Ukuthuthuka Kwendima Ye-Roller Chain Embonini 4.0

Njengoba igagasi le-Industry 4.0 lishintsha isimo sokukhiqiza somhlaba wonke, ukusetshenziswa okujulile kobuchwepheshe obufana namarobhothi ahlakaniphile, amawele edijithali, kanye ne-Internet of Things kudonsele ukunaka okukhulu emishinini esezingeni eliphezulu kanye nezinhlelo ezisezingeni eliphezulu. Kodwa-ke, njengomuntu osekhulile emkhakheni wokudlulisa imishini, uchungechunge lwe-roller aluzange luphele ngokushintshashintsha kobuchwepheshe; kunalokho, luye lwashintsha kakhulu kusukela engxenyeni eyisisekelo yokudlulisa kuya endaweni eyinhloko ekukhiqizeni okuhlakaniphile. Kulabo abahileleke kakhulu ebhizinisini lomhlaba wonke lokuthengisa ngobuningi, ukuqonda lokhu kuthuthuka kweminyaka eminingi kuyisihluthulelo sokubamba amathuba ochungechungeni lokunikezela lokukhiqiza olusezingeni eliphezulu.

I. Ukubekwa Ngaphambi Kwemboni 4.0: “Iyunithi Yokudlulisa Eyisisekelo” Ebalulekile

Ngaphambi kokuba kuvele umqondo we-Industry 4.0, i-roller chain yayisisebenze ekukhiqizeni iminyaka eyikhulu, inani layo eliyinhloko libonakala endimeni yalo "njengesithwali sokudlulisa amandla esithembekile." Indima yama-roller chain phakathi nalesi sigaba yayinezici ezihlukile zenkathi:

1. Umthumeli Wamandla Ojwayelekile
Kusukela ngekhulu lama-20, ngokusungulwa kwezindinganiso zomhlaba wonke njenge-ISO 606 kanye ne-ANSI, amaketanga okugoqa akha uhlelo oluhlanganisiwe lokucacisa, lwaba “ibhuloho elijwayelekile” elixhumanisa ama-motor kanye nezindlela zokusebenza. Kusukela ekukhishweni kwamandla kwemishini yezolimo kuya ezinhlelweni zokuhambisa zemigqa yokukhiqiza izimoto, umsebenzi wayo oyinhloko bekulokhu kuwukudlulisela amandla omshini ngempumelelo ku-actuator, ngezidingo ezilinganiselwe zokunemba nobuhlakani. Ukuncintisana kwemakethe ngalesi sikhathi kuvame ukuguqukela emqondweni “wokuhlanganisa imininingwane”, kanti umehluko womkhiqizo ubonakala kakhulu emandleni ezinto ezibonakalayo kanye nezinqubo eziyisisekelo.

2. Ingxenye Engasetshenziswa Engagcinwa Kalula
Kumamodeli okukhiqiza endabuko, amaketanga e-roller ayevamile “njengezingxenye ezigcinwa zingenamsebenzi.” Ngenxa yokuntuleka kwezindlela zokuqapha isimo, izinkampani zazingathembela kuphela ekuhlolweni kwesandla okwenziwa ngomjikelezo ohleliwe kanye nokushintsha, ngokuvamile zibhekene nezinkinga ezimbili: kungaba ukushintshwa kwangaphambi kwesikhathi okuholela ekuchithweni kwezindleko, noma ukungasebenzi kahle okungazelelwe okubangela isikhathi sokungasebenzi komugqa wokukhiqiza. Idatha yomlando evela kwi-German Engineering Federation (VDMA) ikhombisa ukuthi ngaphambi kuka-2010, cishe u-35% wokwehluleka kwesistimu yokudlulisela kwakubangelwa ukwehluleka okungalindelekile kweketanga le-roller, kanye nokulahlekelwa okujwayelekile kwesikhathi sokungasebenzi okungaphezu kuka-$100,000.

3. I-adaptha Yesimo Esisodwa
Amaketanga okugoqa kulesi sigaba ayeyimikhiqizo esetshenziswa kabanzi. Nakuba ayehlangabezana nezidingo eziyisisekelo zokudlulisa, ukuzivumelanisa kwawo nezimo zokusebenza ezikhethekile kwakunganele. Isibonelo, emigqeni yokubhaka eshisa kakhulu embonini yokudla, amaketanga avamile athambekele ekugqwaleni nasekungcoleni; ezindaweni ezisindayo zemishini yechweba, impilo yesevisi yezakhiwo zendabuko ivame ukuba ngaphansi kwamahora ayi-10,000. Ukuntuleka kwamakhono okwenza ngokwezifiso kwenza kwaba nzima ukuphula umkhawulo wenani "lezingxenye ezijwayelekile."

