Kalmar is to deliver seven E-One2 rubber-tyred gantry cranes (RTGs) to Puerto Central (PCE) in San Antonio, Chile as part of a US$14m RTG project. The order includes the cranes, spare parts, training for operators and technicians, as well as civil works and other auxiliary equipment required to automate certain RTG processes.
To be delivered fully assembled and with a start-up date of July 2015, the new machines will enable Phase 1 of the terminal’s capacity expansion of 450,000 teu to begin. The project is part of PCE’s plan to become one of the largest container terminals in Chile.
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 according to the required power. This technology can reduce CO2 emissions by 100,000 kg a year compared to a conventional RTG, based on a fuel consumption level of 21 litres per hour and 4,000 operating hours a year. The Kalmar E-One2 RTG’s maintenance interval of 1,000 hours is the industry’s longest.
