Some standard content:
JB/T9005.3-1999 This standard adopts DIN15062:1982 Part 2 "Dimensions of crane wire rope pulley hub and support". This standard is a revision of ZBJ80006.3-87 "Types, hubs and bearing dimensions of cast pulleys for cranes". During the revision, only editorial changes were made to the original standard, and the main technical content remained unchanged. This standard is part of the JB/T9005 series of standards "Cast pulleys for cranes", which includes the following 10 parts: JB/T 9005.1-1999 JB/T 9005. 2—1999 JB/T 9005.3—1999bzxZ.net JB/T 9005. 4—1999 JB/T 9005. 5--1999 JB/T 9005.6—1999 JB/T 9005. 7-1999 JB/T 9005. 8-1999 JB/T 9005. 9—1999 JB/T 9005.10--1999 Cast pulley for crane Cast pulley for crane Cast pulley for crane Cast pulley for crane Cast pulley for crane Cast pulley for crane Cast pulley for crane Cast pulley for crane Cast pulley for crane Rope groove section Diameter selection series and matching Type, hub and bearing size Cast pulley for crane Cast pulley for crane Technical conditions This standard replaces ZBJ80006.3-87 from the date of implementation. This standard is proposed and managed by the National Technical Committee for Standardization of Hoisting Machinery. The responsible drafting unit of this standard: Dalian Daqi Group Co., Ltd. The main drafters of this standard: Zhou Yu'an and Cui Zhenyuan. 403 Machinery Industry Standard of the People's Republic of China Casting sheaves for cranes--Type, dimensions of hubs and bearings1 Scope This standard specifies the structural type, hub and bearing dimensions of casting sheaves for cranes. JB/T9005.3-1999 Replaces ZB J80 006.3--87 This standard is mainly applicable to cast wire rope sheaves for bridge cranes and gantry cranes (hereinafter referred to as sheaves). Sheaves for other cranes can also be used for reference. The sheaves referred to in this standard include the balancing sheaves in the wire rope transmission of cranes. 2 Referenced standards The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are all valid. All standards will be revised. All parties using this standard should explore the possibility of using the latest version of the following standards.