II. Ukuguqulwa Kwendima Okuqhutshwa Yimboni 4.0: Ukuthuthukiswa Okuhlakaniphile Ngezilinganiso Ezintathu

Ngokungena kwe-Intanethi Yezinto, ama-algorithm e-AI, kanye nobuchwepheshe bezinto ezintsha, indima yamaketanga okugoqa isiqalile ukushintsha kakhulu. Ukuvela kwayo akuyona into ephikisana nemisebenzi yendabuko, kodwa kunalokho, ngenkathi igcina izinzuzo eziyinhloko zokudlulisa, inezela amakhono amasha njengokuzwa okuhlakaniphile, ukuxhumana kwedatha, kanye nokusebenzisana kwesistimu, kwakha izinkomba ezintathu eziyinhloko zokuthuthukisa:

1. Kusukela “Kuzingxenye Zomshini” Kuya “Kuma-Intelligent Sensing Node” Ukunciphisa kanye nokunciphisa izindleko zobuchwepheshe bezinzwa kwenze ukuthi amaketanga e-roller abe nekhono lokuzwa imvelo kanye nokuqapha isimo. Amaketanga e-roller aphezulu anamuhla afinyelele imisebenzi “yokuzixilonga”, ebamba idatha yokusebenza ngesikhathi sangempela futhi eyithumela ohlelweni lokulawula ngokuhlanganiswa kwamaketanga anezilinganiso eziningi njengokushisa, ukudlidliza, kanye nomthwalo.

Amaketanga e-roller ahlakaniphile ochungechunge lwe-P4.1 avela enkampanini yaseJalimane i-igus ayisibonelo esihle. Ahlanganisa ama-bearings ashelelayo angenasondlo kanye nezinzwa zokuqapha ezihlakaniphile ekuxhumeni kwezixhumanisi zeketanga. Uma ukuguguleka kufinyelela inani elibalulekile, kukhipha isixwayiso ngokuzenzakalelayo nge-module yokuxhumana ye-i.cee. Izinkampani zasekhaya ezifana ne-Qianjiang Chain nazo zifaka amayunithi okuzwa emaketanga asetshenziswa emishinini yezolimo, zisebenzisa ama-algorithms e-AI ukubikezela imijikelezo yokulungisa, kunciphisa isikhathi sokungasebenzi komugqa wokukhiqiza wenkampani yokudla ngo-28%. Lokhu kuguqulwa kuguqule amaketanga e-roller kusukela "kubathumeli abathule" kwaba "abaqaphi besimo sokukhuluma."

2. Kusukela “Kumikhiqizo Ejwayelekile” Kuya “Kuzinhlelo Ezihlelwe Ngokwezifiso Zesimo” Izidingo zokukhiqiza eziguquguqukayo ezikhuthazwa yi-Industry 4.0 ziqhuba ukuguqulwa kwamaketanga okugoqa kusuka “kuzingxenye ezijwayelekile” kuya “kuzinhlelo ezenziwe ngokwezifiso.” Amaketanga okugoqa esimanje athuthukise uhlelo oluphelele lwezixazululo zezimboni ezahlukene, efinyelela ukufana okunembile ekukhetheni izinto, ukwakheka kwesakhiwo, kanye nokwenza ngcono ukusebenza.

Emigqeni yokuhlanganisa ukuhamba okuxubile kwezimoto, amaketanga e-roller aqoqayo, ngesakhiwo esinamahinji amabili kanye nomklamo wamasondo okungqubuzana, afinyelela ukulawula okuhlakaniphile—”yima lapho ufuna, hamba lapho ufuna.” Ipulatifomu ye-TNGA yakwaToyota, isebenzisa lobu buchwepheshe, ingaqoqa ngasikhathi sinye amamodeli angu-50 ahlukene ngesikhathi sokushintsha kwemizuzwana engu-0. Embonini yokudla, amaketanga e-roller akhethekile enziwe ngensimbi engagqwali engu-304, aqinisekiswe yi-HACCP, afinyelela ukulawula okulinganiselayo kokushisa kanye nomswakama esigabeni sokupholisa ngenkathi ehlangabezana nezidingo zokukhiqiza ezihlanzekile. Ezisetshenzisweni zemishini yechweba, amaketanga e-roller asebenza kanzima asebenzisa inqubo ehlanganisiwe “yokufaka i-carburizing kanye nokucima + izivalo zamafutha ze-PTFE” angagcina ukunemba kokudlulisela okungu-0.02mm ezindaweni ezisukela ku--40℃ kuya ku-120℃, kanye nokuphila kwenkonzo okungaphezu kweminyaka engu-15.

