CONTROL TECHNIQUES GIVES TRAIN A LIFT
One of the most powerful lifting systems in the world has been
installed by the SNCF at its new “East European
Technicentre”. A synchronized lifting line can lift a
complete TGV train-set – some 200 metres long and weighing 386
tonnes – in just 10 minutes to an accuracy of a millimetre, thus
allowing maintenance of the running gear.
This represents a world record in terms of the accuracy / volume
/ weight ratio and was achieved with the use of Control Techniques
Unidrive SP AC drives in conjunction with LSMV asynchronous
brake-motors from sister company Leroy-Somer, who was responsible
for leading the project.
The new Technicentre, located on the outskirts of Paris, is the
maintenance headquarters for the TGV Est, which links Paris to 21
cities in eastern France as well as 11 other destinations in
Germany, Luxembourg and Switzerland. Journey times have been
drastically reduced – Paris Strasbourg, for example, is reduced
from four hours to just two hours 20 minutes.
There are a total of 26 jacking stands fitted along the
maintenance line, each fitted with an 11kW Unidrive SP drive,
incorporating three plug-in modules; SM Applications module to give
powerful on-board programming, SM Interbus for drive to drive
synchronization and communications and an SM Universal Encoder
module for position feedback from the jacks. The Leroy-Somer
LSMV motors were provided with absolute encoders for accurate
positioning and fitted with brakes for
security.>>>>>>>
