The new CK3300G-2 hydraulic crawler crane has a maximum lifting capacity of 330 US tons (300 metric tons) for standard crane and 385 US tons (350 metric tons) with a Super Heavy Lift (SHL) attachment. There are numerous CK3300G-2’s now working on various job sites in North America, but CONEXPO is the first time Kobelco will exhibit this new model in North America.
Mobile cranes are now being required to have higher lifting capacities, as well as improved productivity and safety. Kobelco’s response was to develop this “versatile” crane that can handle a wide variety of applications in different job sites by utilizing Kobelco’s s time-proven technologies in the production of multi-purpose cranes.
These cranes are well-suited to work in a full range of applications across a wide variety of industries, from pile driving to steel erection, tilt-wall work, industrial equipment installation, and other heavy lifting jobs.
Kobelco has built a “G” Series service training simulator that is being used to train service personnel from dealers to crane owners. The simulator is built to be shipped to the customer’s yard for schools onsite. Kobelco schools are free of charge because it is their belief that the more people who know the systems, the easier it is to minimize downtime. The G-Series simulator will on display at ConExpo.
The G-2 series cranes lifting capacities range from 80 to 330 U.S. tons for North America and 60 to 300 metric tons for Europe.
