高性能無接頭繩圈索具
出自:河北巨力吊索具銷售有限公司 發(fā)表于:2017-08-31 作者:巨力索具

與普通無接頭繩圈相比,該類繩圈在同等直徑下,承載噸位更大,并在吊點(diǎn)部位作特殊處理,可延長索具使用壽命。

表中高性能無接頭繩圈子繩采用 a 類、ab 類、鋼芯、鋼絲繩公稱抗拉強(qiáng)度 1770MPa 系列鋼絲繩制作,根據(jù)使用場合不同鋼絲繩表面狀態(tài)可為鍍鋅有油、鍍鋅無油和光面三種。

高性能無接頭繩圈索具所用子繩規(guī)格不同,其破斷載荷不同,可根據(jù)客戶需求的鋼絲繩結(jié)構(gòu)來計(jì)算索具的破斷載荷。

高性能無接頭繩圈索具的最小破斷力是額定載荷的 5 倍。根據(jù)行業(yè)要求的不同也可采用其它安全系數(shù),當(dāng)承載重量被精確計(jì)算或測定,提升操作被監(jiān)控和操縱,動(dòng)態(tài)系數(shù)被限定時(shí)安全系數(shù)可按《鋼絲繩吊索 環(huán)索》GB/T30587-2014 執(zhí)行,即繩圈直徑≤ 60mm 時(shí)安全系數(shù)取 5,繩圈直徑 Φ60 ~ Φ150mm 時(shí)安全系數(shù)(6.33-0.022D),繩圈直徑大于 Φ150mm 時(shí)安全系數(shù)不得小于 3。

表中角度為對(duì)角腿之間的角度。

采用更高抗拉強(qiáng)度等級(jí)的子繩制作時(shí),繩圈直徑可作相應(yīng)減小。
