Bulk handling crane with tough energy chain and cables
For the main power and data supplies, a motorised cable drum was initially used, involving slip rings that required a great deal of maintenance. For this reason, the crane operator decided to resolve the supply issue with a roller energy chain and dependable chainflex® cables with a 36-month warranty from igus®. This arrangement is not only simpler, safer and more secure than the motorised cable drum previously used, it also facilitates the supply of data via fibre optic cables. An igus® e-chain® and chainflex® cables have been in successful use since then with a travel of 441 metres and a max. acceleration of 01 m/sec².
