- Izinhlelo ze-GET ezinama-tippet ahlanganisiwe zinciphisa izindleko zokusebenza ngethani ngalinye ngo-30-40% uma kuqhathaniswa nezinhlelo zensimbi eyodwa, kodwa zethula ingozi yokuhluleka kokushintshwa — Ngincoma izinhlelo zama-tip ahlanganisiwe emisebenzini yemigodi lapho ikhwalithi yokushintshwa ingenakuqinisekiswa khona ngokwezindinganiso zokucaciswa kwezimayini.
Engikufundile Mayelana THOLA Incazelo Yama-Quarry Bulldozer Ngemva Kweminyaka Eyi-10 Yokunikezwa Kwezingxenye Zokugqoka Zezimayini
Ngesikhathi ngiqala ukuhlinzeka ngamathuluzi okubandakanya umhlabathi (i-GET) emisebenzini yokumba izimayini ngo-2015, iphutha elivame kakhulu engalibona abaphathi bokulungiswa kwemikhumbi yezimayini benza kwaba ukucacisa imiphetho ye-GET ngokusekelwe entengo kuphela — ukuthenga inketho eshibhile kakhulu engafanela imishini yabo ngaphandle kokucabangela ukuklwebheka kwezinto zokumba, amahora okusebenza ngosuku, noma izindleko eziphelele zokusetshenziswa kwe-GET phakathi nesikhathi sokusetshenziswa kwemishini. Umphumela waba ukuguguleka kwangaphambi kwesikhathi (lapho insimbi yezinga eliphansi isetshenziswa ezimweni zokuklwebheka okuphezulu) noma izindleko eziphakeme (lapho amathiphu e-tungsten carbide esezingeni eliphezulu asetshenziswa ezimweni zokuklwebheka okuphansi lapho insimbi ejwayelekile ephathwa ngokushisa yayinganele).
Eminyakeni eyi-10 edlule, ngihlinzeke ngemikhiqizo ye-GET emisebenzini yokumba kulo lonke elaseNingizimu-mpumalanga ye-Asia, eMpumalanga Ephakathi, nase-Asia Ephakathi, kusukela ezinkwalini ezincane ze-limestone eziqhutshwa ngumndeni ezikhiqiza amathani angu-50,000 ngonyaka kuya emisebenzini emikhulu yokumba i-granite ekhiqiza amathani ayizigidi ezimbili ngonyaka. Ngiye ngenza izifundo zesilinganiso sokuguguleka, ngahlaziya izindleko eziphelele zokusetshenziswa kwe-GET ngethani lezinto ezithuthwayo, futhi ngasebenza namaqembu okulungisa ukuze ngenze ngcono izikhawu zokushintsha kwe-GET kanye nemikhuba yokusebenza. Engikufundile ukuthi imininingwane ye-GET iyisinqumo sobunjiniyela esiqhutshwa idatha, hhayi isinqumo sokuthenga, nokuthi imininingwane efanele inganciphisa izindleko ze-GET eziphelele ngo-30-50% uma kuqhathaniswa nencazelo engenalwazi esekelwe ezindleleni zokuqala eziphansi kakhulu.
Ukuqonda Ubuchwepheshe be-GET: Izinhlelo Zensimbi Eyodwa Uma Ziqhathaniswa Nezicucu Ezihlanganisiwe
Amathuluzi okubandakanya umhlabathi wama-bulldozer e-quarry atholakala ngezindlela ezimbili eziyinhloko zohlelo: insimbi eyodwa (lapho i-adaptha kanye nonqenqema oluphambili kuyi-cast eyodwa noma ingxenye eyenziwe ngobumba) kanye ne-tippet ehlanganisiwe (lapho i-tip ehlanganisiwe ehlanganisiwe ihlanganiswa noma iboshwe ngomshini kwi-adaptha yensimbi). Ukukhetha phakathi kwalezi zinhlelo kunemiphumela ebalulekile ezindleleni zokusebenza, umkhuba wokulungisa, kanye nengozi yemishini.
