1、起吊重物时,吊钩钢丝绳应保持垂直,不准斜拖被吊物体。
2、所吊重物应找准重心,并捆扎牢固。有锐角的应用垫木垫好。
3、在重物未吊离地面前,起重机不得做回转运动。
4、提升或降下重物时,速度要均匀平稳,避免速度急剧变化,造成重物在空中摆动,发生危险。落下重物时,速度不宜过快,以免落地时摔坏重物。
5、起重机在吊重情况下,尽量避免起落臂杆。必须在吊重情况下起落臂杆时,起重量不得超过规定重量的50%。
6、起重机在吊重情况下回转时,应密切注意周围是否有障碍物,若有障碍物应设法避开或清除。
7、起重机臂杆下不得有人员停留,并尽量避免人员通过。
8、两台起重机在同一轨道上作业,两机间距离应大于
9、两台起重机合吊一物体时,起重量不得超过两台总起重量的75%,两台起重机走行、吊放动作要一致。
10、起重、变幅钢丝绳需每周检查一次,并作好记录,具体要求按起重钢丝绳有关规定执行。
11、空车走行或回转时,吊钩要离地面
12、风力超过六级时,应立即停止工作。TMK应将臂杆转至顺风方向并适当落低,将吊钩挂牢。龙门吊须打好铁楔(止轨器),并将吊钩升至上限。同时关好门窗,切断电源,拉好缆风绳。平时工作完毕后也应照此办理。
13、起重机平台上严禁堆放杂什物件,以防在运行中掉下伤人,经常用的工具应放在操作室内的专用工具箱内。
14、运行中,不准突然变速或开倒车,以免引起重物在空中摆动,也不准同时开动二项以上(包括副钩)的操作机构。
15、开车时,操作人员的手不得离开控制器,运行中突然发生故障时,应采取措施将重物安全降落,然后切断电源,进行修理。严禁在运行中检修保养。
16、起重机遇有下列情况之一者不得起吊:
1、重物超过起重机额定起重量。
2、重物重量不明。
3、信号不明。
4、重物捆扎不牢。
5、露天作业遇六级(梁上五级)以上大风及大雨、大雾等恶劣气候。
6、夜间作业照明不好。
7、斜拉。
8、钢丝绳严重磨损出现断股及有人在起重机上或机房进行检修。
