Isethulo esifushane
Igumbi lokuntywila licishe libe ngamamitha angama-85 ubude, amamitha angu-4,5 ububanzi, indawo ejulile cishe ngamamitha ayi-10. Ineshabhu yokusebenzela engaphansi kwamanzi kanye namagumbi asemaceleni, iminyango emithathu enezinkundla kanye nesifaniso sokuphuma egalaji lokupaka (i-shaft enokuvikela ukugibela). Izidumbu ezimbili zezimoto zicwile ezindaweni ezihlukene kanti indawo yokusebenzela engaphansi kwamanzi inamathuluzi amaningi okusebenza ngaphansi kwamanzi (amavalvu, ama-coupling, ama-flange, izakhi zokuxhuma, njll.)
