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 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. Unit powered by a 24V 220 Ah maintenance-free AGM battery, which can be charged by a solar-charging system allowing complete ramp independence.
