Analysis of Wire rope hoist type definition

The so-called special Wire rope hoist is to accomplish a specific task and the development of dedicated Wire rope hoist . Its institutions, it refers to an institution within a year and the total number of running hours of the ratio. Changes in load level, according to the nominal amount of Wire rope hoist Wire rope hoist designed in the actual operation, the  lift hoist  loads are often less than the rated hoist capacity. According to hoist how busy work load and the degree of change, usually Wire rope hoist type of work is divided into: light, intermediate, heavy and extra heavy duty grade four levels. If the light level of the type of work that is used in heavy duty Wire rope hoist type of work places, Wire rope hoist will often fail, affecting safety in production. Therefore, security checks, pay attention to the type of work Wire rope hoist and working conditions must be consistent. By the Wire rope hoist structure carrying capacity, boom hoist capacity and overall stability against overturning three curves envelope.   rope hoist  type and amount of work are two different concepts,Wire rope hoist capacity, necessarily heavy grade, Wire rope hoist a small amount of light is not necessarily level. Wire rope hoist type of work and safety performance has a very close relationship. The amount of Wire rope hoist, span, lifting hoist the same height, if different types of work in design and manufacture, the safety factor is not taken by the same, that is, components, dimensions, specifications are different.
