Specifies requirements for general purpose sheave blocks for lifting purposes that meet the performance requirements of the M3 group classification of crane mechanisms as specified in AS 1418.1. This Standard does not cover power-operated sheave blocks specifically for use with natural fibre ropes or synthetic filament ropes, sheave blocks used for lightweight lifting in the building industry and for general materials handling (known as 'gin blocks'). Guidance on information that should be supplied with enquiries and orders on care and use, on use of ships' cargo blocks and on use for non-lifting applications, is given in appendices.

This Standard specifies requirements for general purpose sheave blocks for lifting purposes that meet the performance requirements of the M3 group classification of crane mechanisms as specified in AS 1418.1.This Standard does not cover power-operated sheave blocks specifically for use with natural fibre ropes or synthetic filament ropes, or sheave blocks used for lightweight lifting in the building industry and for general materials handling (known as 'gin blocks').NOTES:1 Sheave blocks used for applications other than lifting may have sheaves that are smaller in diameter than those specified herein.2 This Standard covers sheave blocks with any type of bearing (i.e. frictionless or friction) and with any type of operating means (i.e. power driven or manual).3 Guidance on information that should be supplied with enquiries and orders is given in Appendix A.4 Standards for components that are used in lifting systems are listed in Appendix B.5 Guidance on care and use is given in Appendix C.6 Guidance on applications of ships' cargo blocks is given in Appendix D.7 Guidance on use for non-lifting applications is given in Appendix E.
