Requirements for fabricated and cast steel rope rollers, mountings and roller assemblies.

This Part of BS 3876 specifies requirements for fabricated and cast steel rope rollers, mountings and roller assemblies intended for use in colliery track haulage.

This Part applies to

1. rollers, with or without incorporated wind-back facilities and supplied without mountings, for which the diameters of the roller barrels do not exceed the lengths of the rollers to the outsides of their flanges;
2. mounting, either high or low type and dependant upon roller diameters; and
3. roller assemblies that comprise both the rollers and the mountings.

NOTE 1 Appendix A gives the information which should be supplied by the purchaser, in his enquiry and/or order for rollers, mountings or assemblies in accordance with this Part of BS 3876.

NOTE 2 Appendix B gives the information that will be required by the purchaser, to be provided by the supplier, prior to the supply of rollers, mountings or assemblies in accordance with this Part of BS 3876.

NOTE 3 Appendix C gives general recommendations for the design and operating speeds for colliery track haulage rollers.

NOTE 4 No inspection requirements are specified in this Part of BS 3876. However, a typical requirement that the purchaser may choose to write into his order or contract for rollers, mountings or assemblies to this Part is given in Appendix D.
