The
current "single haul" system is comparable to the
operation of a mechanical clothesline because both
cabins must travel along the cable loop at the same
time, with each cabin ending its trip at the
opposite side. As a result, both cabins must be
operational during non-peak travel times and both
must be taken out of operation to perform
maintenance on any one part of the system. In
contrast, the dual haul system being installed,
which enables the cabins to travel independently,
will allow for greater scheduling flexibility during
both rush and off-peak hours. It will also permit maintenance on one
side while the other remains operational.
Furthermore, an automatic rescue system will use
auxiliary power sources in the case of an outage to
return cars to the nearest station, eliminating the
need for rescue equipment.
-
Increased reliability.
-
Service life extended 30 years.
-
Each tramway line can be operated independently
in event of: malfunction, preventive
maintenance, rush hours and other peak and
off-peak demands.
-
Integrated rescue system will ensure that in the
event of a malfunction of any component or power
failure, the cabin cars will be brought back to
the nearest station using redundant power and
motive systems, avoiding high level emergency
rescue operations.
-
Reduced downtime for maintenance and repairs: one lane can be shut down for repairs while the
other lane can provide uninterrupted service.
-
Reduced maintenance and operating costs.
-
Improved quality of travel, providing a smoother
ride under high winds due to new wide track rope
gauge.
-
State-of-the-art technology brings higher levels
of energy efficiency.
