Yiziphi izimiso zobuchwepheshe ezisetshenziswa ku- isiceli sewundlu?

1. Umshini wokusika amawundlu wehliswa ijubane ngebhande nesitimela segiya, bese kusetshenziswa indlela ye-ratchet ukuxhuma ibhande ukuze kwakhe indlela yokuphakela amakhekhe, futhi uhlangabezane nezidingo zokunyakaza okuphakathi. Ngesikhathi esifanayo, enye isethi yama-pulleys ishayela indlela yesilayidi se-crank ukuze ihambe ukuze ibone ukusikwa kwemvu.

2. Indlela yokuhamba ngezikhathi ezithile yesisiki semvu yemvu ixhunywe nendlela yokunyakaza yommese wokusika. Njengoba inqubo yokusika ifana njalo, ubukhulu besiqephu ngasinye semvu yemvu buyafana. Ubukhulu bocezu bungalungiswa ngokushintsha isivinini sokunyakaza kwezikhawu noma ibanga eliphakathi elidlulisayo.
