The Stinar Passenger Stairway, Model SPS-5519 is intended for personnel to board and de-board various aircraft at Air Force and other military and civilian installations around the world. It consists of a commercial truck chassis equipped with a hydraulically operated two-section elevating stairway. The stairway incorporates an aircraft boarding platform at the top of the stairs. The platform provides access to aircraft cabins with doorsill heights ranging from 96 inches (244 cm) to 228 inches (579 cm) above ground level. Hydraulically operated stabilizers at the front and sides of the unit stabilize the passenger stairway when the stairs are raised. The stabilizers enable the unit to withstand winds of 55 mph with the stairs and platform fully raised. Hydraulic power for operating the stairs and stabilizers is provided by a hydraulic pump belt-driven from the truck engine. A separate auxiliary hydraulic power pack is provided for emergency use.
