SGC-90 giant electric crane new from Sarens
10 November 2020
International heavy lift and transport specialist Sarens has announced a new 100,000 tonne-metre super heavy lift ring mounted crane.
The SGC-90 joins its three larger siblings in the SGC (Sarens Giant Crane) series, the 250,000 tonne-metre SGC-250, the 140,000 tonne-metre SGC-140 and the 120,000 tonne-metre SGC-120. Nicknamed “Little Celeste”, the new giant is fully assembled and has been undergoing testing at the port in Ghent, Belgium. It can have a load up to 1,650 tonnes on the hook.
Target applications include jobs in nuclear, logistics, construction, and offshore wind. It is already booked in for its first project to start around the turn of the year.
A key feature of the crane, differentiating it from others of its size and type, is that it is all powered electrically and carries no hydraulics. Adding to its “green” credentials is the ability to feed electricity back into the grid. During a lowering operation electricity is generated by using the hoist motors as dynamos. This can then be fed back into the mains electricity network, reducing consumption by as much as 40 percent, Sarens said.
Without diesel generators or hydraulic power packs the crane is also much quieter, produces no exhaust fumes and there is no risk of contamination from hydraulic oil leaks. Less maintenance is a further benefit of a crane without engines or hydraulics which need fluid or filter changes.
The diameter of the ring is 35 metres and the maximum containerised counterweight is 3,000 tonnes. Main boom lengths are 100, 120, and 130 metres and jibs can be added, including a 27.5 metre runner and ones shared with other SGC series cranes. Erection or dismantling can be done in about four or five weeks, Sarens said.
