Suitable For Aircraft Types :B737-300 Up To Airbus 319 / 320 / 321
General specification
The
Steps have a fixed lower stairway.
The top-platform extends
telescopically (see ** below). The stairway is mounted on a welded steel-section chassis-frame.Construction is robust but is also light in design - saving
time and effort when manually manoeuvring the Steps up to, or away
from, the aircraft.The step treads and top-platform walking-area are surfaced with
grip-faced aluminium tread-plate.
Sliding side-rails with hand-operated spring-bolts at both sides
of the top-platform to facilitate opening the aircraft doors with
the Steps interfaced with the Aircraft.
A pivoting-section is fitted at the leading edge of the
top-platform to compensate with fuselage contours.Rubber buffering is fitted to the top-platform pivoting-section
and to the leading edges of the sliding side-panels.
The standard unit has tubular-steel side /hand rails with a mid-rail and steel-mesh panel, fitted to both
sides of the stair-flight. Full solid-sheet steel panels are fitted
to the sliding rails at each side of the top-platform.Steering is turntable-type through a ball-bearing ring,
controlled by the tow-bar. Tow-bar has a 50mm diameter towing-eye
and grip-handle to assist coupling.
Four wheels with pneumatic tyres, fitted on stub-axles. Each
stub-axle is individually mounted for easy and economical
maintenance.Parking-brake - operating on front steering wheels, actuated by
raising the tow-bar.
A tubular-steel rail is fitted across the front end of the
chassis, providing a conveniently positioned hold for pushing and
pulling.4 stabilising-jacks are fitted to the chassis-frame
2 x quick-release / sprung-retraction type at front end and 2 x
wind-down type at rear end.
Standard Finish
Chassis Frame, Steering Turntable, Towbar and
Front Rail are Galvanised
to ISO1461.
All other sections and panels
are Painted in a single Corporate colour.
High-Visibility (Red
"Day-Glo" painted) Markings are applied to front/rear
chassis, corners and tow bar.
** The top-platform is mounted on a telescoping-section, elevated
via a hand-operated hydraulic-pump and lift-cylinder.
This feature provides either one, two, three, four or five
additional full step-rises when required - To cater for the
variations in height between front and rear door-sills of the B737
- 300 to 900 series-variants, up to Airbus 319/20/21.
Two spring-loaded Pawls, provide mechanical locking of the
telescoping-section at each of the additional full step-rise
positions.
