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.
“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-
