怎样安全使用起重机械？ | 2012-5-3 14:16:00

怎样安全使用起重机械？

    （1）司机和操作人员要经过专业的培训，并经有关部门颁发合格证后才能上岗作业，做到专机专人。指挥人员在作业前要熟悉所指挥机车的性能和了解所吊构件重量、现场周围环境。
    （2）操作人员对起吊的构件重量不明时要进行核实，不能盲目起吊。起吊连接在固定物上的物件，或埋在地下不明重量的构件，及与地面冻结的构件，必须采取技术措施后再起吊。
    （3）起重机在输电线路近旁作业，要采取安全保护措施。起重机与架空输电线的安全距离应不小于规定。
    （4）起重机操作人员在操作时，精神要集中，要服从指挥人员的指挥。在发现有信号不清或错误时，可以拒绝执行，要问清后再执行操作。在一般情况下起重机司机设二个人，一个人在机上进行操作，一个在机车周围进行监护。在作构件安装时可设高空和地面两个指挥人员。
    （5）起重机使用的钢丝绳，其结构形式、规格、强度要符合该机型的要求，卷筒的钢丝绳要连接牢固，排列整齐。当钢丝绳全部放出时，卷筒上至少要留三圈以上。
    （6）起重机在吊重自由下降时，因重力的作用对起重机产生大的冲击力，会造成机车的失稳倾翻，所以在非重力下降式起重机中，不能带载自由下降。但也有些进口起重机中在采取降低额定负荷量等措施后可使用自由降落。
