| SUITABLE
FOR B737 AIRCRAFT FORWARD AND AFT DOORS ON
SERIES 300-500
General specification
The Steps have a fixed lower stairway and top-platform. 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.
Four manual wind-down stabiliser jacks are fitted to the sides of
the chassis-frame.

Chassis-Frame, Steering-Turntable,
Tow-Bar 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 sides of tow-bar.
