Lebus International Engineers GmbH was established by Karl Seidenather in 1962. It is a sister company of Lebus International Inc. of the USA and also has sister companies in the UK and Japan.
Lebus International manufactures drums and rope spooling systems for a wide range of onshore and offshore winching applications.
- Rope drums with grooves cut directly into them (with or without bolted or welded flanges, as required)
- Grooved split sleeves that can be placed over smooth, ungrooved drums – good for retrofitting and for applications where drums may require replacing in future.
- Spooling accessories such as spooling angle compensator and cross thread spindles.

The LEBUS® system:
In 1937 Frank LeBus, a supplier of equipment to oilfields, patented the use of a groove bar on hoisting drums to guide the spooling of rope.
In the 1950s he refined the grooving geometry and came up with the LEBUS® Counterbalanced Spooling System, which is still the most effective way to ensure that wire rope wrapped around a hoist drum in multiple layers continues to spool totally smoothly, and in a way that maximises the life of the rope.
Today, the term ‘Lebus’ is often used incorrectly to refer to any drum with parallel grooves. In fact, only a drum or sleeve produced by LEBUS® can truly claim to be a LEBUS® drum.
LEBUS® Split Sleeve System
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.
LEBUS® Winch Drum
Complete drum with flanges, machine-finished.
•The groove is cut directly into the body of the drum.
•According to customers’ requirements, the flanges are either welded or screw-bolted.
•The groove is available as either LEBUS®-groove or helical-groove.
•Groove geometry is determined by rope construction, diameter and length, and by application.
•The drum is provided with the requested mounting dimensions to fit the flanges by welding or screw bolting.
LEBUS® Diamond Screw Levelwinder
The clever mechanical spooling device for safe guidance.
With the LEBUS® diamond screw levelwinder fitted in conjunction with the LEBUS® special parallel grooving on the winch drum, there is the added advantage. It is adjusted by means of simple standard sprocket-chain connection to give the correct ratio between coils of rope on drum to pitches on the lead screw. Perfectly controlled spooling is guaranteed regardless of the number of layers on the drum.
