手拉葫蘆運用安全操作規程

    手拉葫蘆運用安全操作規程

    手拉葫蘆是一種以鏈條（通常用圓環鏈）作為它的起重柔性件的手動起重東西，其手拉鏈為環鏈。該產品特點是自重輕、體積小、轉移方便，能夠垂直提高重物，也能夠橫拉重物，運用範圍很廣。規範起分量為0.5—20t。

    傳動齒輪及承載鏈條、驅動鏈條應該常常留意保護、fangzhishengxiu，yijianxiaozuli。yunyongshibugailuanrengluanpao

    如果發現傳動齒輪有裂紋，斷齒或齒麵磨損在原齒厚的30%，齒輪應予作廢。鏈條產生塑性變形，其伸長量達原長的5%

，或許產生卡鏈現象，鏈環直徑磨損到原直徑10%應作廢。製動片不能達到要求的製動力矩
，吊鉤損壞抵達規定的作廢規範時均應替換。
