The Netherlands


reaches new heights

The first Hitachi Sumitomo SCX A-3

series model in The Netherlands has

been acquired by Gebr. De Koning to

work on concrete structure, water-

works and foundation contracts.


was delivered to the Papendrecht-

based company earlier this year.

The SCX1000A-3 can be used as a

70-, 80- or 90-tonne machine, due to

various configurations from six counterweight parts.

The crane’s dimensions mean that it is easily transport-

able, and can be efficiently assembled and disassembled

when moving between job sites.

Gebr. De Koning also specified the options of a third

winch and a wider skywalk on the 30 m boom for enhanced

safety and easier assembly.

Load Cells Integral to Safe Completion of Crane Boom Lift

Straightpoint load cells were used to facilitate the safe re-

moval and reinstallation of a 300 t crane boom on a 600 t

crane barge in Azerbaijan recently.

Caspian Marine Services

, which operates a fleet of off-

shore marine support vessels serving the offshore oil and

gas industry, was presented with a series of challenges be-

fore executing the project. The gross weight of the crane

boom and centre of gravity was unknown, while the boom

heel pins had never been removed from new and no sup-

porting documentation was available.

Force measurement, load monitoring and suspended

weighing load cell specialist Straightpoint manufactures

equipment capable of providing dynamic information

about loads wirelessly, straight to a PC.

With footprints in the Middle East, Kazakhstan and

Azerbaijan, lifting and marine products provider


offered a solution in Straightpoint’s 300t wireless compres-

sion load cells.

Rigmarine managing director, Mike Duncan,

explained that the load cells were used to con-

duct an engineering and feasibility study prior to

completion of a full scope of work.

“We successfully completed the job without

incident and provided Caspian Marine

Services with a comprehensive turnkey

package, reducing the amount of contractors

required for the project.”

The scope of work included removal of the

boom heel pins with custom-built hydraulic sys-

tems; jacking up of the boom to establish gross

weight and confirmation of the center of gravity;

and reinstatement of the boom after a refit.

Duncan added:

“Straightpoint’s 300t wireless compression

load cells were the perfect component for

the removal and reinstallation project given the

challenging nature of thework and their reputation

for accuracy, safety and versatility on demanding

projects like this.”

Straightpoint’s wireless compression load cells are

available in capacities from 50 t to 500 t and manufactured

from stainless steel and a load centring domed top.

The unique design utilising double o-ring seals on the

load cell ensures they are built for use in the harshest in-

dustrial environments.
