AVANTI Service Lift for Wind Turbines
3.17 Traction system
The traction system is rack and pinion type. The
system has two motor group working on the
same rack. They are installed on the main frame
of the cabin. Each motor groups has a
centrifugal brake, a gear box, a 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 is guided along the stiles of a
ladder by means of ten guiding rollers.
An inductive sensor detects the presence of the
stile. If the stile is not detected (bigger distance
than setting), control is interrupted, avoiding
derailment of the service lift.
The service lift features two anti-derailment
brackets that prevent derailment if guiding
rollers fail.