3. Kusukela “Kuzingxenye Ezizimele” Kuya “Kukwakheka Kwamawele Edijithali” Ukusetshenziswa kobuchwepheshe bamawele edijithali kuvumela amaketanga okugoqa ukuthi ahlanganiswe ngokugcwele kunethiwekhi iyonke yokukhiqiza okuhlakaniphile. Ngokwakha isibuko sedijithali salolu chungechunge esikhaleni esibonakalayo, ukuphathwa okubonakalayo kanye nokwenza ngcono kulo lonke umjikelezo walo wokuphila kungafezwa.

Ngesikhathi sesigaba sokuklama, izinkampani zisebenzisa ubuchwepheshe bokulingisa ukuze zenze ngcono izakhiwo ze-chain link. Isibonelo, ukwakheka kwepuleti eliphezulu elinomumo we-crescent, ngokusebenzisa ukulingisa ukusatshalaliswa kokucindezeleka, kuthuthukisa ukusebenza komthwalo ophikisana ne-eccentric ngo-40% ngenkathi kunciphisa ukusetshenziswa kwamandla okudlulisa ngo-8%-12%. Esigabeni sokukhiqiza, ukuhlanganiswa kwezinhlelo ze-ERP kanye nemishini yokuhlola yedijithali kudala inqubo evaliwe kusukela ekuklanyweni kuya ekukhiqizweni kuya ekuhlolweni kwekhwalithi. I-Qianjiang Chain isebenzisa ukuhlolwa okubonakalayo okuzenzakalelayo okungu-100% ukulawula amaphutha okudlulisa ngaphakathi kwe-0.1mm. Esigabeni sokusebenza nokulungisa, izinhlelo zokubikezela impilo ye-chain drive ezakhiwe yizinkampani ezifana ne-ABB zingathuthukisa ukunemba kwesixwayiso samaphutha kube ngu-92%, ziguqule ukulungiswa kusuka "ekulungiseni okungasebenzi" kuya "ekuhleleni okusebenzayo."

III. Izimo Zokusetshenziswa Okuyinhloko: Inani Elisebenzayo Eliboniswa Ekukhiqizeni Okuhlakaniphile

Ukuthuthuka kwendima ye-roller chain akuyona nje ukuthuthukiswa komqondo okungokwemfundiso, kodwa ukwakhiwa kabusha kwenani okufakazelwe ezimweni ezahlukahlukene zezimboni. Izici zayo ezihlakaniphile ziba usizo olubalulekile ekuthuthukiseni ukusebenza kahle kokukhiqiza ezindaweni ezibalulekile:

1. Imigqa Yokuhlanganisa Izimoto Ehlakaniphile: “Izinzwa Zokudlulisa” Zokukhiqiza Okuguquguqukayo
Emkhakheni wokukhiqizwa kwezimoto ezintsha zamandla, amaketanga e-roller abe yingxenye eyinhloko yokukhiqizwa okuguquguqukayo. Umugqa wokuhlola ohlakaniphile wama-air conditioner e-Gree usebenzisa uhlelo lwe-roller chain oluqoqayo, olukwazi ukuqoqa amayunithi angu-200 angaphakathi ngaphakathi kwendawo ye-buffer yamamitha angu-15. Lokhu kufana ngokuguquguqukayo nesigqi sokuhlola samayunithi angaphandle, kufinyelela izinga lokubanjwa komkhiqizo elinephutha elingu-100%. Ngemuva kwalokhu kuguquguquka okuguquguqukayo kukhona ukubambisana okujulile phakathi kwe-roller chain kanye nezinhlelo ze-PLC/SCADA. Ngokubeka okuhlanganisiwe okubili kusetshenziswa ama-laser rangefinders kanye nabafundi be-RFID, kufinyelela ukulandelela okunembile kwezimoto ezingaphezu kuka-1000 ngokunemba kokubeka okungu-±1mm. Ngokusho kwedatha evela kwi-China Association of Automobile Manufacturers, ngo-2024, izinhlelo zokuhambisa ezingaphezu kuka-70% ezimbonini zezimoto ezintsha zamandla ezakhiwe zamukela izixazululo ze-roller chain ezihlakaniphile, ezinobude obumaphakathi beketanga obungamakhilomitha angu-8.2 efektri ngayinye.

