The High-speed Reeling Cables That Keep Port Freight On The Move

Today’s ports are getting bigger and busier. Tratos’ advanced technology cable products for ports are helping keep the world’s freight on the move.
TratosFlex Reeling Cables offer increased reliability, robustness, performance, speed and safety for ports. As a reeling cable manufacturer, Tratos is second to none.

Cranes are at the heart of every port, and a wide variety are needed to handle containers as they make their journeys ship-to-shore and onto road and rail.  

Tratos makes the cable that keeps port equipment manufacturers’ machines running reliably and efficiently.

Cable from Tratos can be found working in mobile harbour cranes. They include Automated RTG (ARTG) and Automated RMG (ARMG) System cranes, Ship-to-Shore Gantry Cranes, Rubber Tired Gantry Cranes, Rail Mounted Gantry Cranes and Straddle Carriers.

Together with supplying cable for container cranes and Rail-Mounted Gantry Cranes, Tratos also manufactures crane festoon cable, mining cables and NSHTOU drum reeling cable.

Its flexible reeling, festoon, basket and chain cables have been specifically developed for cranes and material handling equipment in ports. These cables have to be of the highest quality to survive some of the harshest working environments.

The company’s Tratosflex cables are specifically designed for moving applications. They can supply power, control and signalling functions, including fibre-optic cables and components operating high-speedp applications up to 300 mt/min. Tratos supplies some of the strongest cables on the market for the industry.

With an outer sheath of red-coloured polychloroprene, Tratosflex-ES3-OS® is equivalent to or better than 5GM3 (or 5GM5 if required) quality.

Kevlar reinforcement, optical fibre, anti torsional protection and tinned, flexible conductors distinguish the range with TRATOSGREEN offering reductions in both halogens and toxicity.

High Speed Applications

Tratosflex-ESDB cables have been successfully installed in some of the highest profile projects worldwide, including London Gateway, Jebel Ali Port in Dubai and the Busan Port terminal in Korea. Leading crane company, such as Konecranes and ZPMC have used Tratos cables. Tratos is a major global player in the design, manufacture and servicing of reeling cables for container handling equipment.


The Tratosflex-ESDB range features a unique internal cable with a modified design that keeps cable tensioned to accommodate high speed applications. This prevents twisting which could lead to breakage during high speed reeling. Thanks to its tough insulation and sheathed drum Tratosflex-ESDB reeling cables can operate in temperatures from -60ºC to +90ºC. 

Approved Quality

Tratosflex cable range is tested and approved by CESI, CSI, BSI, IQNet and AENOR quality systems.

All Tratos’ cables for port equipment play a vital part in delivering efficient logistics – reliably and safely. Tratos works with port crane manufacturers that include some of the world’s leading producers: Liebherr cranes, Konecrane, Cavotec and ZPMC, alongside Cavotec Cable and DP World Cable.

Automated container handling systems provide shipping lines with uninterrupted and predictable flows, which in turn, deliver freight accurately and on time. Tratos’ cable is depended on to meet targets.

Tratos’ port cables can be found in ports worldwide, including Brisbane, Australia; the UK’s London Gateway Development; Khalifa Port in the United Arab Emirates and Jebel Ali Free Zone in Dubai. Tratos’ cable is also at work at Tercat Port, Spain; Virginia, USA; Busan Port Terminal, Korea; Euromax, Holland; the UK’s Thames Port; Damietta, Egypt; Rizhao Port, Asia and Qingdao-Qianwan Container Terminal QQCT.

Konecranes is the first company in the world to offer ARTG systems on a large commercial scale for both greenfield and brownfield sites. Tratos, which won a Queen’s Award for Enterprise: Innovation this year (2019) with its ground-breaking Tratos JBA cable sheath, supplies cable to the broadest range of reeling applications, including Konecranes’.

Cranes that keep our world moving:


Konecranes ARMG systems are at work at some of the world’s leading automated container terminals.

These are designed for greenfield and brownfield RTG-based container terminals. The cranes are built around Konecranes’ market-leading 16-wheel RTG and its ability to tolerate rough yard surfaces. The system includes a complete package of truck guidance infrastructure, a Remote Operating Station with a specially developed GUI, and an IT system that interfaces with your Terminal Operating System (TOS).


Konecranes has more than 40 years of experience in the design, manufacture and delivery of Ship-to-Shore (STS) container cranes and it has delivered more than 120, in sizes ranging from Panamax to Super Post Panamax. 

These Ship-to-Shore cranes are equipped with Active Load Control technology, which improves the crane operator’s control over the positioning of the spreader and container on the truck chassis, in the cell or on the deck, speeding up quayside productivity.



The Konecranes Rubber Tired Gantry (RTG) crane is making container handling safer, more productive and more reliable. Its streel structure, Active Load Control (ALC) technology and smarter cabin makes this crane the most productive and reliable in the world.

The Konecranes Automated RTG (ARTG) system is available for both greenfield and brownfield container terminals.

These cranes offer a range of power options for RTGs as retrofits, including a new Hybrid Power Pack. It covers off diesel-electric or fully electric options.

There are no hydraulics in Konecranes RTGs – a great advantage that provides greater reliability, less downtime and lower maintenance and spare part costs, particularly for ports in the harshest coastal conditions.


Konecranes’ Rail Mounted Gantry (RMG) cranes are the result of decades of design experience and performance. They incorporate recent innovations and technologies proven in millions of on-the-job working hours. The result is high performance, reliability, accuracy, low operating costs and low energy consumption. The company will tailor RMGs for the specific operation. It will also supply different sizes and configurations including zero outreach and outreach from both sides. Its design options also offer both rotating and non-rotating trolleys that lift all container and trailer types. 


Konecranes’ Noell Straddle Carriers are highly manoeuvrable, offering speed and reliability. They do not need yard infrastructure and are available in different sizes, stacking containers 1-over-2 or 1-over-3. This makes them ideally suited for step-by-step enlargement of container terminals. They are also available as automated versions and powered by eco-efficient diesel engines.

Straddle Carriers allow terminal operators to reduce the number of container handling machine types and interfaces, since horizontal transport and stacking are done by one machine type.

Latest drive technologies, variable motor speeds and integrated power management reduce operating costs and increase eco-efficiency.

Tratos continues to work with the world’s ports and the equipment manufacturers who serve them to develop even faster, even more reliable high-performance cable.

CASE STUDY: Tratos at Euromax

Tratos is celebrating more than a decade of continuous running of its reeling cable at  EuromaxTratos’ ground-breaking high-speed medium-voltage reeling cables in Rotterdam, Netherlands, is celebrating 10 years continuous running. The average lifetime of equivalent products on the market at the time of its launch was five years. During that time Tratos installed 36 cables, some of which replaced 22 competitor cables across 58 cranes at Euromax.The cables were installed in what was, at the time, one of the fastest automated rail-mounted gantry cranes (ARMGs) in the world, with containers transported from stack to truck at speeds of up to 270m/min.

Today several other terminals enjoy comparable speed and reeling cable is getting faster – with speeds now up to 300m per minute. Tratos remains at the head of the race, delivering cables to APM Terminal Virginia with speed up to 300m/min
Tratos’ high-performance cables are now installed in more than 300 ports around the world.
Tratos also supplies the cables for the port’s STS cranes.
