The cranes can simultaneously handle two 40 ft containers or four 20 ft containers, with a total laden weight of 80 tonnes. Their outreach is 67 m and they can handle 24 containers across, allowing them to serve the world’s widest container vessels in the foreseeable future (currently the widest vessels are 22 containers across). They also have a wide rail gauge of 35 m, allowing eight lanes for tractors and greater operational efficiency.
All 12 cranes are of the same model and have been purchased from Shanghai Zhenhua Port Machinery Co. Ltd (ZPMC). In line with the development of Da Chan Bay Terminal One, the first batch of eight cranes was delivered in 2007, two more were delivered in early October 2008 and the remaining two on October 15.
The full fleet of dual-hoist tandem-lift quay cranes is one of the showcase features of Da Chan Bay Terminal One. Andrew Milliken, the terminal’s CEO, said: “When we placed the order for these 12 cranes with ZPMC in 2006, we were determined to provide efficient operational service to the biggest vessels in the world. We have been using this model of crane since the terminal opened in December 2007 and feedback has been positive. We will purchase more dual-hoist tandem-lift quay cranes for future development of the terminal.”
