Cargotec introduces a new rubber tyred gantry (RTG) crane, Kalmar SmartPower RTG, which minimises fuel consumption and provides an excellent 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 litres per operational hour in typical RTG applications, which is the lowest fuel consumption without energy storage in the industry.
RTG Product Manager Marko Rasinen: "In a typical RTG operation between 9 and 18 containers are handled per hour. This is a very good fit for the SmartPower RTG, which provides the perfect 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 new innovative 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 the industry leading safety levels already featured in the Kalmar E-One2 RTGs.
The whole Kalmar E-One2 product family including the Zero Emission RTG with electric power supply helps customers to meet the latest environmental demands without sacrificing operational productivity and lifetime cost efficiency. The E-One2's maintenance interval of 1.000 hours, for both crane and optionally for engine, remains by far the longest in the industry and considerably increases terminal operational efficiency.
