Working-level description of the crane

The size of the crane working-level height is determined by the ability of two kinds, one is the frequency of the use of the steel crane , called crane utilization level; second is the size of the crane under load, called the crane load state.

1. Level of utilization of the crane
Cranes in the effective work during the lifetime of a certain total reincarnation. Crane's work reincarnation homework preparation for lifting objects from the start, lifting items up to the next whole homework process. Characterization total working cycle of the crane utilization, which is one of the basic parameters of the  hoist gantry crane  classification. Total is working cycle during the life of the crane in the demarcation of the sum of all the work cycle times.

Determine the appropriate useful life, to consider the economic, technical and environmental factors, but also involves the impact of aging equipment.

        2. Crane loading conditions
Load state is the basic parameters of the sino hoist  is another classification, which indicates that the crane main body - lifting mechanism Loaded severity. Load state with two factors: one is the actual lifting load and rated load Gn G ratio G / Gn, the other is the actual role of G lifting load of work reincarnation total number N Nn ratio N / Nn. Means that G / Gn and N / Nn relationship graph is called load spectrum. Table 1-3 lists the crane load state.
