Transferring passengers up stairs into an aircraft can pose a particular challenge for airlines crews, especially those looking to provide exceptional service.

With a weight capacity of 350 lbs (160 kgs), the S-Max Aviation gives you crews the ability to carry passengers up narrow stairways and within the cramped confines of most popular commercial passenger aircraft.

The S-Max Aviation offers several unique benefits, including pivot rollers for maximum manoeuvrability, robust construction, chest harness and adjustable handles.

As with other stairclimbers manufactured by AAT, the S-Max Aviation is equipped with safety brakes and and puncture-free tires.
