施工过程该如何使用链条索具 How does the construction process use the chain line 链条索具是在起重工程中使用比较频繁的五金索具，对起重工程有着重要的意义，同时其安全性也决定了起重工程的安全性，因此正确使用链条索具至关重要。 Chain rigging is used more frequently in lifting engineering hardware rigging, the lifting project has an important meaning, its safety also determines the safety of the lifting project, so the correct use of chain rigging is crucial. 1、对重大的起重、吊装项目，必须要制定施工方案和安全措施，经交底后方准施工。 For major lifting and lifting projects, the construction plan and safety measures shall be formulated, and the construction shall be carried out at the rear of the crossing. 2、起重量达到起重机械额定负荷，两台以上起重机械抬吊同一物件，起吊精密的、不易吊装的大件，在复杂场所进行大件吊装，起重机在高压输电线路下方或附近工作，都必须要办理安全施工工作证。 2, lifting weight lifting machinery reached the rated load, over two hoisting machinery carried down to the same object, precision, too big to not easy lifting operation, carried out at a complex heavy lifting, crane under high voltage transmission lines or near work, must deal with employee's safety construction. 3、起重机械应备有灭火器材，操作室内应铺设绝缘胶垫，严禁积存易燃物。 The hoisting machine should be equipped with fire extinguishing equipment, and the inside of the operation room shall be covered with insulating rubber mat, and the accumulation of inflammable materials shall be strictly prohibited. 4、塔吊等高架起重机，应该有可靠的避雷装置。 Tower cranes and other elevated cranes should have reliable lightning protection devices. 5、起重机工作应该有统一的指挥和信号，指挥应使用旗和口哨进行，不宜单独使用对讲机指挥联络。指挥人员应由有经验的起重工担任。 The crane should have a unified command and signal. The conductor should use the flag and whistle. The conductor shall be held by the experienced heavy industry.
