Construction company Bouygues-Thai is using two Linden Comansa tower cranes to help build the MahaNakhon tower in Bangkok, Thailand.
The MahaNakhon Development is by PACE Development Corporation. It will be 314 metres tall with 77 floors, including a hotel, a shopping area and the luxury apartments. According to the company it is already the tallest building in Thailand.
The two tower cranes on site are an 18 tonne capacity 21LC290 and a 24 tonne capacity jib LCL310 luffing job model. Both cranes were supplied to Bouygues-Thai from Smart, an official distributor of Linden Comansa in Thailand.
The LCL310 has been erected at the base of the building and has been on site since 2012. It has a free standing height of 40.4 m, 60 m luffing jib and short counter jib. Work for the crane includes unloading construction materials for the first floors of the tower. Prior to this, the model was used to construct the MahaNakhon Cube, a seven floor luxury retail centre in the same area of the MahaNakhon tower.
The 21LC290 flat top is working on top of the MahaNakhon tower. It has been configured with a 40 m jib. Initially, it was erected on fixing angles with a freestanding height of 60.7 m. It has an internal climbing system, meaning the crane only needs 11 mast sections to reach the height of 340 m, the manufacturer said. The 110 kW hoist motor on the 21LC290 offers a maximum speed of 228 metres per minute.
The cranes are being used on site 16 hours a day, from 6 a.m. to 10 p.m. under the Bangkok Metropolitan Administration guidelines. The project is due for completion in 2016.
