3.16 Top and bottom mechanical
stops
Top and bottom mechanical stops including
buffers are installed on top and bottom of the
ladder to avoid derailment if the top stop/bottom
stop and emergency limit stop switches fail.
3.17 Traction system
The traction system is rack and pinion type. The
system has two motor groups working on the
same rack. They are installed on the main frame
of the cabin. Each motor groups has a centrifu-
gal brake, gear box, pinion and a brake motor.
Each motor brake includes a manual release
lever allowing a manual descent in absence of
electric current.
3.18 Guiding and anti-derailment
system
The service lift has a guiding system based on
rollers. The stiles of the ladder are the guides for
the cabin.
There are ten rollers along the stiles of the
ladder and an inductive sensor that detects the
presence of the stile. If the stile is not detected
(bigger distance than setting), the machine does
not work. It avoids the derailment of the ma-
chine.
The cabin has two anti-derailment brackets
preventing the derailment of the machine in case
of failure of the rollers. This prevents the
machine from going out of the ladder.
