On Friday the 13th of October, Sarens presented their new super heavy-lift crane, the SGC-140.
On their construction yard in Ghent they invited an international audience that could have a look in detail on one of the tallest cranes in the world. This innovative giant crane has a max. Load moment of 140.000 tm and a max. lifting capacity of 3200 mTons.
The crane will go to the TCO project in Kazahkstan and will carry out the installation of various Plant Modules from central locations in the plant for a period of approx. 3 years.
This is not the first Giant crane that Sarens has developed and built.
The first one, similar to this one with a slightly smaller Load moment of 120,000 tonmeters was introduced to the market in 2011 and started its international carreer at the Intel Plant construction in Chandler, Arizona, USA.
Since then the crane, named the SGC 120, successfully executed projects in China (Cosco), Cilicap, Indonesia (G8 E&G), Rabigh, Saudi Arabia (Saipem), Flamanville, France (EDF), Jamnagar, India (Reliance).
Presently the SGC120 is based in Newcastle (UK) loading the Beatrice Jackets (weights from 1000-1150 tons) for the Beatrice Offshore Windfarm onto barges. Read the story HERE
Besides the SGC120, Sarens is building an SGC80 (available in 2018) and an SCG250 (available in 2019). The biggest one, the SGC250 will be used in the construction of the UK nuclear power plant Hinkley Point C.
The new SGC140, demonstrated to the public in Ghent was equipped with a 118 m main boom and with a 44 m diameter ring. Max. length of the main boom can go up to 130 m and optional a Fly-jib can be installed as well.
The Boom pivot points and backmast are supported by 64 bogie wheels, while the counterweight is supported by 32 bogie wheels
To create sufficient stabilizing moment, the crane has 4000 tons of counterweight fitted on the back, which is created by 40 empty containers which can be filled with sand, gravel or grid at the jobsite with a weight of 100 tons each.
During mob./demob these containers are used to store parts of the crane when dismantled.

The crane can lift an impressive 2820 mTons at 50 m radius. The weight of the crane and load is spread via a double rail ring over the subsoil by means of 64 steel support mats, hereby limiting the max. groundload to approx. 25 tons/m2.
The crane is diesel hydraulically driven with a total of 6 Power Packs, giving the crane 100% redundancy.

The new SGC140 gives approx. 45% more lifting capacity at large radii compared to the smaller SGC120.
Three main boom configurations are available: 89 m, 118 m as shown in Ghent and max. 130 m, with optional fly jibs of: 40.5 m, 64.1 m, 87.7 m and max. 99.5 m, whereby the crane can reach a max. height of 230 m.
Based on the SGC120, Sarens and their engineering team improved the design of the bogies, winch systems and power packs, hereby increasing the max. load moment, now resulting in this new SGC140.
In Ghent the crane was assembled and put to work in a period of 6 weeks, but Sarens claims it will be possible in 4 weeks time, after the crews have learned the routine of assembling the crane.
The crane has been designed and built as per EN13000 rules and regulations and tested with 125% proofload