2. Ukuhlela Okuhlakaniphile Kwezokuthutha: “Amandla Ayinhloko” Okuphumelela Kakhulu
Emkhakheni we-logistics ezenzakalelayo, ukuthuthukiswa okuhlakaniphile kwamaketanga okugoqa kuholele ngqo ekwandeni okukhulu ekusebenzeni kahle kokuhlunga. I-JD.com's Asia No. 1 warehouse isebenzisa uhlelo lwe-smart sorting chain olulungisa ngokuguquguqukayo isikhala sephakheji, lufinyelele umthamo wokucubungula ophezulu wamaphakheji angu-200,000 ngosuku ngokunemba kokuhlunga okungu-99.99%. Lokhu kusebenza okuphezulu kuvela ezinqubweni ezimbili zobuchwepheshe: okokuqala, amaketanga okugoqa anobubanzi obuphindwe kabili anobuso obufakwe i-nickel, okwandisa umthamo wokuthwala umthwalo ube ngu-3000 kg/m kanye nesikhathi sokuphila esingaphezu kwamahora angu-80,000; okwesibili, ukuhlanganiswa kwamayunithi okushayela asakazwayo kanye nama-algorithms ahlakaniphile, kunciphisa ukusetshenziswa kwamandla ngo-35% uma kuqhathaniswa nezinhlelo zendabuko. I-International Energy Agency (IEA) ilinganisela ukuthi ukusetshenziswa kwezinhlelo ezinjalo zokudlulisa ezihlakaniphile kungathuthukisa ukusebenza kahle kwamandla okuphelele kwemishini yezokuthutha ngo-18%-22%.

3. Imishini Emisha Yamandla: Umlingani Othembekile Ezindaweni Ezibucayi Emikhakheni yamandla omoya, amabhethri e-lithium, kanye neminye imishini emisha yamandla, indima yamaketanga okugoqa ishintshe kusukela ezingxenyeni ezijwayelekile zokudlulisa kuya “ochwepheshe bokuzivumelanisa nezimo.” Ngenxa yendawo engaphandle enzima yezindlela zokuphakamisa i-turbine yomoya, izinkampani zithuthukise amaketanga okugoqa akhethekile angagqwali. Ngobuchwepheshe bokumboza nge-graphene, ukumelana nokuguguleka kuthuthukiswa ngo-40%, futhi impilo yesevisi idlula amahora angu-50,000 ezindaweni ezisogwini ezinomswakama ophezulu. Emakamelweni ahlanzekile asetshenziswa ekukhiqizweni kwebhethri le-lithium, amaketanga okugoqa anezakhiwo ezivalekile ngokuphelele kanye nezinto zokugcoba zokudla zithola ukusebenza okungenazinhlayiya, zihlangabezana nezindinganiso zokuvikela ze-IP67. Ukuvela kwale mikhiqizo eyenziwe ngokwezifiso kuye kwaholela ekunciphiseni okungaphezu kuka-65% kwesilinganiso sokwehluleka kwezinhlelo zokudlulisa emishinini emisha yamandla.

4. Imishini Enzima: “Abaqaphi Abahlakaniphile” Bezimo Ezinzima
Ezimweni ezinzima njengezikhumulo zemikhumbi nezimayini, amaketanga e-roller ahlakaniphile abhala kabusha izindlela zokulungisa zendabuko. Amaketanga e-roller ahlanganisiwe e-sensor asetshenziswa e-Qingdao Port angaqapha izinga lokushisa kwesixhumanisi seketanga kanye nedatha yokudlidliza ngesikhathi sangempela, futhi, ngokubambisana namasango e-edge computing, anikeza izexwayiso zamaphutha okuqala, andise isikhathi sokusebenza esisebenzayo semishini ye-crane ngo-20%. Inani elilethwe yilokhu kuthuthukiswa kobuchwepheshe libalulekile: ngokusho kombiko ka-2024 we-National Institute of Standards and Technology (NIST), imishini esindayo esebenzisa amaketanga e-roller ahlakaniphile ithola ukwehliswa okumaphakathi kwezindleko zokulungisa okungu-32% kanye nokwenyuka kokusebenza kahle okuphelele okungu-15%.

