel steering add to the machine's maneuverability.

The platform can be extended vertically to 74 feet and horizontally to 51 feet, 10 inches, so it is capable of reaching every point on the tail, wings and fuselage of most aircrafts manufactured today. A useful option that adds to the 740AJ's utility is an on-board air compressor with air lines running inside the boom to the platform. The compressor permits pneumatic powered hand tools such as rivet guns and wrenches to be operated without using a separated compressor and eliminates air lines hanging down from the platform. There is also an 110V outlet in the platform for electric powered tools. Both the compressor and electric outlet are powered by an on-board generator.

With the new Fall Arrest Platform System and the 740AJ, the jobs associated with aircraft inspection and maintenance and airport maintenance can become more efficient and effective.
