JAPAN: On the test pad at Kobelco in Japan is a new lattice crawler crane with a maximum load moment rating of 6,000 tonne-metres. The 550 tonne (606 ton) capacity SL6000 is designed for world markets and will be especially targeted at applications that include construction of power stations and petrochemical plants, ports, shipbuilding and wind turbine erection.
It is the second new model (first was the CKE4000) in Kobelco's program of redesigning, upgrading and improving its 275 to 880 ton capacity range of models. As part of this program, the SL6000 is of modular design for easy transport, assembly and dismantling. According to a Kobelco source the machine will “look very European” and compete in the 600 ton class. The “SL” in the name stands for “Super Lifter” and the SL6000 will have Heavy Lift (derrick boom) and Super Heavy Lift (separate counterweight tray) configurations, with or without luffing jib.
