Custom Drive Solutions
The right solution perfectly planned The Doppelmayr/Garaventa Group is the ideal partner for implementing your ropeway project. We always provide you with the right solution. Because the drive concept as well as the ropeway itself is specifically planned and exactly tuned to requirements. We attach great importance to delivering a total package that both addresses local circumstances and meets technical requirements. The focus is on ecological and economic efficiency. At Doppelmayr/ Garaventa, we rely exclusively on the use of proven industrial components in order to satisfy the standards we set ourselves in terms of the quality and availability of our installations.
Questions to be asked when selecting the drive include the following: What kind of ropeway system will it be? What are its technical specifications (vertical rise, average gradient, etc.)? Where will the drive be located (e.g. in the village center, in the top station)? What are the location-related requirements (noise, environment, etc.)? How accessible is the drive station (by truck, possibility of crane deployment, etc.)?
Three different drive concepts, each with their re spective strengths and benefits, enable continuousmovement ropeways to be planned to suit the customer’s precise needs: AC drive, Doppelmayr Sector Drive (DSD) and Doppelmayr Direct Drive (DDD). The specialists from Garaventa employ the same individually tailored approach when planning drive concepts for reversible aerial tramways and funicular railways. Doppelmayr/Garaventa customers can rely on optimal advice and support for their ropeway projects. When deciding on the right drive concept, consideration is given to all the components that determine the most cost-effective and best suited drive type. Individual planning is key.
We are fully aware of our responsibility towards customers and partners – before, during and after the purchase of a ropeway installation. That’s why our customer support is there to assist you through out the entire lifetime of the product. The customer support specialists are available 24/7 to answer your queries regarding maintenance and service. The service team’s many years of experience and the ex-stock availability of all components for all Doppelmayr drive concepts ensure short response times when needed.

AC motor with gear unit The AC motor is the lightweight among the various drive systems. It impresses in particular with its low installation and repair requirements – even in the case of drive stations with difficult access. The AC motor is suitable for all ropeway geometries
and types, and provides top performance even in steep terrain. Its lightweight standard components – motor and gear unit – make it the least expensive option in terms of initial outlay.
Benefits Least expensive in terms of initial outlay Suitable for every ropeway geometry (even very steep installations) Straightforward installation and repairs, even in the case of ropeways with difficult access
Doppelmayr Sector Drive – DSD The Doppelmayr Sector Drive (DSD) is a permanent magnet synchronous motor developed by Doppelmayr. It has a long and successful track record and uses cutting-edge frequency converter technology. The drive comprises four or eight independent sectors, depending on output. It is mounted on a two-stage planetary gear unit. Thanks to the inde pendent sectors, limited operation is possible at the
press of a button in the event of motor or converter failure. The DSD is comparatively lightweight, achieves a very high level of efficiency and is also ideally suited to steep ropeways and to all installation types. The DSD motor is water-cooled, which makes it suitable for ecofriendly heat recovery.
Benefits Very high efficiency Suitable for every ropeway geometry (even very steep installations) Limited operation possible without additional measures in the event of motor/ converter failure

Doppelmayr Direct Drive – DDD The Doppelmayr Direct Drive (DDD) is a gearless drive concept, which makes it particularly low-vibration and low-noise as well as energy-efficient and maintenance-friendly. The low weight of the individual components used in the modular ring construction make the drive suitable for helicopter installation. It can also be transported using a standard truck. The DDD uses a hermetically sealed permanent magnet synchronous motor, which is water-cooled. This enables ecofriendly heat recovery. The incorporation of water cooling also dispenses with loud
fan noise, which has a very positive impact on the environment. In direct comparison, the DDD has the lowest noise emissions – it is whisper-quiet. The continuous stator windings are encapsulated in special epoxy resin to provide perfect protection against external influences. As this drive concept does not require a gear unit, no gearbox oil is required and the associated maintenance costs no longer apply.
Benefits Exceptionally low noise emissions Exceptionally low maintenance requirement as there is no gear unit Very high efficiency
Drive concepts for reversible aerial tramways and funicular railways Each project and every customer requirement result in a solution that is made to measure. Reversible aerial tramways or funicular railways often entail largescale projects, which are planned and engineered entirely for the specific application – one-off solutions perfectly tuned to customer wishes. The same goes for the respective drive concepts. The core elements of an aerial tram or funicular drive are the drive
bullwheel, the gear unit and an efficient AC motor. The specialists at Garaventa draw on many years of experience and solid expertise when precisely tailoring their designs. Performance, configuration and execution are developed in close collaboration with the customer to arrive at a solution that perfectly addresses requirements and the circumstances of the new ropeway installation.
