Emmanuel Mair of Container Management looks at the way spreader manufacturers are moving firmly towards the direction of tandem lift operations helping customers reduce downtime and improve productivity.
Equipment companies normally have two basic things in mind when tailoring their products to customers’ needs: maximising the efficiency and productivity of their product offerings and ensuring that downtime is minimised through durable designs and quality maintenance. Spreader manufacturers are no different from anyone else in this respect.
The trend towards single-hoist tandem headblock systems is one which RAM Spreaders wants to capitalise on. Virtually all cranes delivered within 5–10 years will be single-hoist tandem, Cameron Hay, the company’s chief sales officer, told CM, citing studies by Shanghai Zhenhua Heavy Industries Co (ZPMC) and Shanghai International Port Group (SIPG), which suggest that dual-hoist systems are becoming antiquated.
RAM’s product can fit any standard headblock connection, while the changeover from a single spreader to a tandem spreader is fully automated, taking less than two minutes.
For terminals looking to operate in tandem, a key issue is the percentage of lifts that can be done in tandem. Hay explained: “Our clients have 40% tandem operations – that’s critical. One of the key reasons why they can do that is …click here to read the full article.
TOC Europe 2018 in Rotterdam played host to a talk by Cameron Hay on the trends in tandem lifting that show an increase in ports and terminals using single hoist tandem.
The talk began by making reference to published technical article by SIPG revealing some design and complexity issues with dual hoist operations and that dual hoist operations consume a high amount of energy, which as a result are not generally in high use. Also discussed was the fact that new terminals are not selecting dual hoist cranes, but instead opting for more economical single hoist dual spreader cranes.
The results of an independent review showed the RAM SingFlex single hoist system was a superior headblock.
“The industry is clearly moving toward higher TEU ratios and tandem 40 will be the norm. Terminals using SingFlex are achieving greater than 40% of all moves in tandem with its flexible design.”

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.

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

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
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.

Trends in using the RAM SingFlex Tandem 40 Headblock has been reported in the industry publication World Port Development.
In June 2016 World Port Development reported on the trends in multiple lifting.
The report looks into the new concept of lifting multiple containers using a single hoist crane, focusing on the successes of the RAM’s SingFlex Tandem 40 Headblock which is now in operation in China, South East Asia and North Africa and South America.
Also presented in the article is how SingFlex is flexible in operation, the energy saving benefits and explains the advantages over dual hoist systems.
