After two years Tratos cables continually working without any corkscrew effect in Euromax, the Rotterdam port. Speed 270 m/m. Let's take another turn!
Increasing tension: in the cable market
World Port Development - October 2008
Over the years, cable manufacturers have faced some tough times. First, it was adapting their cables to cope with higher traveling speeds. Then the price of copper was an issue and now the global economic situation might be a factor. Peter van Schie reports on how cable manufacturers keep rising to the challenge…
Ever increasing speeds of cargo handling equipment demands more from the cables used in the energy chain systems. Maurizio Bragagni, Managing Director at Tratos cavi SpA, talks to World Port Development. Today’s new generation of container cranes, including RTGs and RMGs, are designed with increased travelling speed up to hundreds of meters per minute and a new kind of cable is required to meet this challenge. Otherwise the consequences are too risky for both the operator and cable manufacturer...
Nowadays, nobody wants to spend time and money on intensive maintenance jobs for their cargo handling equipment. Once the equipment is commissioned it should be reliable and, if possible, maintenance-free. Therefore performance and lifespan of cables can´t be left to chance. Peter van Schie reports…...
Tratos Cavi SpA, the Arezzo, Italy-based cables manufacturer, has come up with a new cable design for high-speed long travel applications on RMGs. Experience tells us, says the company, that the most common problem is twisting. The faster the reeling speed, the greater the risk, as higher speeds result in increased tension and torsion and forces all the elements that make up the cable - power/earth cores, inner sheath, outer sheath and anti-torsional protection - to move against one another. The relative motion makes the cores elongate unevenly during bending and the conductors on the outer layer of a strand can easily be broken...
Tratos Cavi launches cable for high speed box cranes
Cargosystems.net - February 2009
Terminals operating new generation high-speed container cranes should invest in a new kind of cable to avoid the risk of costly damage, according to cable supplier Tratos Cavi. The company’s recently launched TratosFlex-ESDB cable has been designed to combat the common problem of twisting that affects cables reeling at high speed. Higher speed results in increased tension and torsion on cables and forces all cable elements – power/earth cores, inner sheath, outer sheath and anti-torsional protection– to move against one another...
