A 提升機(jī)的雙鏈長(zhǎng)鏈必須配對(duì)使用,由于刮卡等局部過載造成鏈條長(zhǎng)度超過配對(duì)公差時(shí),必須及時(shí)成對(duì)修復(fù)或更換。
B 圓環(huán)鏈允許的磨損值不得超過鏈條直徑的10%,超過時(shí),必須報(bào)廢;
C 應(yīng)經(jīng)常檢查鏈條的伸長(zhǎng),當(dāng)伸長(zhǎng)量超過標(biāo)準(zhǔn)長(zhǎng)度的5%時(shí),必須報(bào)廢;
D 鏈環(huán)出現(xiàn)裂紋、彎曲、扭曲或表面損傷現(xiàn)象和環(huán)間有卡死或僵澀滯阻等現(xiàn)象且不能排除時(shí),禁止使用;
E 個(gè)別環(huán)節(jié)距伸長(zhǎng)4-6%或個(gè)別部位出現(xiàn)明顯磨損,應(yīng)及時(shí)修復(fù)或更換;