Izinhlelo ze-GET zensimbi eyodwa
Izinhlelo ze-GET zensimbi eyodwa ziyindlela yendabuko yokusika imiphetho ye-bulldozer futhi zihlala ziyindinganiso emisebenzini eminingi yokumba. Ingxenye yonke — kusukela emshinini wokukhiya obamba i-shank ye-dozer blade kuya emphethweni wokusika othinta izinto zokumba — iyingcezu eyodwa yensimbi ye-alloy ephathwe ngokushisa. Lapho unqenqema lokusika luguga noma luphuka, yonke ingxenye iyasuswa bese ithathelwa indawo entsha.
Izinzuzo zezinhlelo zensimbi eyodwa ukulula (akukho ukushintshwa okufanele kugcinwe, akukho hardware yokugcina amathephu okufanele ihlolwe, futhi akukho bungozi bokulahlekelwa amathephu ngesikhathi sokusebenza) kanye nokuthembeka (i-GET yensimbi eyodwa efakwe kahle ngeke yehluleke ngendlela ebangela ukulimala kwe-blade). Ububi yizindleko: lapho unqenqema olusikiwe luguga ngemva kwamahora angu-200-600 okusebenza, yonke ingxenye - kufaka phakathi ingxenye ye-adaptha engakaze iguge nhlobo - kumele ishintshwe. Ukuze uthole izinto zokwakha ezigugile kakhulu lapho unqenqema olusikiwe luguga ngokushesha, lokhu kusho ukuthi kufanele kushintshwe i-adaptha engagqokwanga engu-70-80% njalo emahoreni angu-200-400, okuyinto echitha imali ngokwezomnotho.
Izinhlelo ze-GET ezihlanganisiwe
Izinhlelo ze-GET ezinama-tippet ahlanganisiwe zibhekana nokungasebenzi kahle kwezomnotho kwezinhlelo zensimbi eyodwa ngokuhlukanisa ingxenye yokuguguleka (isihloko) nengxenye yesakhiwo (i-adaptha). Lapho i-tip iguga, i-tip kuphela eshintshwayo — i-adaptha ihlala ifakiwe ku-dozer blade, bese i-tip entsha ishintshwa noma ivalwe ngomshini endaweni yayo. Emisebenzini ye-quarry ephezulu, lokhu kunganciphisa izindleko zokusebenza ze-GET ngo-30-40% ngoba izindleko ze-adaptha ziyancishiswa ngenxa yokushintsha ama-tip amaningi.
Kodwa-ke, izinhlelo ze-welded-tippet zethula izingozi ezingekho ezinhlelweni zensimbi eyodwa. I-weld ephakathi kwe-tip kanye ne-adaptha iyinhlanganisela ebalulekile yesakhiwo ebhekene nokucindezeleka okuphezulu kokujikeleza okuvela ku-冲击 kanye nokuhuzuka kwezinto ze-quarry. Uma i-weld ingenziwanga ngokwezidingo zemayini (ngokuvamile i-AWS D14.1 noma okulingana nayo), noma uma i-weld ingahlolwa njalo ukuze kutholakale imifantu nokukhathala, ukwehluleka kwe-tip weld ngesikhathi sokusebenza kungabangela ukuthi i-tip iphuke futhi ibe yi-projectile enejubane eliphezulu ngaphakathi kwe-quarry, noma kungabangela umonakalo ku-dozer blade ebiza izikhathi eziphindwe ka-5-10 kunezindleko ze-GET zokulungisa. Ngokwami, ingozi yokuhluleka kwe-weld yisona sizathu esiyinhloko esenza abanye abaqhubi be-quarry bakhethe izinhlelo zensimbi eyodwa - bamukela izindleko eziphezulu zokushintsha ngokushintshana ukuze kuqedwe ingozi yokuhluleka kwe-weld.
