Column cranes 5 ton @ 0,9 - 5,1 m

Recently, TMS supplied and commissioned two column cranes on board of two cutter suction dredgers successfully.
These robust cranes are executed with a driven slewing ring bearing and a driven trolley by a tooth rack on the bottom side of the boom. Hereby, the position of the vessel doesn't make a different for operating the crane.
TMS supplied dozens of cranes of this type, varying in load moment, on board of cutter suction dredgers in the last couple of years. The crane proved that it could move loads horizontally easily.
