Stairway vehicle, in particular a mobile airport stairway

摘要

Stairway vehicle, in particular a mobile airport stairway, having a stairway part (2, 3) comprising a closed stairway housing. In order to reduce the lateral wind forces, the stairway housing at least of the upper stairway part (3) is shaped in cross-section to be favourable in terms of flow, deviating from the rectangular form, in that the side walls at the top and at the bottom are tapered obliquely, different alternatives resulting primarily for the design in the upper region of the side walls. These alternatives include, in particular, a quarter circle shaped design of the upper half of the side wall, a semitransverse oval shaped form of the upper half of the housing and a slope of at least 30 DEG to the vertical direction.
