使用鋼絲繩手扳葫蘆的安全要求

文章出處:未知作者:admin人氣:發表時間:2016-05-11 15:10【

鋼絲繩手扳葫蘆的安全要求:
(1)使用手扳葫蘆時,起重量不準超過允許荷載,要按照標記的起重量使用。
(2)使用時不能任意的加長手柄,因手扳葫蘆的起重量是有限的,兩手扳力也有一定的大小,加長手柄會造成手扳葫蘆的超載使用,致使部件損壞。
(3)要經常檢查鋼絲繩有無磨損和扭結、斷絲、斷股,凡不符合安全使用的一定要更換。
(4)由于手扳葫蘆的工作原理是利用夾鉗交替夾緊鋼絲繩的,所以要求使用鋼芯的鋼絲繩而不能用麻芯鋼絲繩,因麻芯繩柔軟而富有彈性,在夾鉗夾緊后有易松動的現象,是不安全的。
(5)手扳葫蘆使用前要作全面的檢查與測驗,使用后要維護保養。
