Linden Comansa cranes build Thailand’s tallest tower

BANGKOK, August 12, 2015

Two tower cranes from Spanish manufacturer Linden Comansa are helping build Thailand's tallest skyscraper in Bangkok.

The MahaNakhon tower  -- 314 m tall and with 77 floors -- is already the tallest building in Thailand and from 2016 will house a hotel, a shopping area and the luxury Ritz-Carlton Residences, Bangkok. When finished, the MahaNakhon tower will amaze everybody with its exceptional and spectacular "pixelated" facade, said a statement.

MahaNakhon Development, by Thailand’s leading luxury developer Pace Development Corporation, is being built by Bouygues-Thai.

The two cranes were sold to Bouygues-Thai by Smart Company, the official distributor of Linden Comansa in Thailand.

A luffing-jib LCL310 24t model is located at the base of the tower since 2012. With maximum load of 24 tonnes and a freestanding height of 40.4 m, its first duty was the construction of the MahaNakhon Cube, a seven-floor luxury retail centre in the same area of the MahaNakhon tower which opened in 2014.

Since then, its work consists of unloading all construction materials arriving to the jobsite, arrange and distribute them on the ground as well as lift them up to the first floors of the tower. Thanks to its 60-meter-long luffing jib, its short counterjib, and its high load capacity, the LCL310 24t works quickly and efficiently preparing on the site all the materials that have to be lifted to the top of the building.

On top of the MahaNakhon tower stands a flat-top crane, model 21LC290 18t, with 40 m jib and maximum load of 18 tonnes. Initially, the crane was erected on fixing angles with a freestanding height of 60.7 m. As the tower was gaining height, the 21LC290 18t was also getting higher thanks to Linden Comansa’s internal climbing system, which is tied to the structure of the building. This internal climbing system climbs the crane quickly and safely while maintaining two ties to the structure, and saves economic costs as it only needs 11 mast sections, when a external crane would need more than 60 mast sections to reach the height of 340 m.

Smart trained the Bouygues-Thai’s erectors team how to climb the 21LC290 18t, by doing the first set of manoeuvres together. It took a total of 18 climbs to reach the maximum height of 340 m, climbing four floors each time.

To work with the greatest possible efficiency, the 21LC290 18t is equipped with a 110 kW rated  hoist motor, which reaches speeds of up to 228 m per minute, allowing high productivity and efficiency as the loads are moved very quickly. In addition, this engine has a high capacity cable drum (1,280 m of rope) manufactured by Lebus, so that the crane can permanently work with double trolley and full capacity of 18 tonnes.

The 21LC290 18t crane started with the construction of the core structure of the MahaNakhon tower in September 2013 and completed it only 20 months later, in April 2015. This successful construction process was due to the good planning by Bouygues-Thai, the great collaboration between the service teams of Smart and Bouygues-Thai and certainly the great quality and performance of the Linden Comansa 21LC290 18t tower crane.

The cranes LCL310 24t and 21LC290 18t, delivered with Bouygues-Thai’s corporate orange colour, are still working tirelessly 16 hours a day under the Bangkok Metropolitan Administration guidelines, to meet the demanding schedule of the project. - TradeArabia News Service
