The hall where the rotting compost is kept is 443 feet long and 197 feet wide, which roughly corresponds to the size of the layer-rearranging unit. The unit works at speeds of 0.3 ft/s.
Although the roller cable carriers have been in operation for over two years, so far they show no sign of wear whatsoever. The cable carrier systems are tested every month, after which a test report is generated. These reports confirm that no abrasive wear has taken place to date.
The roller cable carriers do not need lubrication and are not hindered by the weight of the encased cables, water and hydraulic hoses, or the slimy organic waste involved in this application.
Besides cable carriers, chainflex® continuous-flex cables, guide troughs, separators and strain reliefs from igus® are also used. The cables had to be laid in such a way that the load distribution was maintained throughout the length of the cable carrier. Separators keep cables and hoses apart.
