Tratos is celebrating 10 years continuous running in Euromax

Tratos’ ground-breaking high-speed medium-voltage reeling cables at Euromax in Rotterdam, Netherlands, is celebrating 10 years of continuous running.  The average lifetime of equivalent products on the market at the time of its launch was five years.

During that time, as part of a framework contract, Tratos has installed 36 cables, some of which replace 22 competitor cables across the 58 cranes at Euromax.

In addition, Tratos also supplies the cables for the STS cranes.

The cables were installed in what was, at the time, one of the fastest automated rail-mounted gantry cranes (ARMGs) in the world, where containers are transported from the stack to the truck at a speed 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

In 2008, when first installed, there was almost no benchmark for the anticipated lifespan of cables running at such high speeds. Tratos installed TRATOSFLEX ESDB 6/10kV cable which is developed especially for the needs of this terminal.

Tratos’ continuous running high-speed reeling cable reliability has not only proved itself but raised the game for the market.  Several of the company’s TRATOSFLEX ESDB cables operate now with a decade’s performance under their belt and more performance and safety advances are on the horizon.

Many different factors influence cable lifespan, but TRATOSFLEX ESDB cable has continued to cope – and perform consistently in an unbroken run since its installation.

TRATOSFLEX ESDB was developed to resist high pulling tension and abrasion of the outer sheath – rubber-insulated copper cable can fail when these two materials are wrapped around each other.

During the cable’s life, its tough environment – the constant reeling application – is an ever-present challenge.  Cable is generally the weakest point of any crane and relies on regular maintenance to preserve its integrity.

At the time, Tratos’ task was to produce a super-tough outer-sheath and make the inner construction as strong as possible for client ZPMC, the largest heavy-duty equipment manufacturer in the world.

TRATOSFLEX ESDB was the result. Its modified cable structure tightens the components against internal movement to accommodate the stresses involved in high-speed applications. This prevents the most common problem of twisting, leading to possible breakage that affects cables reeling at high speeds.  High-quality compounds also ensure the cable operates in temperatures from -20ºC to +60ºC.

Tratos’ high-performance cables are now installed in more than 300 ports around the world.
