Container Handling: Cables and Reels

How's the weather?

Port operators need to take environmental conditions into account when choosing cables for their terminals, says Don Nester of igus.

“Cable carriers can replace alternative options such as festoons or reels, which leave cables vulnerable to damage from wind, rain, snow and other elements,” he says.

“Our Energy Chain cable carriers partnered with Chainflex continuous-flex cables provide operators with a complete motion control system. Igus also offers cables designed for the crane industry, as they are equipped with a pressure-extruded, flame-retardant, TPE-blend outer jacket – these jackets feature a wide temperature range for severe environments and are for long travel, outdoor applications.”

Among new developments from igus is the Push, Pull Detection System (PPDS) for its Energy Chain System cable carrier assemblies. This system computes push-pull forces by comparing force values relative with the position of one of these assemblies; an Energy Chain System comprises polymer cable carriers and Chainflex continuous-flex cables, and comes with options such as mounting brackets, drive plates and interior separators.

“The PPDS provides the customer with performance information about their system,” says Mr Nester. “It also prevents damage to equipment by providing early warning signals – the system will fully stop or slow down – enabling the operator to perform maintenance before components are damaged, and saves money by preventing downtime and frequent maintenance.”

Which cables will last the longest, be most effective and require least maintenance? The answer, says Mr Nester, is that cables equipped with a strong outer jacket – ideally TPE – have the ability to cope with a wide temperature range and constant motion and are the best choice for outdoor, crane applications.

Although festoons and reels are a common solution in ports, they can leave cables and hoses vulnerable to harsh outside elements such as rain, salt, wind and dirt, he adds.

“Corrosion-free, high-performance polymer cable carriers with hinged crossbars for easy cable access, or fully enclosed versions, are especially useful for keeping cables from harm.”
