The unloader is scheduled for delivery in December 2013 and will be transported to the installation site in pre-assembled sections.
The order is booked into Cargotec's third quarter 2012 order intake.
Cargotec received the order from global engineering, consulting and construction company Black & Veatch Corporation, which has its headquarters in Kansas, U.S.
The project will be implemented by the Black & Veatch regional office in Beijing.
"The client had an early preference for a continuous ship unloader, and for a screw-type unloader in particular," said Ola Jeppsson, Cargotec sales manager.
"This was because of its efficiency, reliability and environmentally-friendly operation. The system's slim footprint and low weight also mean that it offers savings in jetty construction costs."
