Kobelco testing a 550 tonne crawler

15 April 2008

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 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 programme of redesigning, upgrading and improving the 250 to 800 tonne capacity range of models. As part of this programme the SL6000 is of modular design for easy transport, assembly and dismantling. According to a Kobelco source it will “look very European” and compete in the 600 tonne 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. Look out for more details on this new model as they become available in a future issue of IC.
