Today s mine hoists and mine hoist brake systems are a complex combination of elec-trical/electronic, programmable electronic (E/E/PE), hydraulic and mechanical components and systems (other configurations exist). They are well designed by experienced professionals, using time tested and proven design principles and proven and reliable components. Once installed, commissioned and put into commercial operation, they are then operated and maintained by experienced operators and skilled tradespeople. Today s mine hoists and mine hoist brake systems are high performance, reliable systems with a good safety record.
