高性能无接头绳圈索具
出自:河北巨力吊索具销售有限公司 发表于:2017-08-31 作者:巨力索具

与普通无接头绳圈相比,该类绳圈在同等直径下,承载吨位更大,并在吊点部位作特殊处理,可延长索具使用寿命。

表中高性能无接头绳圈子绳采用 a 类、ab 类、钢芯、钢丝绳公称抗拉强度 1770MPa 系列钢丝绳制作,根据使用场合不同钢丝绳表面状态可为镀锌有油、镀锌无油和光面三种。

高性能无接头绳圈索具所用子绳规格不同,其破断载荷不同,可根据客户需求的钢丝绳结构来计算索具的破断载荷。

高性能无接头绳圈索具的最小破断力是额定载荷的 5 倍。根据行业要求的不同也可采用其它安全系数,当承载重量被精确计算或测定,提升操作被监控和操纵,动态系数被限定时安全系数可按《钢丝绳吊索 环索》GB/T30587-2014 执行,即绳圈直径≤ 60mm 时安全系数取 5,绳圈直径 Φ60 ~ Φ150mm 时安全系数(6.33-0.022D),绳圈直径大于 Φ150mm 时安全系数不得小于 3。

表中角度为对角腿之间的角度。

采用更高抗拉强度等级的子绳制作时,绳圈直径可作相应减小。
