Sarens has launched the SGC-90 – an electric ring crane designed for projects in the nuclear, construction, and offshore wind sectors.
The crane, named the Little Celeste, was developed in response to market demand for heavy lift cranes with capacities greater than 80,000 tonne/metres. It has a ring diameter of 35 m, a maximum counterweight of 2,700 tonnes, and maximum load moment of 99,000 tonnes.
It can be configured in a variety of ways, with main boom lengths of 100 m, 120 m or 130 m, and a small jib of 200 tonnes. The Sarens heavy-duty and light jib can also be used to reach further or attain a higher hook height. Mobilisation/demobilisation takes between four and five weeks.
While all Sarens’ other SGCs are hydraulic, the SGC-90 can be connected to the electric grid and be fully powered without a traditional fuel source. The Little Celeste can also produce its own energy, recovering and reusing the electricity it generates each time it lowers a load. When connected to the national grid, it recovers all produced energy and feeds it back, reducing energy consumption by up to 40 percent, said Sarens.
Furthermore, it emits no exhaust gases and poses no oil contamination hazard; the crane is maintenance-friendly and reliable, with no hydraulic pumps, filters, or engines.
The Sarens team developed the crane concept in house, performing all calculations and coordinating with different contractors to construct the crane on a tight timeline.
The Little Celeste conforms to the latest crane standards for safety and security, added Sarens. Directive, static, and dynamic overload tests as well as function and safety tests have all been successfully performed and witnessed by the certification company.
A project for the new crane has been lined up for later this year.
