Cranes beaconing

The cranes beaconing is mandatory when the building site is located near an airport or heliport, or air navigation routes.

Even if in most cases the cranes are considered as temporary obstacles, the cranes beaconing remains compulsory.

Obstruction lights are also necessary on cranes even if the machines are not in use (nights and week-ends).

Crane beaconing implementation

The number of obstacle lights and their arrangement on the crane shall be such that the structure is indicated from every angle in azimuth.
If one of the beacons set up on the crane is not visible from one direction, one or more aircraft warning lights shall be added on it, in order to insure the beaconing of its complete contour.

Low intensity obstruction lights have to be spaced at longitudinal intervals not exceeding 45 meters, and the medium intensity lamps at intervals not exceeding 900 meters.

Thanks to their design, our obstruction lights for cranes are especially tailor-made for the crane operators issues. Indeed, their aluminium structure is very light:
0,6 kg for the LIOL B, 5 kg for the MIOL AB.

Our crane beaconing kit

PROMIC created for all cranes operators, a crane beaconing kit to help them upgrading to obstruction lights standards.
The crane beaconing kit includes:

  • 3 low intensity obstacle lights type B.
  • 3 quick connectors.
  • 1 backup power supply cabinet.

The lightness of the LIOL B 32 cd, which weigh less than 1 Kg, makes the installation of the beacons easier on the jib and counter-jib of cranes.
Thanks to the quick connectors, the obstacle lights wiring is simplified, and gives an important time-saving to the crane operators. The emergency power cabinet insures a minimum of 12 hours autonomy.

Cranes beaconing less than 45 meters

Upper 150 meters, even if the crane is marked with red and white paintings, it has to be equipped by diurnal and nocturnal beacons.
Two beaconing levels medium intensity type AB are recommended: one level at the top, the second at 50 meters.
At 100 meters, a low intensity obstacle light LIOL B will complete the installation.

Cranes beaconing between 45 and 105 meters

At 200 meters, you will need to add a level of low intensity obstruction light type B so the crane can be pointed out every 50 meters.
Every additional 50 meters, a level of medium intensity AB or low intensity B shall complete the structure.

Cranes beaconing of 150 meters

The cranes painted red and white have to be fitted with a medium intensity obstruction light MIOL B 2.000 cd (red flashing lights), and a low intensity obstacle light LIOL B 32 cd (red steady burning light) is advised on the middle of the crane.
For unpainted cranes, a medium intensity aircraft warning light MIOL AB 20.000 cd with flashing lights (white for day / red for night) is necessary.
In case of power cut, an emergency power cabinet insuring 12 hours of minimum autonomy is necessary.

Cranes beaconing of 200 meters

At 200 meters, you will need to add a level of low intensity obstruction light type B so the crane can be pointed out every 50 meters.
Every additional 50 meters, a level of medium intensity AB or low intensity Bshall complete the structure.
