The ALS system is used to raise and lower light Aeronautical and other light fixtures mounted on Communication Towers and Smoke Stacks. The ALS system can raise and lower fixtures mounted 100 meters high. Lowering the fixtures to ground level provides a safe, and efficient way of maintaining them.
The different part numbers are based on the mounting height, fixture mount adaptor, number of contacts, and options such as finish.
See example: ALS-100-34M-8C-GRY
ALS – Tower mount system attached to external of tower or smokestack.
100– fixture height (in feet) (100M in meters).
34M – 3/4″ Male thread fixture stem.
8C – 8 contacts for multiple circuits.
GRY – Options such as Powder Coat painted finish (WHT-White, BLK-Black, GRY-Gray, BRZ-Bronze).
