起重吊運(yùn)鋼絲繩的破斷拉力慨約計(jì)算公式解析

1、起重吊運(yùn) 鋼絲繩的破斷拉力慨約計(jì)算公式：鋼絲繩直徑（mm）的平方乘以50等于破斷拉力（公斤）此公式二十年前在一本 起重機(jī)方面的書上學(xué)的，工作中運(yùn)用較方便。 對照鋼絲繩表查，基本 上符合6乘19纖維芯鋼絲繩 公稱抗拉強(qiáng)度1670兆帕的鋼絲繩最小破斷拉力。起重吊運(yùn)用時(shí)應(yīng)將破斷拉力除以 安全系數(shù)6倍等于安全負(fù)荷。QQQQQQQQQQQQQQQQQQQQQQQQ一般礦井用鋼絲繩有以下種類：1、斜井提升用 6X7+FC 和 6TX7+FC（面接觸）、6X19S+FC 和 6TX19S+FC、6VX19+FC ；2、豎井卷揚(yáng)提升一般用 6X26WS+FC 6X36WS+FC 18X7+FC 6VX34+F
