The MahaNakhon tower: the tallest building in Thailand
Two COMANSA tower cranes, the LCL310 luffing-jib model and the 21LC290 flat-top model (now the 21LC335), were used to help build the MahaNakhon tower in Bangkok, the tallest building in Thailand at 314 metres in height and boasting 77 stories.
- The LCL310 luffing-jib crane was located at the base of the building and had a maximum load of 24 tonnes and a free-standing height of 40.4 metres
- Thanks to its 60 metre luffing-jib, its short counter-jib, and its high load capacity, the 24t LCL310 worked quickly and efficiently to get the construction materials ready to be hoisted to the top of the building.
- An 18t 21LC290 flat-top crane was located on the roof of the MahaNakhon tower (now the 20t 21LC335), with a 40 metre jib and a maximum load of 18 tonnes.
- This crane featured COMANSA’s internal climbing system, which quickly and safely elevated the crane, while maintaining two ties to the structure of the building.
- This system meant great savings as only 11 tower sections were required, where an external crane would have needed more than 60 sections to reach 340 metres high.
- This project used an 18t 21LC290 with an optional 110 kW hoist motor, allowing fast speeds to be reached and thus increasing productivity.
- This motor also had a high-capacity hoist cable drum (with 1,280 metres of cable) so that the crane could permanently work with double reeving at its maximum capacity of 18 tonnes.
- The 18t 21LC290 meant the construction of the tower’s central structure was completed in just 20 months.
- The 24t LCL310 and 18t 21LC290 cranes worked on this project for 16 hours a day to meet the project’s demanding schedule.
