we saw the need to improve the spooling of wire rope on the Drilling Rigs began trying different methods and eventually created the "LeBus" pattern which is still the best method used today for spooling multiple layers of wire rope evenly and accurately. With LeBus now supplying its products to all industries that need to spool multiple layers of rope, LeBus still remembers where it began and goes above and beyond to support the Oilfield with LeBus Grooving, and much more. To this day LeBus is still used on practically every Drilling Rig and Workover Rig in the world. .

The structural point of the LEBUS groove
The drum rope groove of drill winch adopts the form of double broken line structure, and its characteristics are diagonal rope groove and straight rope groove appear alternately, thus forming two diagonal rope groove area and two straight rope groove area on the surface of the drum. The so-called inclined rope groove refers to the rope groove that intersects diagonally with the drum bus, and the straight rope groove refers to the rope groove that intersects directly with the drum bus or is parallel to the flange. Diagonal strong groove controls the pitch of rope groove, which accounts for a small proportion in a circle of rope groove. Its structure point can effectively alleviate the problems of extrusion deformation, mutual friction and early wear of wire rope during loading.
The processing and production of the lebus groove can be directly processed on the drum as a whole, and can also be made into a set with the rope groove, and made into a split type, wrapped in the smooth drum when installed, connected with the drum through bolts or welding. The material of folding rope groove barrel can be divided into carbon steel, stainless steel, alloy steel, aluminum or glass fiber, etc. The barrel can be made by sheet rolling or casting.
Double drum winch
In order to meet the requirements of drilling technology and transportation, the winch is usually designed as a multi-shaft drive and separate transportation, which not only makes the system complex, but also increases the cost and installation workload. To this end, the transmission scheme of the winch, power input mode and the structure of the winch frame have done pioneering work, my company designed a multi drums winch. The winch is mainly composed of base, winch frame, roller shaft, sand drum shaft, shaft drive boxes, disc brake, crash-proof crown device, main brake mechanism and automatic driller, etc, and power shift between the input shaft and the shaft adopts mechanical transmission, drive shaft and roller shifting between adopts pneumatic clutch to shift, with four are blocked, reverse gear. Finite element software was used to simulate and analyze the drum shaft and check its strength and stiffness. The analysis and check results show that the design of the drum and frame of the winch is reasonable and meets the practical work requirements.
