BSI BS 3876-5:1990

This Part of BS 3876 specifies requirements for suspended pulley assemblies and clamps intended for use in colliery track haulage.

This Part applies to:

  • suspended pulleys, supplied and used with or without mountings, that are intended for the support of haulage ropes and which may be used in rope haulage ancillary equipment, e.g. weight ropes on safety equipment, haulage rope tensioning equipment, etc.;
  • mountings;
  • suspended pulley assemblies that comprise the pulleys and mountings;
  • clamps for suspending assemblies from supporting members.

The suspended pulleys to which this Part applies are not intended to be used where rope deflections in excess of 10° across a single pulley are required. Where rope deflections in excess of 10° per pulley are required, pulleys in accordance with BS 4878 should be used.

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

NOTE 3 Appendix D gives general recommendations for the design and operating criteria for suspended pulleys.

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

NOTE 5 The titles of the publications referred to in this Part of BS 3876 are listed on the inside back cover.
