In the past, as the main technical parameters of cranes, the JC% value was often mentioned to indicate the level of the crane, such as light, medium, or heavy, which is the so-called "work system". With the development of crane technology, it is obvious that the technical concept and meaning of the crane working system have considerable defects and deficiencies because the crane working system only considers the power-on time of the crane
The length of the crane to determine the level of the crane is very unreasonable.
Nowadays, one of the main technical parameters of a crane is the working level of the crane, which replaces the unreasonable working system in the past.
The working level of the crane is determined by two kinds of abilities, one of which is starting
The frequency of heavy machinery use is called the crane utilization level; the second is the crane's load
The size of the crane is called the load state of the crane.
