Frangible Mast (TBC: no image, no Chinese datasheet, no English datasheet)

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.

Features

• Aluminum alloy sections in an X-shaped frangible frame, light in weight and high in strength
• Standard frangible safety performance: the mast breaks in a controlled way when struck, leaving no rigid obstacle and protecting aircraft, in line with the ICAO frangibility standard
• Suited to outdoor service, with resistance to UV and aging for long exposure to demanding outdoor climates and stable, dependable operation
• Equipment interfaces can be customized to fit approach lighting, communication antennas, meteorological equipment and other airport installations
• Grade 8.8 hot-dip galvanized fasteners throughout, with strong corrosion resistance, long service life and easy installation and maintenance
• Available in a range of installation heights, up to 17.9 m
• Forward-tilting and side-tilting versions to choose from; equipment can be inspected, commissioned and maintained on site without taking the whole mast down, which greatly reduces the work involved
