DESCRIPTION
. The 500 Watt searchlight is comprised of a head assembly, a yoke and base
assembly, a Power Supply unit, a remote control panel, a remote ammeter, and either manual or electric
directional controls.
The head assembly housing, the yoke arms and the base are made of aluminum. All components of the
searchlight which are exposed to the weather are painted with epoxy paint. White is the standard color.
The head assembly is supported at its approximate center of gravity by two stainless steel shoulder bolts
extending through holes with bushings in the yoke arms. These bolts engage threaded holes in bosses on
each side of the housing.
The yoke arms are attached to the yoke support plate. The yoke support plate rotates around the spindle
of the base plate on two tapered bearings. A sliding stop plate, located around the base of the rotating
cover allows approximately 380 degrees of azimuth rotation of the searchlight (approximately 190 degrees
either side of dead ahead). The stop is necessary to prevent the electrical cable in the bottom of the head
assembly housing from being severely stressed by wrapping around the yoke. The yoke support plate is
retained on the base by a nut at the top of the spindle. A rubber boot is provided around the base of the
yoke support plate for weather protection. The base is fastened to the ship’s structure with four bolts
through four holes provided in the base plate.
The major components of the 500 Watt Searchlight are described
individually as follows:
