我们知道群吊电动葫芦也就是DHP型环链电动葫芦，主要通过起重链条来达到升降重物的目的，群吊电动葫芦在工作时所有的重量都压在起重链条身上，为了人员安全和起重作业的顺利进行。所以对起重链条的性能方面有着更高的要求。 We know that group of hanging type electric hoist is DHP were studied.the optimum processing chain electric hoist, mainly through lifting chain to achieve the purpose of lifting heavy objects, group of crane electric hoist at work all the weight of the pressure on the lifting chain, in order to personnel safety and lifting operation smoothly. So has higher requirements on the performance of the lifting chain. 　　群吊电动葫芦起重链条应坚固耐用、破断拉力大、表面光滑没有锈蚀、而且链条粗细相同等，起重链条应采用Φ7.1mm及Φ11.2mm 80级表面镍硬化起重链，起重链强硬化表面可以防止产品破损及核心材料的软化，使链条保持更好的性能，而且可以抗雨水海水等化学物引起的锈蚀。 Group of crane electric hoist lifting chain should be durable, breaking force big thickness, smooth surface, no rust, and chain etc., the same lifting chain should be 7.1 mm and 11.2 mm Φ Φ level 80 nickel surface hardening lifting chain, lifting chain hardening surface can prevent product damage and softening of the core material, to keep the chain better performance, but also can resist corrosion caused the rain water and other chemicals. 　　起重链条的材质一般为低碳合金钢，这种材质可以使链条更有韧性，而且耐磨性也好，另外，群吊电动葫芦的链条还可以根据客户需求来加长订做，让您更加省心方便。如果您需要我们产品，欢迎来电联系我们订购！ Lifting chain material is low carbon alloy steel commonly, this kind of material can make the chain more resilient, and wear resistance, in addition, the group of crane electric hoist chain can also be extended to build according to customer's requirements, make you more convenient save worry.
