1.Crane use levelZ5iHenan Dongqi Machinery Co., Ltd
Crane has certain work cycles during the useful life time. Crane operation work cycle is the whole operation process starts from the preparing of lifting items, until the next lifting. Total work cycles show crane utilization degree, it is one of the basic parameters of crane level classification. Crane total work cycle is the sum of crane working cycles during the service life.Z5iHenan Dongqi Machinery Co., Ltd
When determine the appropriate crane service life, it need to consider the economic, technical and environmental factors, and also need involve the influence of equipment aging.Z5iHenan Dongqi Machinery Co., Ltd
Total number of work cycle is associated with the use frequency of crane. For convenience, the total number of work cycle in the possible range, divided into 10 use levels (U0 to U9), shown in the following table.Z5iHenan Dongqi Machinery Co., Ltd

3. Crane classificationZ5iHenan Dongqi Machinery Co., Ltd
Crane classification is also called crane level classification which is determined by crane using level and load condition, crane work level with the symbol of A, its working level are divided into 8 grades, namely A1 ~ A8. Z5iHenan Dongqi Machinery Co., Ltd
