| BSI | 2018 | 38 |
This document specifies the loads, the load combinations and the design procedures for the design of the steel and aluminium alloy structural members of conveyances used for the transport of personnel, materials, equipment and rock in vertical and decline shafts. The conveyances covered by this document include personnel or material cages (or both), skips, kibbles, equipping skeleton cages, inspection cages, bridles, crossheads and counterweights.
This document is not intended to be used for the design of ropes, sheaves or attachments. Rope sizes are determined in accordance with other standards.
This document does not cover chairlifts.
This document does not cover matters of operational safety or layout of conveyances.
This document adopts a limit states design philosophy.
