The LEBUS split-sleeve system consists of a pair of outer shells that are bolted or welded onto a smooth drum to provide a grooving pattern. Either helical or LEBUS parallel grooves can be carved into the sleeves.
As with all LEBUS drums, the grooving in split sleeves is engineered to match the specific rope construction, diameter and length, and to suit the application.
When the split type drum fence skin is installed, the split fence skin sleeve is wrapped on the smooth slotless drum, and is closely connected with the drum through bolts or welding, so that the original smooth surface of the drum outside the surface becomes the form of lebus double folding rope groove, which is convenient for the application of winch modification or replacement of the drum.
