Maintenance stairs and maintenance platforms

Our mobile maintenance stairs and maintenance platforms are specially designed for work on aircraft and have been used in many countries on the apron and in the hall area for over 35 years. Our current maintenance stairs and platforms comply with the applicable standard DIN EN 12312-8: 2018. Significant innovations are a lower stair inclination, non-slip treads (R13) and the self-closing passage barrier on the platform.

Use our experience if you have special requirements for a maintenance stair.
