  • Patent number: 5282339
    Abstract: An aircraft servicing pit located beneath a surface across which aircraft travel while on the ground is provided with a ladder and a pair of reciprocally retractable handrails on each side of the ladder. Each of the handrails has an inverted "J-shaped" configuration. With the lid open the handrails can be drawn up out of the pit and rotated so that their legs can rest upon the tarmac surface at the edge of the pit. Service personnel utilizing the pit are thereby provided with stabilizing hand grips which enhance their safety when entering and leaving the subsurface chamber within the pit. When the pit is to be closed the retractable handrails are lifted, rotated, and lowered to their fully retracted storage positions.
