skyscraper of 314 meters and 77 floors, is
already the tallest building in Thailand, and
from 2016 will feature a hotel, a shopping and
luxury apartments to be called 'The Ritz-Carl-

The MahaNakhon project, developed by the leading
developer of luxury Thailand, PACE Development Corpora-
tion Plc., Is being built by Bouygues-Thai, with the aid of
two Linden Comansa cranes.
At the base of the building is a LCL310 24 t luffing jib
crane model. With maximum load of 24 tons and standing
height of 40.4 meters, the first job was building the CUBE
MahaNakhon a luxury mall located in the same ground as
the MahaNakhon tower.
Since then, the work is fundamentally handling all sup-
plies coming to site, sorting and raiseing them up to the
top floors of the tower.
With its 60 meter luffing jib, its short counter-jib, and
its large capacity, the LCL310 works quickly and efficiently
in the work preparing the materials that have to be el-
evated to the top of the building.
On the roof of the tower MahaNakhon a Linden
Comansa 21LC290 18 t flat-top crane with 40 meter boom
and a maximum load of 18 tons is placed. Initially, the
crane was mounted on foot foundations allowing a free-
standing height of 60.7 meters.
As the tower was gaining in height, the 21LC290 was
also rising thanks to the internal climbing system, which is
tied to the building structure.
The SMART service team, together with Bouygues-
Thai, supervised the climbing crane 21LC290 making the
first moves of climbing together. It was climbed in stages
to reach the final height of 340 meters, climbing 4 stories
In order to work with maximum efficiency, 21LC290
was equipped with the optional engine that delivered
110 kW lift, which reaches speeds of up to 228 meters per
Also, this engine has a high capacity hoist rope drum
(1,280 meters of cable) manufactured by Lebus, so that
the crane can work double forwarding and maximum ca-
pacity of 18 tons permanently.
The cranes were delivered with the Bouygues-Thai,
corporate colour orange and worked 16 hours a day, from
6 am to 10 pm under the rules of the Bangkok Metropoli-
tan Administration (BMA), to meet the demanding project
