Imishini Yokucindezela Ngendlela Esheshayo (Drop Weight)

Imishini yokucindezela okuqhubekayo (i-drop weight) idlala indima ebalulekile emkhakheni wezisisekelo ezijulile kanye neziqinisekiso zemikhakha yobufundisi, ihlinzeka ngesisombululo esisebenza kahle sokuthuthukiswa komhlaba nokuzinzisa umhlabathi. Le mishini ikhethekile isebenzisa umgomo wokukhanda ukufaka umthwalo owanelisayo kumhlabathi ngokucindezela umhlabathi ngokuqhubekayo kwehlelwa kokuhlukile umthwalo onzima ukusuka phezulu okukhawulelwe. Le nqubo ibandakanya ukuhamba okuhlelwe kokwehliswa komthwalo phezu kobubanzi bezwe, kudala ingcindezi enkulu emhlabathini ethuthukisa amandla nokuzinza komhlabathi. Ukuze ukusebenza kwemishini yokucindezela okuqhubekayo kube lula kodwa kusebenze kahle. Umthwalo wehla, ophakathi kwabantu abaningana noma ngaphezulu kwamathani amabili, uthathwa phezulu kusetshenziswe i-crane noma i-rig ekhethekile. Umthwalo uthululwa, uthinte ububanzi bezwe, okwaholela ekudlulisweni okusheshayo kwamandla emalengeni. Le ndlela ayicindezeli kuphela amazinyo aphezulu omhlabathi kodwa futhi idlulisa amandla ngaphakathi kwezakhiwo zomhlabathi, ifinyelela ezinhlelweni ezinhle kakhulu ngesikhathi esifushane. Ukusebenza kahle kwale ndlela yokucindezela kwenza kube nezinzuzo ezinkulu ekubhekaneni nomhlabathi ophukile, okwandiswe ngezinye zezinto ezidinga ukuthuthukiswa ngaphambi kokwakhiwa, njengezikhumbuzo, izisekelo, noma ezinye izakhiwo ezinzima. Izinhlelo ezisemqoka zezimoto zokucindezela okuqhubekayo zifaka phakathi ukulungiselela izindawo zokuthuthukiswa okukhulu, izinhlelo zokwakha, kanye nokuthuthukiswa kwezimoto ezaphazamiswa ngaphambili. Ivame ukusetshenziswa ezindaweni zasemadolobheni lapho izimo zomhlaba kufanele zithuthukiswe ukuze kusekele izakhiwo eziphakeme, izakhiwo ezithengiswayo, kanye nezinsizakalo zokuhamba ezifana namabhuloho nezindlela. Ukukwazi ukuhamba ngokushesha umhlabathi ngaphandle kokuphazamiseka okukhulu kwenza ukuthi ucindezelwe okuqhubekayo kube ukukhetha okuhle kakhulu kwezimali ezidinga isikhathi esisheshayo sokuphendula ngaphandle kokwehla kumgangatho. Uma kukhethwa imishini yokucindezela okuqhubekayo, izpecifications eziningana nezimfuneko ziba nendima. Izici ezibalulekile zifaka phakathi isisindo somthwalo wehla, ukuphakama okuphelele kokuthi kuwehliswe khona, nokuphindaphinda kokukhanda. Izincazelo zempahla ngokuvamile zihluka ngokuya ngezidingo zephrojekthi, izimo zomhlabathi, kanye nezinga lokucindezela elifunwayo. Ngaphezu kwalokho, abaphathi kufanele bacabangele usayizi wendawo yokusebenza, ukufinyelela komshini, nezinhlinzeko zemvelo. Ukukhetha imishini kungaba nomthelela omkhulu kokubili ekuqhenyweni nasekusebenzeni kahle kwezinqubo zokucindezela, okwenza kube kubalulekile ukuhambisa amandla emishini nezidingo ezithile zephrojekthi. Ngokufingqa, imishini yokucindezela okuqhubekayo (i-drop weight) iyithuluzi elibalulekile emkhakheni wezisisekelo ezijulile kanye neziqiniseko zemikhakha yobufundisi, ihlinzeka ngesisombululo esheshayo, esisebenza kahle sokuthuthukiswa komhlaba. Ikhono layo lokuthuthukisa ukuzinza komhlabathi kanye namandla okuphathwa komthwalo kwenza kube ukukhetha okuthandwayo kwezinhlobonhlobo zezicelo zokwakha, ukuqinisekisa ukuphepha nokuphila kwezakhiwo ezakhiwe emhlabeni othuthukile. Ngokwazi imishini, izicelo, nezimfuneko zokukhetha, ochwepheshe embonini bangathatha izinqumo ezinolwazi uma bethenga noma beqasha le mishini ebalulekile kwiwo ambiri.
