YOUR REQUIREMENTS AND IDEAS – OUR CHALLENGE AND SOLUTION

Whether at the Olympic Games, during masterful acrobatic displays, on bridges over the abyss and even space travel, we bring to life projects that are far from run-of-the-mill thanks our decades of experience and expertise.

We take up the challenge of your customer-specific requests and develop innovative solutions.

We are pleased to outline for you just some of the projects we have implemented.

PLAYGROUND ATTISHOLZ SITE

A large adventure playground surrounded by Swiss industrial history. On the site of the firm Cellulose Attisholz AG which was founded in 1881, a lively and versatile new living space was created in 2018 following a change of use.

For this unusual playground we manufactured and installed a special rope climbing pyramid and other facilities. With its dimensions of 750 cm in height and a diameter of 1040 cm, this pyramid is a highlight against a unique backdrop and a safe challenge for young and old.

OCEAN YOUTH SAILING “VELLAMO” CATAMARAN 

In 2019, following a three-year planning phase, the non-profit association “Ocean Youth Sailing” began the construction of a sea-going high-end catamaran in Switzerland. Following over 20,000 work hours provided by volunteers, the catamaran was first launched on Lake Constance in 2019 and will be transferred to the seas after final testing. 

We are proud to be part of this unique project with our rope technology expertise, our high-tech traps and sheets, our patented rope and anchor lines, as well as various custom-made products.

MÜHLEGG FUNICULAR RAILWAY, ST GALL

The traditional Mühlegg funicular railway was built in 1893 and was the first inner-city transport link. It connects the city centre of St Gall with the Saint George quarter located at a higher elevation.

The railway was last renovated and renewed in 2018. The facilities also needed to be brought up to date with the latest fire technology. A rope handrail that would withstand temperatures of 400 °Celsius was required along the entire length of the tunnel so that passengers could be safely guided to outside in an emergency.

We were able to meet these requirements with our solution; the installation of a 16 mm diameter kernmantel rope made of high-quality aramid yarn.

We are proud to support this traditional and oldest inner-city transport link.

ARIANE ROCKET PROGRAMME 4/5

For the separation tests of the Ariane 4 and 5 rockets, a rope/strap capture system was successfully developed which destroys the energy in a controlled manner during the blast-off tests of the rocket casing. These tests were carried out by ESA and Oerlikon Contraves in Cape Canaveral, USA. A computer program was developed especially for this project, which enabled us to calculate the forces and effects occurring on the capture system.

WINTER OLYMPIC GAMES, VANCOUVER

Based on the plans of Hariri Pontarini Architects, Toronto, Nüssli Schweiz AG erected the Olympic Pavilion in Hüttwilen in 2010 with a floor area of 1,400 m² and a height of 10 m.

Around 50,000 m of Betelon rope with a diameter of 8 mm and a wire rope core of 2 mm were manufactured for the undulating pavilion roof structure.

ST GALL STADIUM

In the stadium of St Gall football club, 4,000 m² of stadium nets were installed in the fan sectors to provide the greatest possible protection for players and spectators. In addition to wear resistance and longevity, the nets also require good transparency between the spectator stands and the pitch to avoid impairing visibility.

In addition, during the building phase of the stadium in 2008, 11,000 m² of fall nets were installed to protect the workers during the construction of the stadium roof.

ROPE-SUPPORTED WORKING METHODS

SWIMMING POOLS AND SLIDES AT SÄNTISPARK

Cleaning and inspection of the 1,000 m long slide network at the Säntispark waterpark in Abtwil, St Gall. Carried out by our specialists for rope-supported works in accordance with the relevant FISAT guidelines.

The rope-assisted access and positioning procedure is always used when work has to be carried out in places that are difficult to access or at significant height.

The rope-assisted access and positioning technology enables work to be carried out in places that would not otherwise be possible, or only using high-cost and material-intensive methods.

ART PROJECT, HOTEL DOLDER ZÜRICH

To implement the “floating rock” art project in the converted Hotel Dolder, a suspension and tension rope with special characteristics was needed. It needed to have high breaking and abrasion resistance as well as be “flame-retardant” (fire code BKZ 4.3). We produced a rope made of Nomex yarn with a diameter of 8 mm and a length of 600 m specifically for this purpose and specified the corresponding suspension points.

TRAVERSINER SUSPENSION BRIDGE, VIAMALE GORGE

A particular challenge, 70 m above the Viamala gorge with a horizontal span of 56 m and a height difference of 22 m, was provided by the Traversiner suspension bridge constructed in 2005. The entire wire rope framework, the corresponding components and the installation of these guy wires and suspension ropes were carried out by our specialists. The bridge continues to be regarded as: impressive, exciting, indescribable and is the winner of a silver medal for architecture.

TUG-OF-WAR WORLD CHAMPIONSHIP IN APPENZELL

On the occasion of the 2012 Tug-of-War World Championship, we manufactured 50 custom ropes made from Usatex, with a diameter of 38 mm and a length of 33.5 m. Whilst ropes for this high-power sport used to be made from hemp, we went one step further and made these ropes from Usatex, a polypropylene spun yarn. Ropes made of this material are barely distinguishable from hemp in appearance, and also offer similar grip and hand-friendliness.

Both the athletes and the organisers were won over by these ropes. The Tug-of-War World Championship was a great success and an unforgettable experience in all respects.

ST. JAKOB STADIUM TRAIN STATION

On the occasion of the 2008 European Football Championship, we covered the entire St. Jakobpark stadium train station and the complete length of the platform with textile nets. This is to prevent personal injury and property damage caused by rioting fan groups throwing stones and bottles. In addition, the underpasses near the stadium were protected with horizontal steel nets.

SUMMER OLYMPIC GAMES, BARCELONA

The Olympic rings with a diameter of 50 m and a weight per ring of 7,000 kg tower over the stage in the Olympic Stadium in Barcelona, and are seemingly freestanding.

To make this possible, we designed a tensioning and holding system that offers safety but with a transparent appearance. This system of wire ropes was manufactured and installed by us in 1992 for the forthcoming summer games.
