The benefit of cable cars for tourism

“In new tourist projects, cable cars are being used strategically to boost the provision and stimulate tourism. Cable cars that combine urban and tourist benefit are especially popular,” POMA Marketing Manager Carole Mancini says. In-house, the French cable car manufacturer distinguishes between three categories of tourist cable cars, although these can also be combined. First: cable cars in amusement parks. One example here would be the Beauval zoopark. It offers a unique experience in France

for the 1.5 million annual visitors who enjoy fantastic views over many areas of the park, aboard gondolas with glass flooring. Second: Providingaccess to a tourist destination. The cable car in Yen Tu (Vietnam), for example, is notable here. It runs up a temple mountain and is used by over two million passengers per year. Third: The cable car as an attraction in itself. This is the case for example in Tlemcen (Algeria). Here the cable car actually serves as a classic urban mode of transport for everyday use, but thanks to the tourists it transports 3,500 people per day at weekends – significantly more than on work days.

“All over the world, (urban) tourist cable cars are used by around 300,000 passengers per year,” Mancini highlights the potential: “a ticket costs 30 euros on average and the yields are accordingly high.” We must also emphasise the tourist benefit of urban public transport, such as on the cable car in Namur, which opened in 2021. This now allows many residents to travel from the suburbs to the city centre in only four minutes; timetables have therefore been extended, in order to benefit daily commuters.

Example: Teleferik Alanya (Turkey)

By way of example for the world’s many city tourism facilities, SI Urban takes a closer look at two cable cars in Turkey. One is the Teleferik Alanya from Italian cable car manufacturer LEITNER, which is located in the Turkish region of Antalya.

The Mediterranean climate, scenic attractions and historical heritage make Alanya a popular tourist destination, accounting for nine percent of the Turkish tourist industry. “The Alanya cable car has been operated by the eponymous holding company since 2017. The aim is to stimulate and improve the quality of tourism.

The cable car considerably strengthens the transport network in the area of the historic Alanya Castle, a UNESCO world cultural heritage site,” LEITNER Marketing Manager Gotthard Schöpf says.

The cable car offers a fast transport service (one gondola every 19 seconds) and is equipped with 14 8-person gondolas. The track, which is around 900 metres long, has a transport capacity of 1,130 people per hour.

This all makes the cable car in Alanya a popular mode of transport – especially for tourists. Consequently, within only one year, the number of passengers increased from 851,800 (2018) to 1,035,800 (2019). Most passengers come from Russia, Germany, Ukraine or Denmark.

Cable transport

 

Cable transport is a broad class of transport modes that have cables. They transport passengers and goods, often in vehicles called cable cars. The cable may be driven or passive, and items may be moved by pulling, sliding, sailing, or by drives within the object being moved on cableways. The use of pulleys and balancing of loads moving up and down are common elements of cable transport. They are often used in mountainous areas where cable haulage can overcome large differences in elevation.

 

Common modes of cable transport

 

 

Aerial transport

 

Forms of cable transport in which one or more cables are strung between supports of various forms and cars are suspended from these cables.

 

Cable railways

 

Forms of cable transport where cars on rails are hauled by cables. The rails are usually steeply inclined and usually at ground level.

 

Other

 

Other forms of cable-hauled transport.

 

History

 

Rope-drawn transport dates back to 250 BC as evidenced by illustrations of aerial ropeway transportation systems in South China.[12][13]

 

Early aerial tramways

 

An aerial tramway used in mining.

The first recorded mechanical ropeway was by Venetian Fausto Veranzio who designed a bi-cable passenger ropeway in 1616. The industry generally considers Dutchman Adam Wybe to have built the first operational system in 1644. The technology, which was further developed by the people living in the Alpine regions of Europe, progressed and expanded with the advent of wire rope and electric drive.[14]

The first use of wire rope for aerial tramways is disputed. American inventor Peter Cooper is one early claimant, constructing an aerial tramway using wire rope in Baltimore 1832, to move landfill materials. Though there is only partial evidence for the claimed 1832 tramway, Cooper was involved in many of such tramways built in the 1850s, and in 1853 he built a two-mile-long tramway to transport iron ore to his blast furnaces at Ringwood, New Jersey.[15]

World War I motivated extensive use of military tramways for warfare between Italy and Austria.[14]

During the industrial revolution, new forms of cable-hauled transportation systems were created including the use of steel cable to allow for greater load support and larger systems. Aerial tramways were first used for commercial passenger haulage in the 1900s.[12]

 

The first cable railways

 

