Langkawi Sky Bridge

Langkawi Sky Bridge is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Langkawi Sky Bridge rather than just read about it. In short: Langkawi Sky Bridge is a 125-metre (410 ft) curved pedestrian cable-stayed bridge in Malaysia, completed in 2005. The bridge deck is 660 metres (2,170 ft) above sea level at the peak of Gunung Mat Cincang on Pulau Langkawi, the main island of the Langkawi archipelago in Kedah.

Reference excerpt

Langkawi Sky Bridge is a 125-metre (410 ft) curved pedestrian cable-stayed bridge in Malaysia, completed in 2005. The bridge deck is 660 metres (2,170 ft) above sea level at the peak of Gunung Mat Cincang on Pulau Langkawi, the main island of the Langkawi archipelago in Kedah. The Langkawi Sky Bridge can be reached by first taking the Langkawi Cable Car to the Top Station, where an inclined lift called SkyGlide takes visitors from the Top Station down to the bridge. The bridge was closed in July 2012 for maintenance and upgrading. The reopening was put off several times, but it partially reopened in February 2015. The bridge is now fully accessible.

Design and construction

Design and layout The curved cable-stayed bridge is 125 meters (410 ft) long and nominally 1.8 meters (5.9 ft) wide, in five 25 m (82 ft) sections: a wider curved central section connected on each end symmetrically to a curved section followed by a straight section. It has steel railings as well as steel wire meshes on both sides of the bridge. It was designed by Peter Wyss as a curved walkway to maximise the viewing experience, providing shifting perspective as a visitor walks along the bridge. The walkway, formed of steel and concrete panels set on top of an inverted triangular truss, connects two hilltops at Gunung Mat Chinchang. The first 25 m (82 ft) of the bridge is straight, followed by three curved 25 m (82 ft) sections, then a final straight 25 m (82 ft) section. At each end of the walkway, the bridge has a 3.6m-wide triangular viewing platform that serves as resting and viewing areas for visitors. The curved bridge deck is suspended by four pairs of front-stay cables, connected to outrigger hanging points located at the ends of the three curved 25 m (82 ft) sections, in a semi-fan array from the top of an 81.5 m (267 ft) high single pylon. The curved bridge deck hangs with its center of gravity directly below its point of suspension at the pylon head and with the top of the deck at an elevation 660 m (2,170 ft) above sea level. The pylon is anchored onto a concreted pad set at an elevation of 604.5 m (1,983 ft), and its tip reached 686 m (2,251 ft) above sea level. It is tilted from the vertical, at angles of 12° and 2° in two planes, and stabilized by two main back-stay cables, anchored into opposite hillsides. The two ends of the curved bridge deck are connected to two triangular viewing platforms on opposite hilltops. The bridge is designed to carry a up to 250 people.

Construction The bridge was pre-fabricated in segments and lifted to the top of the mountain using Russian Kamov helicopters. The entire bridge was then assembled in its current position beside the pylon. Helicopters were also used in the erection of the two triangular end platforms, the pylon, and the initial central segment of the deck. Because of instability in the deck segment, the remaining deck segments, of which there were fourteen, were assembled using more conventional working cable and winch system, with a winch at each end platform and the working cable strung to the pylon. The bridge roughly cost $1.2 million to construct. The bridge was constructed in 12 months between August 2003 and August 2004. It was opened to the public in February 2005.

2012 upgrade In July 2012, the bridge was closed for maintenance, upgrading and structural strengthening. The whole structure would be of stainless steel, and when it is finished, it would have sections of glass walkway in the wider central curved section so that visitors may look down the valley from where they stand, and an inclined elevator or lift called SkyGlide that brings visitors from the top station down to the bridge. The bridge reopened in February 2015, although access was for a time still limited as the SkyGlide was not finished until December 2015.

SkyGlide

An inclinator called SkyGlide and a new platform were built linking the Langkawi Cable Car's Top Station and the Sky Bridge, taking passengers down to the Sky Bridge. It opened in December 2015. The SkyGlide cabin can accommodate 12 passengers or 1,050 kg (2,310 lb) load per trip, and the ride lasts about two minutes. The ticket for the SkyGlide is sold separately at the Top Station. A cheaper alternative to the SkyGlide is for visitors to walk 10–20 minutes along a steep and less secure mountain track between the Top Station and the Sky Bridge.

Popular media The last scene of the 2006 Indian movie Don: The Chase Begins Again was filmed here. The 2007 Tamil movie Billa starring Ajith Kumar was also filmed here.

Worked examples

Example 1 — a first encounter with Langkawi Sky Bridge

Start with the simplest possible case. Write down what Langkawi Sky Bridge claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Langkawi Sky Bridge before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Langkawi Sky Bridge ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Langkawi Sky Bridge

In research: Langkawi Sky Bridge appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Langkawi Sky Bridge in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Langkawi Sky Bridge is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2005 establishments in Malaysia, Buildings and structures completed in 2005, Buildings and structures in Kedah, so understanding it makes those chapters shorter.
In everyday life: Look for Langkawi Sky Bridge outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
