The RTGs will incorporate an optional variable speed generator, which enables fuel consumption savings of up to 45%.
Kalmar will deliver seven E-One2 rubber-tyred gantry cranes (RTGs) to Puerto Central SA (PCE) in San Antonio, Chile.
The RTG project has a total value of USD14 million, including the cranes, spare parts, training for operators and technicians as well as civil works and other auxiliary equipment required to automate certain RTG processes.
The RTGs will enable Phase 1 of the terminal's capacity expansion of 450,000 TEUs as part of PCE's plan to become one of the largest container terminals in Chile. Besides a fast delivery time, it was vital for PCE to have the cranes delivered as fully erect.
"Kalmar RTGs are a well-proven product that allows us to ensure the success of our project in the short and long term," says Mauricio Argandona, infrastructure and equipment manager of PCE. "In addition, the deal will allow us to focus on other areas of our project, like civil works and subsidiaries' contracts."
Kalmar says the diesel-electric E-One2 RTGs will incorporate an optional variable speed generator, which enables fuel consumption savings of up to 45% by automatically optimising the engine's RPM to meet power requirements. The technology "can reduce CO2 emissions by 100,000 kg a year compared to a conventional RTG, based on a fuel consumption level of 21 l per hour and 4,000 operating hours a year". The Kalmar E-One2 RTG's maintenance interval of 1,000 hours is claimed to be the industry's longest.
Kalmar's SmartFleet, SmartStack and SmartRail systems are also part of the order, along with a full training package for RTG operators and technicians. Kalmar SmartFleet is a process automation solution that improves operational transparency in the port, while SmartStack eliminates the problem of lost containers. Kalmar SmartRail is an automated gantry steering solution for RTGs to improve safety and operator performance.
Delivery of the machines is scheduled for July 2015.
