At cable winding today one uses one portal, one caterpillar, one spooling boom and one tower and the same kind of set of equipment for unwinding. This kind of solution is both expensive and unpractical when one of the components of unwinding/winding is stationary for a long time without being used. To save unnecessary expenditure and maintenance it would have been practical to only use one set of caterpillar, tower, spooling boom and portal that later on can be rotated around the turntable when exporting the cable. The project that this work includes is to bring a concept that excludes two sets and thus provides the system with a rotatable spooling system. To get as much information about the product and of the manufacturing as possible several interviews has been done of the forging shop Ronneby Svets & Smide and also their fitters. At the concept generation several proposals was developed and to go further with only one of them a QFD and a SWOT analysis was made to get the best concept. Verification of solid mechanics on the construction with FEM-analysis has been implemented on beams, tubes and tube constructions. The project comprises constructing of details and drawings for structure of the concept and also commitment of assembly, maintenance, ergonomics and shipping. At the assembly has bolted joints been used on most attachments for fast assembling on site instead of welds. For commitment of maintenance it is thought that one should easily access for control and tighten afterwards of example the slewing ring. At the ergonomics the idea is put for example to accessing the workspace or maintenance areas in form of a ladder or a staircase. The shipping has played a major role for the construction parts and has then been divided for easiest and most practical way to be transported smoothly.
