SFS – Single Flight Height Adjustable Stairs.
The SFS range is a highly popular product providing solutions to some of the most common access needs during aircraft maintenance from general access during ground handling operations to specific solutions such as PAX door access, Cargo bay access and cockpit window access. With full customizable options of stair width, platform configuration, height range and towing capability we supply a fully customized product to suit all requirements.
The NIJL SFS range combines a single-flight staircase with height adjustment to provide practical access across a wide range of aircraft maintenance applications.
Its single continuous stair flight provides a simple, direct route to the working platform, while hydraulic height adjustment allows the platform to be positioned accurately for different aircraft types, maintenance configurations and working heights.
Available with different stair widths, platform sizes, mobility systems and aircraft-specific access packages, the SFS can be configured for applications including passenger doors, cockpit windows, cargo doors and general aircraft maintenance access.
The modular design allows each unit to be adapted to the aircraft geometry, operating environment and maintenance task, providing a versatile solution where height flexibility and direct platform access are required.
