The ABT-2045-E is a reliable and electrical powered towable Aircraft Passenger Boarding Stairs designed for enplaning/deplaning passengers to/from an aircraft parked in the airport apron area.
The stair assembly is mounted on a towable chassis and consists of a pivoted lower flight and a telescopic upper flight. The stair can be tilted and extended to achieve the best elevation in its working range.
The unit has four (4) hydraulically-operated vertical stabilizers to provide stability.
Mechanical restraint devices are provided to prevent the stairs from lowering and retracting.
A mechanical parking brake is automatically applied when the tow bar is lifted.
