www.kiswire.com SPLIT SLEEVES It is not always necessary to purchase a new drum. Lebus can supply its grooving system on outer sleeves that can be bolted or welded onto your old drum, no matter how old or worn it is. Lebus split sleeves can also be an economic option for new drums. If in future a different type or size of wire rope is used, the sleeve can be taken off and replaced with a new sleeve engineered for the new application. The Lebus system is so flexible that it can be individually adapted to any existing or new hoist system, even in extreme operating conditions and high loadings. The Lebus system can be installed either during the manu- facturing process or later onsite. The cost benefit of the technology speaks for itself. ROPE DRUMS, SPLIT SLEEVES AND SPOOLING ACCESSORIES Rope drums - rope drums with grooves cut directly into them (with or without bolted or welded flanges, as required). Split sleeves - machine-grooved split sleeves, supplied in two sections that can be placed over smooth ungrooved drums. Split sleeves are a good solution for retrofitting and for applications where drums may require replacing in future GROOVED SLEEVES Sleeves are used to prevent damage to a drum. It is usually cheaper to replace a worn out sleeve instead of replacing or repairing the complete drum assembly. That is why grooved sleeves have become so popular. The LeBus Grooving System involves a product made specifically for use on any or all types of hoisting drums requiring the use of wire rope or electro-mechanical cable. The LeBus grooves are made for the purpose of properly seating a specified size of wire rope and the proper movement of and spacing of the cable from flange to flange. The material is supplied in cylindrical form, either from steel, fiberglass, or aluminum to fit over any existing or new drum core. Sizes range from 3 inches to over 18 feet in diameter and 4 to144 inches (or more) in width. The grooved cylinders are split in halves for easy installation either by welding or bolting to an existing drum core. After the installation has been accomplished, the grooves supplied by LeBus set a pattern whereby a repetitive action of layer to layer spooling can be controlled regardless of the number of layers or drum speed, size and load on the drum. The primary purpose of the LeBus Spooling System is to spool wire rope or cable onto hoisting drums in a true and correct manner. In most spooling operations, you never encounter severe spooling problems when spooling only one layer of cable on your drum. In all other cases, your trouble will begin when you start the second layer and from there on up through your last layer. Technical Data Sheet 8 reversing and fi riser X starting end filler DRUM FLANG
