This study summarises the research efforts undertaken to establish how variable stiffness of shaft steelwork should affect the amplitudes of horizontal displacements of selected components of a conveyance (skip head and skip bottom frame). Most studies investigating the dynamic behaviour of conveyances travelling in the shaft rely on a simplifying assumption whereby the shaft steelwor... https://www.jmannino.com/best-catch-Sophie-Allport-Bee-Blackout-Ready-Made-Eyelet-Curtains-Duck-Egg-special-save/
