Frangible Mast

Overview

Airsafe frangible masts are safety support members developed for airport navigation aid installations. They can be built to order and are used to mount approach lighting, communication and navigation antennas, meteorological instruments, wind cones and similar equipment. The frangible construction carries its load with reliable stiffness and stable operation under normal conditions; when an aircraft, a vehicle or other equipment strikes it, the mast breaks and collapses as designed, which limits the secondary damage a rigid structure would do to whatever struck it and keeps the remains from standing as a rigid obstacle. It gives the airside and the related operational areas of an airport a safe, dependable way to support equipment.
