Cargotec Introduces Gantry Crane

Cargotec has introduced a new rubber-tired gantry (RTG) crane, Kalmar SmartPower RTG, which minimizes fuel consumption and provides a balance between productivity and cost efficiency.
The new crane is equipped with an intelligent power management system and a significantly smaller diesel engine, compared to conventional RTGs. These technological innovations lead to a fuel consumption of only 9 liters per operational hour in typical RTG applications.
"In a typical RTG operation, between 9 and 18 containers are handled per hour,” said RTG Product Manager Marko Rasinen. “This is a very good fit for the SmartPower RTG, which provides balance between productivity and cost efficiency.''  
In the Kalmar SmartPower RTG, the new power management system ensures the most economical engine RPM is used at all times during operation and controls speeds and accelerations to reduce the peak power requirement. With Cargotec's approach, energy consumption and exhaust emissions are greatly reduced. The new Kalmar SmartPower RTG is based on Kalmar E-One2 all-electric design without any hydraulics, and it incorporates safety levels already featured in the Kalmar E-One2 RTGs.
