Cableways Impact Assessment Study - Final Report - saferail.nl

Risk & Policy Analysts
From the data available it is also suggested that Doppelmayr-Garaventa produces
components (although in unknown quantities). Data from the French notified body
STRMTG, states that between 2004 and 2011, 57 Doppelmayr-Garaventa subsystems,
including, drives and brakes, mechanical equipment, electro technical
equipment, cables and cable connections, line engineering systems, rescue systems
and maintenance vehicles (among others) were certified (STRMTG, 2011b).
However, these data should be interpreted with caution as it appears possible that
large manufacturers may in some cases certify parts on behalf of their suppliers.
From data collected from the industry it appears that the manufacture of electronic
devices has only recently become an ‘in-house’ activity for cableways manufacturers
as they were previously manufactured and supplied by external companies.
According to an electronics manufacturer that supplies the cableway industry, in the
past, manufacturers such as Doppelmayr-Garaventa did not produce any of the
electronic equipment for their installations and these were supplied externally.
However, as production now takes place in-house, in Italy Doppelmayr-Garaventa
and Leitner have approximately 80% of the market for electrical components for
cableways while the remaining 20% of the market is divided between subsystem
manufacturers.
Leitner
Leitner currently has facilities in Europe, USA, Canada, India and China as well as 70
sub-companies, such as Leitner Austria, Telefericos y Nieve, Leitner Austria etc.
(Leitner-Poma, nd). Leitner Ropeways technology is designed and engineered at the
main plants in Sterzing (Italy) and Telfs (Austria). In addition, Leitner Ropeways has
recently established a facility in Stará Ľubovňa in north-western Slovakia. The
facility, which includes manufacturing activity and a sales and service office opened
in early 2011 and has 40 employees.
The Leitner supply chain is based on in-house production, subsidiary firms and
external suppliers. Since the 2000 acquisition of Poma by the Seeber Group, Leitner
and Poma have engaged in technical cooperation which has included staff and
subsidiaries from both companies working together and contributing to the supply
chains of both companies. An example of this cooperation is the Leitner installation of
a detachable Gondola at Kronplatz, Italy, which used SIGMA ten passenger cabins
with heated seats (Leitner AG, 2012c).
All mechanical engineering as well as project management and building site
management are done in-house. In-house manufacturing includes stations, mechanical
equipment such as breaks, main and emergency drive units, sheaves and rollerbatteries,
tensioning devices, chairs and grips for all its installation types. Leitner
engineers and produces electronic devices for its ropeway installations. In this regard,
Leitner has developed and produces its own electrical motor (direct drive) to comply
with the specific technical requirements of cableway installations.
Cabins and station covering are supplied by SIGMA. Ropes are supplied by Redaelli,
Arcelor-Mittal, Fatzer and Teufelberger.