IV. Umbono Wokuthengisa Okuthengiswayo Kwamazwe Ngamazwe: Ukusebenzisa Amathuba Emakethe Ekuguqukeni Kwendima

Ukuguqulwa kwendima ye-roller chain akugcini nje ngokuguqula inani layo lezimboni kodwa futhi kuvulele amathuba amasha okukhula kumakhasimende aphesheya kwezilwandle. Bebhekene negagasi lomhlaba wonke lokuguqulwa okuhlakaniphile ekukhiqizeni, abathengisi bezitolo ezinkulu badinga ukuhlela kabusha i-logic yebhizinisi labo kusukela ezicini ezintathu:

1. Shintsha Isakhiwo Somkhiqizo Siye Emikhiqizweni Esezingeni Eliphezulu
Idatha yemakethe ikhombisa ukuthi isidingo somhlaba wonke samaketanga e-roller aphezulu siyashesha: isilinganiso sesidingo somkhiqizo ophezulu sikhuphuke sisuka ku-35% ngo-2022 saya ku-47% ngo-2025, kanti amaketanga e-roller ahlakaniphile abonisa izinga lokukhula lonyaka elihlanganisiwe elidlula u-12%. Kwabathengisi abaningi, ukugxila ezigabeni ezintathu eziyinhloko zomkhiqizo kuzohlinzeka ngenzuzo yokuncintisana: okokuqala, amaketanga okuqapha ahlakaniphile anezinzwa ezihlanganisiwe, ezifanele kakhulu izimakethe zokukhiqiza eziphezulu eYurophu naseMelika; okwesibili, imikhiqizo eyenziwe ngokwezifiso yezimo zokusebenza ezikhethekile, njengeketanga lensimbi engagqwali yezinga lokudla kanye namaketanga amelana nokugqwala okushisa okuphezulu, angahlangabezana nezidingo zezimboni ezintsha zamandla nokudla eNingizimu-mpumalanga ye-Asia; kanti okwesithathu, izinhlelo zamaketanga eziguquguqukayo, njengeketanga ze-accumulator conveyor, ezingahambisana nokuthuthukiswa kokukhiqiza okuguquguqukayo kwemboni yezimoto yomhlaba wonke.

2. Yandisa Amakhono Esevisi Ekuqondisweni Kwesistimu
Ngokomongo we-Industry 4.0, amakhasimende awasadingi imikhiqizo yochungechunge olulodwa, kodwa izixazululo zokudlulisa eziphelele. Amamodeli aphumelelayo athengisa ngobuningi ashintshe kusukela "ekulethweni komkhiqizo" kuya "ezinsizeni zenani": ukuhlinzeka ngokusekelwa kusukela ekuqaleni kuya ekugcineni okuhlanganisa ukukhethwa kochungechunge, isiqondiso sokufaka, kanye nokuhlanganiswa kwedatha; ukusiza amakhasimende ekuhlanganiseni idatha yochungechunge ezinhlelweni zawo ze-SCADA noma ze-MES ezikhona zokubambisana kwamapulatifomu ahlukahlukene; ngisho nokunikeza iziphakamiso zokulungisa nokwenza ngcono ngokusekelwe kudatha yokusebenza eqoqwe. Okuhlangenwe nakho kwe-Hangzhou Qianjiang Chain kukhombisa ukuthi izinkampani ezihlinzeka ngezixazululo zesistimu zinezinga lokuthenga kabusha kwamakhasimende eliphakeme ngo-40% kunabathengisi bomkhiqizo abavamile.

