GREAT OLYMPIC HILL IN GARMISCH
Symbiosis between architecture and technical finesse.
The new ski jump in Garmisch immediately impresses with its unique architecture, which already shapes the landscape today. But what lies behind the facade that takes ski jumpers high into the air? The answer: sophisticated technology. The special construction of the facility posed a number of challenges for the planners. In close cooperation with the engineering firm Felka-Hoffmann GmbH, NEW LIFT Steuerungsbau GmbH developed the following customized solutions:
Technical data

| Positioning | Incremental coupling via drive motor |
POWER SUPPLY TO THE CABIN
Cabin power supply via heated conductor rail.
CONNECTION BETWEEN CABIN & ENGINE ROOM CONTROL
Proven connection concept using radio link.
SHAFT COPYING
Incremental copying, whose pulses come directly from the drive motor's encoder. Position correction is performed in the traditional manner using contactless correction switches, which are located at the valley and mountain stations at the appropriate distances.
DRIVE CONTROL
A frequency converter with DCP control was used to enable diagnosis and, if necessary, parameter adjustment of the drive control via remote monitoring.
CABIN & SHAFT DOORS
Use of multi-channel safety circuits with mutual monitoring, which are distributed across the station, cabin, and machine room controls and communicate with each other via wired and wireless connections.
WINTER CONTROL
Proven CUS technology (CUStom specific control) was used to implement this winter control system with de-icing function: » Automatic control of heating for conductor rails, shaft door thresholds, de-icing fluid, and spray nozzles. » Manual or automatic de-icing run (selectable time intervals: 15 min – 2 h). » Monitoring of the de-icing agent fill level.
