Kobelco unveils new crawler crane models
Coming up at Conexpo 2011 in Las Vegas
KOBELCO CRANES unveils new crawler crane models with new engine emission standards. Production of the new models for markets in North America and Europe will commence from 22nd of March 2011.
Cranes with lifting capacities ranging from 60 to 250 metric tons for Europe and 85 to 275 U.S. tons for North America have been newly designed, upgraded and improved from the customer’s point of view with safety, reliability and efficient operations in mind.
Features based on general concept
The concept of the new models has been created from end user and real jobsite experiences, incorporating “transportation friendly”, “assembly friendly” and “operator friendly”. All are essential to fulfil owner’s satisfaction. In addition, Kobelco emphasizes one more key concept as a global leader of crawler cranes: “environment friendly”.
The features of Kobelco’s new models are consistent with these key concepts.
- New engines comply with latest emission standard
All new models are equipped with new engines compliant with EPA Interim Tier IV and EURO stage IIIB. Rated output of the new engines has been upgraded from the previous series and tuned up for the best fit in crane operations.
- Achieved maximum 30% less fuel consumption from previous models
We adopted a totally new energy-saving assist system on all new models called the “G MODE” system. G MODE is a generic name for the assist systems such as Auto Idle Stop System, Energy Saving Winch Control System and Engine Rpm Limitation System.
＜Auto Idiling Stop function＞
Engine automatically stops during idling time under certain conditions. Restart is possible by controlling the accelerator grip.
＜Energy saving winch function＞
The hoist winch can be turned at maximum speed without engine accelerating under no-load lifting.
＜Engine rpm limitation function＞
By reducing the range of engine rpm, we achieved the best performance in normal mode.
- Compact design changes transportation duty
By newly designing the structure of the machine, transportability has been greatly improved. A minimum 2.99 meter width and 45 metric ton or less weight of the main house saves additional work needed for transportation such as arranging an escort car or special permission.
- Operator support system & comfortable operator cabin
The new safety support device is an optional item. The counterweight amount detection device always tells the correct amount of the counterweight. The swing angle detection device prevents over-swinging. The ground level sensor prevents operations on uneven ground. Machine status is displayed on a new wide monitor in a newly designed operator cabin. The new luxurious cabin enhances comfortable operation.
- Vertical cylinders for counterweight self installation (80 tons to 110 tons)
The new models have an improved counterweight self installation mechanism. Counterweights can be stacked up on the ground and installed on the machine by vertical cylinders. Safety and work efficiency have been greatly improved.
- New hydraulic circuit; Dual pump flow Single pump flow
New models are adaptable to work at both bucket and lifting job applications. The hydraulic circuit can be fixed as dual pump flow or single pump flow, so that the circuit can be perfectly adequate for both applications. The new designed circuit can be switched to choose the best circuit for your job application.
