NMC Wollard International TLPH 310

The Wollard Airport Equipment Co. TLPH-310 Passenger Stair is a self-propelled, diesel-powered boarding stair engineered to service a broad range of transport aircraft with precision and reliability. Designed to accommodate aircraft door sill heights from 76 inches (193 cm) to 114 inches (289.5 cm), the TLPH-310 delivers safe, stable passenger boarding across multiple fleet types.

Its telescoping A-frame structure provides smooth and accurate stair height adjustment, while the parallel stair design ensures that the stair treads and upper platform remain level at all operating heights. This consistent geometry enhances passenger comfort and safety during boarding and deplaning operations.

Aircraft protection and passenger security are central to the TLPH-310’s design. Adjustable handrails (wings) on both sides allow fore and aft manual adjustment to match aircraft door configurations, and rubber cushion bumpers on the handrails and platform edges minimize the risk of fuselage contact damage. Illuminated steps and a lit upper platform support safe operation during nighttime or low-visibility conditions.

An independent hydraulic system powers stair raising and lowering, stabilizers, and steering functions, delivering responsive and reliable performance. The unit is diesel engine powered with a conventional rear-wheel drive transmission, providing dependable traction and maneuverability on the ramp. Hydraulic power steering further enhances handling, while the welded steel frame chassis ensures structural durability in demanding airport environments.

For maintenance flexibility, an optional emergency hand-operated hydraulic pump allows manual operation when needed. With its robust construction, level parallel stair design, and comprehensive safety features, the Wollard TLPH-310 is a dependable boarding solution built to keep aircraft turnarounds efficient and secure.
