On request of Fokker Technologies
we developed a full range of "narrow body" telescopic stairs with an easy and reliable height adjustment system, based upon a counterweight system.
The telescopic "narrow body" range comprises: Cabin access, Cargo access, Wing access, APU access, Pylon access and Wheel bay stairs.
This type of stair succeeds hydraulic stairs with a variable slope that are no longer in line with the most actual standards for GSE and national directives. Relevant are EN 1915-1, EN 1915-2 2001 + A1:2009 and EN12312-8:2018.