A gravity incline in use in 1955 at Llechwedd quarry in Wales. Empty wagons are arriving at the top of the incline – the winding drum is in the shed in the background A test run on the Westside and Yonkers Patent Railway Company line in 1867 Hallidie's Clay Street Hill Railroad, the first successful cable railway running at street level

The earliest form of cable railway was the gravity incline, which in its simplest form consists of two parallel tracks laid on a steep gradient, with a single rope wound around a winding drum and connecting the trains of wagons on the tracks. Loaded wagons at the top of the incline are lowered down, their weight hauling empty wagons from the bottom. The winding drum has a brake to control the rate of travel of the wagons. The first use of a gravity incline isn't recorded, but the Llandegai Tramway at Bangor in North Wales was opened in 1798, and is one of the earliest examples using iron rails.[16]

The first cable-hauled street railway was the London and Blackwall Railway, built in 1840, which used fibre to grip the haulage rope. This caused a series of technical and safety issues, which led to the adoption of steam locomotives by 1848.[17]

The first Funicular railway was opened in Lyon in 1862.[18]

The Westside and Yonkers Patent Railway Company developed a cable-hauled elevated railway. This 3½ mile long line was proposed in 1866 and opened in 1868. It operated as a cable railway until 1871 when it was converted to use steam locomotives.[19]

The next development of the cable car came in California. Andrew Hallidie, a Scottish emigre, gave San Francisco the first effective and commercially successful route, using steel cables, opening the Clay Street Hill Railroad on August 2, 1873.[20] Hallidie was a manufacturer of steel cables. The system featured a human-operated grip, which was able to start and stop the car safely. The rope that was used allowed the multiple, independent cars to run on one line, and soon Hallidie's concept was extended to multiple lines in San Francisco.[21]

The first cable railway outside the United Kingdom and the United States was the Roslyn Tramway, which opened in 1881, in Dunedin, New Zealand. America remained the country that made the greatest use of cable railways; by 1890 more than 500 miles of cable-hauled track had been laid, carrying over 1,000,000 passengers per year. However, in 1890, electric tramways exceeded the cable hauled tramways in mileage, efficiency and speed.[22]

 

Early ski lifts

 

The first surface lift was built in 1908 by German Robert Winterhalder in Schollach/Eisenbach, Hochschwarzwald and started operations February 14, 1908.[23]

A steam-powered toboggan tow, 950 feet (290 m) in length, was built in Truckee, California, in 1910.[24] The first skier-specific tow in North America was apparently installed in 1933 by Alec Foster at Shawbridge in the Laurentians outside Montreal, Quebec.[25]

The modern J-bar and T-bar mechanism was invented in 1934 by the Swiss engineer Ernst Constam,[26][27] with the first lift installed in Davos, Switzerland.[28]

The first chairlift was developed by James Curran in 1936. The co-owner of the Union Pacific Railroad, William Averell Harriman owned America's first ski resort, Sun Valley, Idaho. He asked his design office to tackle the problem of lifting skiers to the top of the resort. Curran, a Union Pacific bridge designer, adapted a cable hoist he had designed for loading bananas in Honduras to create the first ski lift.[29]

 

More recent developments

 

More recent developments are being classified under the type of track that their design is based upon.[citation needed] After the success of this operation, several other projects were initiated in New Zealand and Chicago. The social climate around pollution is allowing for a shift from cars back to the utilization of cable transport due to their advantages.[30] However, for many years they were a niche form of transportation used primarily in difficult-to-operate conditions for cars (such as on ski slopes as lifts). Now that cable transport projects are on the increase, the social effects are beginning to become more significant.[31] In 2018 the highest 3S cablecar has been inaugurated in Zermatt, Switzerland after more than two years of construction. This cablecar is also called the "Matterhorn Glacier ride" and it allows passengers to reach the top of the Klein Matterhorn mountain. (3383m)[32]

 

Social effects

 

The La Paz cable car system in Bolivia is both the longest and highest urban cable car network in the world.

 

Comparison with other transport types

 

When compared to trains and cars, the volume of people to transport over time and the start-up cost of the project must be a consideration. In areas with extensive road networks, personal vehicles offer greater flexibility and range. Remote places like mountainous regions and ski slopes may be difficult to link with roads, making cable transport project a much easier approach. A cable transport project system may also need fewer invasive changes to the local environment.

The use of Cable Transport is not limited to such rural locations as skiing resorts; it can be used in urban development areas. Their uses in urban areas include funicular railways,[33] gondola lifts,[34] and aerial tramways.[35]
