TBD Owen Holland design and manufacture a range of passenger stairs including this parallelogram type suitable for servicing a wide range of aircraft with a doorsill height range of 1.9m-5.6m.
Our towable parallelogram passenger stairs (TPS) are available in 3 sizes, TPS 1941, TPS2435 and TPS3056. These parallelogram types boast treads pivoting on full length stringers. Built from a robust all steel construction, the stair flight is mounted on a welded steel chassis sub frame. An automatic lift-mast locking mechanism fitted to protect against hydraulic failure when elevated.
The stair treads, mid landing and top platform walking area are surfaced with a grip-faced aluminium tread plate to assist passengers in all weather types. Sliding doors on the top platform with hand operated spring-bolts at both sides of the top platform enable the opening of the aircraft doors with the passenger stairs connected to the aircraft. The leading edges are fitted with rubber buffering to protect against damage to the aircraft.
