1. Capstan: Adopted the cast steel with tungsten carbide sprayed (or wearing resistance alloy), hardness HRC> 60, good wear resistance. With air cooling and narrow tube water cooling for choose. Reasonable taper designed to ensure that steel wire is not breaking and chaos 2. Driven system: The LZ350-LZ560 series machine are adopted the one-level or two level narrow V-belt with steady driving function. The LZ450-1270 series machine are adopted the first-level narrow V-belt + first-level hardened gear (Spiral bevel gear with a deviation correction device) for driving with good function of high engagement factor, smooth transmission, low noise, it also can be driving by first-level narrow V-belt + standard hardened gear box for driving
