www.kiswire.com The LeBus System is the only system on the market that can eliminate the 360o continuous cross winding of the cable as found on smooth drums. The LeBus System cuts down the cross winding to approximately 20% of the circumference of the drum while 80% of the wraps are parallel with the flanges. In view of this pattern, each layer of wire rope then becomes the groove pattern for each succeeding layer. Many benefits are derived from this system. One is safety. The LeBus pattern puts the same number of coils on each layer thereby eliminating the “cutting-in” of the cable. This severe scrubbing action can cause the wire rope to fail prematurely. The LeBus System is the only known method that can accomplish this feat. Therefore it creates a much safer environment. Another benefit is increased wire rope life. Since the wire is not “cutting in” and scrubbing on itself, the true pyramid stacking pattern promotes long rope life. Next are faster operations. By eliminating manual spooling or mechanical devices, a drum with LeBus grooving can be operated at higher speeds. Flexibility is an asset that cannot be overlooked. The sleeve can be added to the smooth drum either during original manufacturing or after the hoist is in the field. Wire rope savings - Wire Rope is expensive. Anything that promotes the increased life of the rope can be a huge cost saving. In order for the LeBus system to operate properly, certain parameters must be met. First, the drum flanges must be perpendicular to the drum barrel at all times, even under loaded conditions. Second, there must be sufficient tension on the wire rope to hold the wire firmly in the groove and keep it from skipping grooves or “back tracking”. Third, the fleet angle must be kept between ¼° and 1 ¼° (If the parameters are such that this cannot be held, then a LeBus Fleet Angle Compensator can be used). This insures that the rope enters the grooving pattern at the most optimum angle for spooling. Fourth, the rope must go to a fixed point that is centered with the drum width. Last, the rope must retain its consistent and round shape even under maximum loading conditions. Given these conditions, a LeBus grooved sleeve should spool KISWIRE ropes in multi- ple layers without any problems. Technical Data Sheet 8
