While passengers enjoy the view, the technical components of GARAVENTA’s ropeway systems perform their tasks with precision and reliability. One of the most safety-critical functions is the brake hydraulics. In an emergency, they must respond instantly and flawlessly.

Under extreme weather conditions in particular, the demands increase significantly. In conventional hydraulic systems, the focus is on driving force and power transmission, whereas in ropeways it is on controlled stopping. This requires a hydraulic fluid that reacts immediately and with absolute reliability.

Hydraulic oils for emergency and special cases

With ALPINE COREX POLAR S 370 and ALPINE COREX POLAR S 320, MOTOREX has developed two hydraulic oils that operate reliably across a wide temperature range. These formulations are the result of decades of practical experience and ensure consistent performance even under the highest demands.

The S 320 variant remains fully operational at minus 40 degrees with just 600 mm²/s – well below the pour point of conventional oils. This makes it suitable for other safety-critical applications as well, for example in rescue equipment.

Excellent material compatibility ensures that seals remain flexible and continue to perform their function over the long term. ALPINE COREX POLAR is finely filterable, remains homogeneous and stable – ideal for long-term use.

Reliable partnership from the very start

The Swiss ropeway specialist GARAVENTA has relied on MOTOREX for over twenty years. With the trend toward steeper, larger, and more powerful systems, the demands on hydraulic oils have also increased. Today, every new GARAVENTA installation uses either ALPINE COREX POLAR S 370 or ALPINE COREX POLAR S 320, depending on the technical design.

Even during the initial setup, GARAVENTA fills the safety-critical systems with these proven products. One of the most critical components is the safety brake system, which must activate in milliseconds in an emergency – precisely and reliably. External influences such as temperature fluctuations or humidity cause hydraulic fluids to age over time.

To ensure longterm operational safety, GARAVENTA’s specialists replace the fluids every six to  fifteen years, depending on the location and level of use. MOTOREX supports the entire lifecycle with regular oil analyses. This close collaboration ensures smooth coordination – from condition checks to professional refilling.

GARAVENTA & DOPPELMAYR: Global leaders in ropeway construction

GARAVENTA AG, based in Goldau, Switzerland, has been a pioneer in ropeway system construction for decades. Whether aerial tramways, funiculars, or gondola lifts – the company stands for technical excellence and innovation.

Since 2002, GARAVENTA has been part of the Austrian DOPPELMAYR Group. With over 15,400 completed installations in 96 countries, the group is the world market leader in ropeway construction, offering the highest quality and tailored solutions.

Deployment locations with diverse challenges – from Stoos to Vietnam

In Hong Kong, the historic Peak Tram has been operating since 1888 to Victoria Peak – the city’s highest point – in high humidity. Every year, more than six million visitors enjoy the ride with spectacular views of the skyline and harbor.

In Ha Long Bay, Vietnam, one of the world’s longest three-rope cableways stretches over the sea, where tropical climate, salt spray, and enormous spans present unique engineering challenges.

In Big Sky, Montana (USA), icy conditions prevail, with temperatures as low as minus 30 degrees not uncommon. In Switzerland, GARAVENTA has built iconic projects such as the Schilthorn aerial tramway and the world’s steepest funicular on Stoos.

Whether icy cold or humid and hot, steep or long, MOTOREX ALPINE COREX POLAR hydraulic fluids provide reliable performance worldwide.
