19 Extrusion Asia Edition 2/2019 SICA S.p.A. Via Stroppata 28 - 48011 Alfonsine - Ra - Italy www.sica-italy.com of hauling pipes up to 3.5 m /(138 in.) diameter, represents the new technical reference in the downstream machinery world for extremely large HDPE pipe extrusion lines. Despite being ab- le to achieve maximum pulling force equal to 900.000 N ( ≈ 200.890 lbf) using all its 24 caterpillars, it still guarantees reduced energy consumption thanks to the adoption of high- performance mechanical transmis- sions and requires minimum level of maintenance. To confront the oily behavior of po- lyolefins, all rubber pads of the ca- terpillars are made with new and special compounds. Their specific anti-wear properties combined with high contact friction, allow highly effective gripping action and a surprising increase in the average life of the pads. To avoid malfunctioning on these extraordinary dimensions lines, the new haul-off has been equip- ped with cutting edge manage- ment software and specific devic- es that constantly check the effi- ciency state of the machine dur- ing the pulling phase. Examples of these devices are: redundant encoders for precise speed moni- toring, and digital pressure sen- sors for continuous monitoring of working pressures and caterpillar tensioning force. Moreover, the independent control of each ca- terpillar makes this machine ex- tremely versatile despite its con- siderable size and allowing a par- ticularly wide range of process- able diameters (from DN2000 to DN3500). Robust pipe supports with electric handling both on en- try in and exit from the haul-off complete the standard equip- ment, making the management of the pipes simplified and safe, despite the sizes and extreme weights. Ultimately, SICA's proposal for haul-offs for HDPE lines is com- plete, and combines maximum performance and minimum ener- gy consumption, ease of use and process versatility, operational safety and environmental aware- ness, all of which are indispens- able today. 品质见于点滴 基于对技术的不断追求，SIKORA 团队推出了前瞻性的在线和离线检 测、分析及分拣系统，用于塑料颗 粒的在线和离线质量保障， PURITY SCANNER ADVANCED 是其中一 款产品。 – 在线检测并自动剔除含有杂质 的颗粒 – 可对颗粒表面及内部小至 50μm 的金属、有机污染物以及交叉污 染颗粒杂质进行检测 – 专业的数据分析管理（PDAM）系 统，可提供统计学数据、可视化 趋势图并记录数据 www.sikora.net/purityscanner 展位号： 10 H21
