JB/T 9725-1999 Method for compiling model numbers of construction machinery products

JB/T 9725-1999 This standard is a revision of ZB J85 019-89 "Method for Compiling Models of Construction Machinery Products". The main changes are as follows. - Pipe cranes are adjusted from the engineering crane category to the earth-moving and transporting machinery category; - The unit of bulldozers and graders is changed from kW to kW×0.735, and the other individual names and models are slightly changed. This standard specifies the principles and methods for compiling models of construction machinery products. This standard applies to excavators, earth-moving machinery, road machinery, construction hoisting machinery, compaction machinery, pile-driving machinery, concrete machinery, steel and prestressed machinery and decoration machinery. This standard was first issued in 1975 as JB 1603-75, and was first revised to ZB J85 019-89 on May 13, 1989. This is the second revision.

Basic principles for determining product model numbers. 3 Structure of product model numbers. 4 Codes for product model numbers. 5 Product model number compilation table. 6 Product examples. IR-T9725-1990. This standard is in line with the ZBJ85019B91 standard for adjusting the mechanical product model number system. Compared with ZDF85019-89, this standard has the following main changes: Adjust the crane category from "mountain crane" to "construction crane" in the original standard to "transport crane on shovel"; Standardize the unit table of "flat crane" Indicated method, Shan W is changed to W×0.735: Other individual names and models have different specifications: According to the relevant provisions of the standard, the compilation has been carried out. This standard replaces the J8501-89 of the 2nd of the year from the date of signing. This standard is proposed and managed by the Technical Committee for Standardization of Construction Machinery.

This standard is applicable to press machinery, earth-moving machinery, road machinery, engineering machinery, compaction machinery, pile-driving machinery, concrete, steel and prefabricated machinery and decoration machinery. 2 Basic principles for determining product models
Product classification principles are to be followed in order to be concise and easy to understand, and to avoid duplication of models of the same type. 3 Composition of product models
Product models are composed of 1. The combination of machine type, model, characteristic code and main number code: If there is an incremental type, update code, batch type, update model number, the suffix of the product model is derived from the product model. The following are shown: Variant and update code
Main number code
Group, model, characteristic codebzxZ.net
4 Product model code
4. Group, version, characteristic code
Group, model, and characteristic codes are all represented by printed uppercase traditional Chinese phonetic letters. The letters are the representative pinyin letters of the model, model and product name (when there is a common model number, other letters can also be used to represent it). The total number of group, model, and characteristic codes shall not exceed three, and at most four. If there is an alphabetic number, the alphabetic number shall be located in front of the product model
4.2 Main parameter code
The main parameter is represented by Arabic numerals. Each model can use the main parameter code as much as possible. 4.3 Variant and Update Code
When the product structure and performance are greatly improved and will be redesigned, trial-produced and identified, its variant and update code shall be A, B, C, D ... Approved by the National Machinery Industry Council on August 6, 1999 and implemented on January 1, 2000
