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.
