A recent independent report published by Ports & Waterway Engineering provides a valuable tool for ports evaluating different crane options.


Shanghai International Port Group (SIPG) a terminal operator at the world’s largest port of Shanghai which handles over 35 million TEU’s has undertaken a scientific evaluation of several tandem lifting systems.

They have found that dual hoist cranes breakdown significantly more, they cost more to maintain and use more energy per box and with a price tag greater than 1 million USD.  From this they have evaluated several single hoist tandem systems available on the maket.

“This article is a great tool to assist port engineer evaluating the pros and cons of tandem 40 systems for their projects” Cameron Hay – RAM Spreaders
