A latching mechanism useful in the raising and lowering of luminaires mounted to a support ring and positionable at an upper end of a high mast, the invention comprehends a latch pin capable of articulating attachment to the support ring for preventing damage to latching structure and for reducing the potential for jamming as the latch pin engages latch cams on raising of the support ring. The latch pin is particularly configured with a ball-shaped swivel joint capable of reducing the potential for damage to the pin and associated structure by permitting the support ring to tilt if canted during a lowering operation. The latch pin is further configured with a nose portion of a diameter sufficient to center the latch pin relative to latch cams on raising of the support ring, thereby to reduce the potential for jamming.

Latching mechanism for high mast lighting system

A method and apparatus for cable support and guidance for use on a high elevation outdoor lighting system in which luminaires, for servicing and inspection, are lowered from an operating position at the top of a pole to a position at the base of the pole. A series of rollers are mounted at the pole top to support and guide the passage of a luminaire, elastomer-jacketed power cable which, during raising and lowering of the luminaires, moves in a path that extends vertically through the interior of the pole, over the roller arrangement and vertically to the luminaires on the exterior of the pole.