3. Ukuhlelwa Kwe-Supply Chain Ukuzivumelanisa Nokuguquguquka Komhlaba Izindlela ezahlukene zokuthuthukiswa kwe-Industry 4.0 ezifundeni ezahlukene zinquma izici ezihlukile zesidingo se-roller chain. Ezimakethe zaseYurophu naseMelika, i-Carbon Border Adjustment Mechanism (CBAM) idinga ukwanda okungu-45% ekuthengweni kwezintambo ezinobungani nemvelo, okudinga abathengisi bezitolo ezinkulu ukuthi babeke phambili ukugcinwa kwemikhiqizo eluhlaza engasetshenziswa kabusha, engasetshenziswa kabusha. Emakethe yaseNingizimu-mpumalanga ye-Asia, ukukhula okukhulu kwezimoto ezintsha zamandla kanye nokukhiqizwa kwe-elekthronikhi kuye kwakhuthaza isidingo sezintambo ezincane ezihlakaniphile ezinembile, ezisezingeni eliphansi, kanye namazinga okukhula kwesidingo saminyaka yonke emazweni afana neVietnam ne-India afinyelela ku-18%-22%. Emakethe yase-Afrika, umjikelezo omfushane wokushintshana kwemishini yezimayini ezijulile uholele esilinganisweni sokukhula saminyaka yonke esingu-15% sesidingo sezingxenye ezisele zezintambo ezisindayo.

V. Amathuba Amasha Endima Esikhathini Sokuxhumana Okuhlakaniphile

Njengoba i-Industry 4.0 ijula, indima yamaketanga okugoqa iyaqhubeka nokukhula ngesivinini esikhulu. Eminyakeni emihlanu ezayo, izitayela ezintathu ezinkulu zizophinde zishintshe ukuma kwayo kwezimboni:

Ezingeni lobuchwepheshe, ukusetshenziswa okujulile kwamamodeli edatha enkulu ye-AI kuzokwenza kube lula ukugxuma kusuka "ekulungiseni okubikezelayo" kuye "ekulungiseleleni okubikezelayo." Ngokuhlaziya inani elikhulu ledatha yokusebenza, uhlelo lungalungisa ngokuzenzakalelayo amapharamitha afana nokuxinana kweketanga kanye nemijikelezo yokugcoba ukuze kulondolozwe ukusebenza kahle kokudlulisa. Ucwaningo olwenziwe yiBeijing Zhongdao Taihe lubonisa ukuthi izinhlelo zeketanga ezilungiselelwe i-AI zinganciphisa ukusetshenziswa kwamandla ngo-10%-15%.

Ensimini yezinto zokwakha, ukusetshenziswa kwezinto ezintsha ezihlanganisiwe kuzodlula imingcele yokusebenza ngokomzimba. Amandla okuxhunywa kwamaketanga e-titanium alloy akhuphuke ngo-35% uma kuqhathaniswa nemikhiqizo yendabuko, kuyilapho isakhiwo esihlanganisiwe samapulasitiki obunjiniyela nezinsimbi sinciphisa isisindo seketanga ngo-40% ngenkathi siphinda kabili isikhathi saso sokuphila. Lokhu kusungulwa kwezinto zokwakha kuzoholela ekuthuthukisweni kokusetshenziswa kwamaketanga e-roller emikhakheni ephezulu njengezindiza kanye ne-elekthronikhi enembile.

Ezingeni lemvelo, amaketanga e-roller azoba ama-data node abalulekile ku-Inthanethi Yezimboni. Ngokuxhuma kumapulatifomu efu lezimboni zomhlaba wonke, idatha yokusebenza kwamaketanga evela ezinkampanini ezahlukene ingabiwa ngokungaziwa, kwakha amamodeli okuxilongwa kwamaphutha ezingeni lemboni kanye nezindinganiso zokulungisa. Lokhu kubambisana kwezemvelo kuzoshintsha ngokuyisisekelo imodeli yokukhiqiza kanye nensizakalo yamaketanga, ishintshe kusukela "ekukhiqizeni kwebhizinisi elizimele" iye "ekusunguleni ngokubambisana kwemboni."

Isiphetho Kusukela engxenyeni eyisisekelo yokudlulisa eminyakeni eyikhulu edlule kuya endaweni ebalulekile ekukhiqizeni okuhlakaniphile kwanamuhla, ukuvela kwendima ye-roller chain kuqinisekisa iqiniso elilula: egagasini lokuguquka kwezimboni, imikhiqizo yakudala ngempela ayikaze yesabe ukuphindaphinda kobuchwepheshe, kodwa kunalokho iqhubeka nokuvuselelwa ngokuzivuselela. Kumakhasimende aphesheya kwezilwandle, lokhu kuguquka kuveza izinselele kanye namathuba - labo abangaqonda ngokunembile izindima ezishintshayo futhi baphendule ngokushesha ezidingweni zemakethe ekugcineni bazoba nesikhundla esiyinhloko ohlelweni lokuhlinzeka ngokukhiqiza okuhlakaniphile emhlabeni jikelele.
