起重吊索具的选购及安全使用
Selection and safe use of lifting slings
1.在选择吊索具规格时，必须把被起吊的负载的尺寸、重量、外形，以及准备采用的吊装方法等共同影响的使用方式系数列入计算考虑，给出极限工作力的要求，同时工作环境、负载种类必须加以考虑。必须选择既有足够能力，又能满足使用方式的恰当长度的吊索具，假如多个吊索具被同时使用起吊负载，必须选用同样类型吊索具；扁平吊索具的原料不能受到环境或负载影响。
1. When selecting the lifting sling specification, the size, weight, shape of the load to be lifted, as well as the coefficient of the lifting method to be used and other factors affecting the service mode must be included in the calculation, and the requirements for the ultimate working force must be given, while the working environment and load type must be taken into consideration. The slings with sufficient capacity and suitable length to meet the use mode must be selected. If multiple slings are used to lift the load at the same time, the same type of slings must be selected; The raw materials of the flat sling shall not be affected by the environment or load.
无论附件或吊环是否需要，必须慎重考虑吊索具的末段和辅助附件及起重设备相匹配。具体参数可参照青岛鑫源诚贸易公司代理的卢森堡CODIPRO万向旋转吊环，其样册介绍了各种规格的旋转吊环直径、载荷、螺纹长度等，包括公制和英制吊环，而且安全系数高达5倍，比较适合高吨位的模具起吊。
Whether accessories or lifting rings are required or not, the matching between the end of the sling and auxiliary accessories and lifting equipment must be carefully considered. For the specific parameters, please refer to the Luxembourg CODIPRO universal swivel hoist ring, which is the agent of Qingdao Xinyuancheng Trading Company. Its sample book introduces the diameter, load, thread length, etc. of the swivel hoist ring of various specifications, including the metric and imperial hoist rings, and the safety factor is up to 5 times, which is more suitable for the lifting of high-tonnage molds.
2.吊索具安全使用严禁超负荷使用。无标记的吊索具未经确认，不得使用。吊索具组合部件上的部件按组合部件要求定期检查。不得采用锤击的方法纠正已扭曲的吊具。吊索具禁止抛掷。不要从重物下面拉拽或让重物在吊索具上滚动。
2. It is strictly prohibited to overload the lifting slings for safe use. Unmarked slings and riggings shall not be used without confirmation. The components on the assembly parts of the sling shall be inspected regularly according to the requirements of the assembly parts. It is not allowed to correct the twisted sling by hammering. Do not throw slings. Do not pull from under the load or let the load roll on the sling.
3.外购置的吊索具，必须是专业厂家按国家标准规定生产、检验、具有合格证和维护、保养说明书的产品。在产品明显处，必须有不易磨损的额定起重量、生产编号、制造日期、生产厂名等标志。
3. The slings and riggings purchased from outside must be products produced, inspected, and provided with certificate of conformity and maintenance and maintenance instructions by professional manufacturers according to national standards. At the obvious place of the product, there must be signs such as rated lifting capacity, production number, manufacturing date, manufacturer name, etc. that are not easy to wear.
