The SPS-3518 Passenger Stairway offers a safe and reliable way for
passengers to board and disembark aircraft.

tinar designed the SPS-3518 in the
1970s as larger, wide-body aircraft
sill heights approached 19 feet.
Now, the stairway is used all over
the world and offers features to suit many
diverse types of operations.
" The SPS-3518 has a minimum floor
height of 96 inches to 228 inches, which
allows the stair unit full-service capabilities
of almost all midsize to wide-body aircrafts all the way up to the B-747, "
says Jason Johnson, vice president
of business development for Stinar.
The stairway comes with several
key features. The 48-inch stairways feature
embossed diamond tread steps and stainless-steel handrails.
Dual hand controls, proximity sensors, a cab-mounted operator's camera for
visual height adjustment and an electronic
overspeed controller assist operators when
maneuvering the stairs into position.
A PTO-driven hydraulic system, a PowerPack electrical backup, poly fenders and
toolboxes, an extending platform and a front
swivel bar bumper also come standard.
The SPS-3518 provides numerous safety
features, too, including lock valves mounted

These safety
features exist to assure customers there will be no chance of mechanical issues while using the stairs. The lock
valves keep the cylinders from moving inadvertently in an extended position while the
A-frame locking mechanism prevents the
A-frame from descending should a hydraulic part fail.
The stairway is used globally by a range
of customers.

North Pole to down under, FBOs and MROs
