Port of Qingdao automated terminal uses RAM SingFlex to help achieve 5.2 million TEU capacity

RITN Port of Qingdao

Port of Qingdao Automated Container Terminal is able to achieve 5.2 million TEU capacity thanks to the RAM SingFlex twin spreader headblock connection on single hoist cranes.

XINHAUNET news reported in May on the Port of Qingdao putting into operation their fully automated container terminal which has the ability to serve 24,000 container ships every year thanks to the RAM SingFlex tandem headblock connection; which enables the port to increased lifting rates with single hoist cranes.

We reported back in our April 2017 Newsletter on the Port of Qingdao ordering 7 units of our RAM SingFlex single hoist tandem 40 headblocks for their fully automated terminal.

The order followed the terminal’s long study into the RAM SingFlex tandem headblock connection for single hoist cranes with alternatives.  The study recommended the RAM SingFlex to be the solution for the two new automated terminals because of the flexibility, low capital cost and proven stable design.  It also has the flexibility to couple with all spreaders, ensuring no obsolete equipment.

RAM SingFlex is quickly becoming the tandem headblock of choice with units sold in China, Southeast Asia, North Africa, South America and UK.

World’s largest port has reviewed & evaluated different options for high productivity tandem cranes in a recent technical article


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

Container Management reports on the latest innovations

CM Spreader Article

Emmanuel Mair of Container Management looks at the latest innovations that spreader manufacturers are bringing to market and reports on the RAM SingFlex Twin Spreader Headblock Connection.

For terminal operators, the search for productivity gains can often seem never-ending.  Of course, for equipment manufacturers this presents both a challenge and an opportunity to entice customers with safe, reliable and high-performance equipment – including the spreader market.

RAM Spreaders is currently focusing on its RAM SingFlex tandem headblock for multiple container lifting, which is in use at several APM Terminals (APMT) and DP World facilities.  Many terminals are already familiar with the concept of lifting two 40ft containers simultaniously.  Single-hoist tandem capability allows terminals to work tandem operations for less than 3% of the capital cost of an extra ship-to-shore (STS) crane according to RAM.

Trends in Multiple Lifting

SingFlex Case Study Pic
With vessels getting larger ports are innovating to be able to transfer the containers from these massive behemoths faster.  When the 18000 TEU CMA Benjamin Franklin, with 9 decks 9 rows high and 23 wide calls at a port, a faster approach is needed.  The answer; many ports are turning to the RAM SingFlex tandem headblock for multiple container lifting.

Carrying two 40 foot containers is not a new concept, it has been happening in Dubai for a decade and after years of experience terminals are fine tuning how to do this. Experienced tandem crane operators, like DP World and APM Terminals, have learned that all cranes on a vessel do not need to work at the hectic pace of 60 containers per hour, instead focus needs to be on the larger points of work which control the vessel sailing. Flexibility is the key to turn around these vessels. You only need to work 2 or 3 cranes at 60 moves per hour.
