液壓支架千斤頂使用要點

作者: 來源: 日期:2023-01-16 08:39:46 人氣:77 評論:0

  一、液壓支架千斤頂在頂升作業時,要選擇合適噸位的液壓千斤頂,承載能力不可超負荷,一般選擇液壓千斤頂的承載能力需大于重物重力的1.2倍;液壓千斤頂最低高度合適,為了便于取出,選用液壓千斤頂的高度應與重物底部施力處的凈空相適應,起落過程中墊枕木支持重物時,液壓千斤頂的起升高度要大于枕木厚度與枕木變形之和。    

  二、若使用多臺液壓支架千斤頂聯合頂升同一設備時,應選用同一型號的液壓千斤頂,且每臺液壓千斤頂的額定起重量之和不得小于所承擔設備重力的1.5倍。  

  三、液壓支架千斤頂在使用前應擦拭干凈,并應檢查各部件是否靈活,有無損傷和漏油現象。在有載荷時切忌將快速接頭卸下,以免發生事故及損壞部件。
