Cranes Keep DamProject On
No fewer than 23 cranes from Potain’s special-application, luffing jib, topless
and top-slewing ranges combine to offer broad lifting coverage on huge
ne of the largest groups of Potain cranes
at work in Asia is helping the Xayaburi dam
in Laos stay on schedule as the eight-year
project enters its second phase. The 23
Potain tower cranes began arriving at the job site in 2012
and are expected to stay on site for another three or
four years, as the project builds towards its 2020 acti-
The success of the highly ambitious dam is strongly
dependent on reliable performance from the fleet of
Potain tower cranes, and to date that performance has
been exactly as expected.
There are two huge Potain MD 1600 cranes installed
on the job that are playing the lead role in the enormous
concrete pouring operation. The cranes have been con-
figured with 80 m of jib and have a maximum rated
capacity of 64 t.
Roller Compacted Concrete is poured by the cranes
at rates of up to 250 m³ per hour and the MD 1600 cranes
are working with Potain’s top-belt concrete placing
The top-belt system acts as a concrete conveyor belt
that extends 25 m beyond the jib, enabling each crane
to pour up to 600 t of concrete per hour at a radius of
up to 105 m.
Main contractor on the project is Thai company, CH.
Karnchang PCL, and the Potain cranes were supplied to
the company by S.B. Siam, the exclusive dealer for the
cranes in Thailand.
Verawat Siriboonrit, sales manager for S.B. Siam, said
his company remains closely involved with the
“The cranes have been performing well and have
actually helped the project stay ahead of
“We’ve been training a lot of people associated
with the job and also keeping a steady supply of
parts heading up to the location. The job site is
working 24/7, so it’s imperative that the cranes
stick to their tasks and also fit in with the overall
construction schedule. So far they’ve performed
Alongside the two MD 1600 cranes are a mix of 21
other Potain cranes. The cranes are strategically posi-
tioned to give every square meter of the job site at least
3 t of lifting capacity.
The most popular choice for the job site is the MC
310K12, and there are 11 of these positioned across the
project. These units have a 12 t maximum capacity, and
are fitted with jib lengths ranging from 50 m to 70 m,
and with working heights ranging from 50 m to 100 m.
Alongside these are four MCT 385 units, which have
a maximum capacity of 14 t and have been configured
with jib lengths of 75 m. They are working at heights
that range from 50 m to 135 m.
There are also two MC 205B units, which have a
maximum capacity of 10 t. They are working with jibs
