Lebus drum 
spooling technology are recognised by engineers all around the world. Thanks to the geometry of the parallel groove on the drum, LEBUS® enables wire ropes to
be spooled in multiple layers with complete reliability and in a controlled manner. This results in a perfect spooling pattern. Preventing mis-spooling not only maximises system up-time, it also increases the service life of the wire rope, since it prevents the kind of pinching and crushing often seen in other spooling systems. And by guaranteeing the performance and safety of multi-layer spooling, the LEBUS® system facilitates the use of shorter drums, saving space for machinery installations, as well as saving weight and money. LEBUS® groove The LEBUS® groove can either be machined directly into the drumcore or, more usually, onto two shells – or sleeves – that are then bolted or welded onto the face of the drum. The benefit of our split sleeves system is that, because the groove geometry is tailored to the size and construction of the wire rope, if a new type of rope is needed, it is much easier, quicker and cheaper to simply change the LEBUS® sleeves rather than the whole drum. Lebus® split sleeves can be retrofitted on site in the remotest locations, even on offshore oil rigs and cranes.
