Cable management on cranes at seaports is becoming an increasingly important issue. With the extreme length of travel and speeds that these modern cranes are operating at (be it ship to shore, rail mounted gantry, or rubber tyred gantry cranes), the traditional cable management methods on port cranes are being pushed to their design limits. To address these concerns, Tsubaki KabelSchlepp developed the next evolution in cable carriers with the creation of the Roller Supported Chain (RSC) system. The RSC system has been specifically designed to solve cable management needs within the port crane industry. Traditional methods of cable management on port cranes has generally been handled with festoon systems or increasing more often with standard cable carriers.
The development of the RSC System resolves the shortcomings of the traditional cable management methods on port cranes. The RSC system does not use rollers built into the cable carrier, because having the wheels as part of the link construction can cause excessive vibration and jams that will lead to accelerated wear and eventually total replacement of the cable carrier. The RSC system was designed so that the upper run of the cable carrier never comes in contact with the lower run of the cable carrier like traditional cable carrier designs…
