起重机配件是在各种项目工程、建筑等大型施工场地点的必备机械设备，起重机配件设备在作业时最受人们关注的就是安全问题，它的能够安全的工作，不仅仅需要操作人员在作业中规范的按照标准执行， 还需要起重机配件各部位的完好来配合。起重机配件是否完好无损对着整个工作过程中影响是非常大的。 起重配件所指的是啥呢？其实起重配件即是指起重机上的一些装备，有吊钩，还有吊钩组，有行程限位开关，有熔断器，有过电流继电器等等都是起重机械上的配件，这样说我们是不是理解呢？那么啥是熔断器呢？它都有哪些效果呢？
Crane accessories is in all kinds of project engineering, construction and other large construction site the necessary machinery and equipment, crane accessories equipment when working in the most attention is security problems, it can safely work, not only need to operating personnel in the job specification in accordance with the standards, also need to crane accessories intact to match each part. Crane accessories are in good condition on the whole working process of the influence is very big. Lifting accessories is referring to what? Lifting accessories that is actually refers to some equipment on the crane, a hook, hook group, there are lead limit switch, fuse, have over-current relay and so on are all on the hoisting machinery accessories, said that if we understand? So what is the fuse? What effect does it have?
Fuse (fuse) refers to when a current flows beyond the specified value, with its attack heat makes the melt fuse and disconnect the circuit of a kind of electrical appliances. Fuse is the over current maintenance. Fuse is mainly composed of the melt and the fusion tube and plus some packing, etc. When use, will fuse in series in the circuit under maintenance, when the current of the circuit under maintenance beyond the specified value, and through a certain hour, by melt their attack heat fusing melt, make the circuit disconnect, then to have the maintenance effect.
