Cranes Keep DamProject On

Schedule

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

project.

O

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-

vation date.

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

system.

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

project.

“The cranes have been performing well and have

actually helped the project stay ahead of

schedule,”

he said.

“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

well.”

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
