The RB-6 beacon consists of the following assemblies: a head assembly,
hub and shaft assembly, box assembly, and motor assembly. These
assemblies are described below.
The head is made of aluminum castings. The forward and aft sections of
the housings are hinged to allow access to the lamp for replacement, or to
the lens for cleaning, or replacement.
Clear and green lenses are mounted 180 degrees apart, and each head is
factory preset to an elevation of 5 degrees above the horizontal.
The rotating hub is mounted on a shaft which passes through the top of the
motor box, and is supported by bearings at the top and bottom of the box.
A heavy duty aluminum casting with a cover plate houses the motor and
electrical equipment, and is vented to prevent an accumulation of excess
heat. Access to the interior of the housing is gained by removal of the four
cover plate screws and the plate.
The 50/60 Hz motor is geared to drive the shaft at 12.5 (Export) RPM when
operating at 50 Hz. This output shaft is connected to the hub assembly that
rotates the lamp heads.
This subsection describes options for the RB-6 rotating beacon (Export
Version).
See Figure 2-2. An L-810 obstruction light is available for mounting on top
of the beacon. The obstruction light lights when one or both of the beacon
lamps fail to operate. A fault circuit is also available. The fault circuit can
be wired to a horn or light to serve as an alarm indicating that one or both
of the beacon lamps have failed.
