“…Number of publications deal with the issues of structural components, such as drums, friction pulleys (Wolny & Badura, 2012), sheaves (Grobler, 2005;Dumitrescu et al, 2015), brakes (Kowal et al, 2012;Ungureanu et al, 2017a) and drives (Tiley, 1993), cages (skips) and hoist steel wire ropes (Stanova et al, 2015;Šaderová, 1997). Some authors describe hoisting machines used in practice (Despodov et al, 2012;Johansson, 2005), some deal with safety issues (Hayes, 2011) and maintenance (Vayenas & Wu, 2011), others evaluate engagement of vertical conveyance in comparison with other available conveyance systems, e.g., conventional shaft hoisting and flexowell vertical belt applications (Gonen at al., 2012), vertical shaft and a ramp system (Elevli et al, 2002). Authors also present modernisation and reconstruction of existing hoisting machines (Despodov & Panov, 2015;Wang, 2014).…”