Inketho yesithathu egwema kokubili ukungasebenzi kahle kwezindleko zensimbi eyodwa kanye nengozi yokushisela ye-tippet eshisiwe uhlelo lwe-tip yokukhiya ngomshini, lapho i-tip ibanjwa ku-adaptha uhlelo lokugcina lwemishini (iphini lokukhiya, i-SetRing, noma uhlelo lwe-wedge) kunokuba lushiselwe. Amathiphu okukhiya ngomshini angashintshwa ngemizuzu emi-5-10 (uma kuqhathaniswa nemizuzu engama-30-60 ye-tip eshisiwe), futhi aqeda ngokuphelele ingozi yokuhluleka kokushisela, kodwa adinga ukuhlolwa njalo nokugcinwa kwendlela yokukhiya ukuqinisekisa ukuthi amathiphu awalahleki ngesikhathi sokusebenza. Ngincoma kakhulu izinhlelo zokukhiya ngomshini zemisebenzi ye-quarry lapho ikhwalithi yokulungisa iguquguquka khona futhi lapho imiphumela yesigameko sokulahlekelwa yi-tip iba mibi kakhulu.

Kuma-bulldozer ekilasi angu-520HP, nciphisa izikhawu cishe ngo-20%. Hlola ushintsho ngalunye (njalo emahoreni angu-8-12) bese ushintsha uma ikhala lethiphu ligugile lifinyelele ngaphakathi kwe-10mm yehlombe le-adaptha, noma yikuphi ukuqhekeka okubonakalayo kusuka ekhaleni kuya ku-adaptha kudlula u-5mm, noma ukwehla kwesisindo kudlula u-15% wokuqala. Ukusebenza ngalezi zindlela kwandisa kakhulu ingozi yesibili yokulimala.
Ukukhethwa Kwamazinyo Ebhakede Kwabambi Bemigodi Ezicelweni Zokumba Nokumbiwa Kwemigodi
Nakuba lesi sihloko sigxile ku-bulldozer GET yemisebenzi yokusunduza, imikhumbi yezimayini ze-quarry ngokuvamile isebenzisa ama-bulldozer kanye nama-excavator, futhi izimiso zokucaciswa kwe-GET zamazinyo ebhakede le-excavator zihlobene kakhulu. Amazinyo ebhakede le-excavator abhekene nezindlela ezihlukile zokuguguleka kunemiphetho yokusika i-bulldozer - ikakhulukazi ngoba izinyo le-excavator lithinta izinto ezivame ukuba nzima futhi ezikhahlameza kakhulu kunezinto ezicindezelwa yi-bulldozer, futhi ngoba izinyo libhekene nokucindezeleka kokushaywa njengoba ibhakede le-excavator limba ebusweni bezinto kunokuba liqhubeke lidlule kulo.
Izinto eziyinhloko okufanele zicatshangelwe ekukhetheni izinyo lebhakede lomgodi wokumba yiphrofayili yezinyo (enquma ikhono lezinyo lokungena ezintweni kanye nendawo yokuguguleka), izinga lezinto zezinyo (enquma ukumelana nokuguguleka kanye nokumelana nokushayisana), kanye nohlelo lokugcina izinyo (okumele luvimbele ukulahlekelwa yizinyo ngenkathi luvumela ukushintshwa kwezinyo okusebenzayo ngesikhathi sokukhiqiza). Ngokuvamile ngincoma izinyo elincane (elingena kalula ezintweni eziqinile) eline-geometry yesihloko esithuthukisa ukungena (njengesihloko esicijile noma se-chisel kunesihloko sebhloko elibanzi) labavukuzi abasebenza emigodini ngezinto eziqinile.
Ukulinganisa Impilo Yokugqoka: Indlela Yokulinganisa Nokuqhathanisa Thola Ukusebenza
Indlela ephumelela kakhulu yokwenza ngcono ukucaciswa kwe-GET ukukala impilo yangempela yokuguguleka kokucushwa kwe-GET yamanje bese uyiqhathanisa nedatha yokulinganisa yezinhlelo zokusebenza ezifanayo. Lokhu kuvumela umphathi wemikhumbi ukuthi abone ukuthi ngabe ukucaciswa kwamanje kusebenza ngaphezu noma ngaphansi kokulindelekile, futhi enze izinqumo ezisekelwe kudatha mayelana nokuthuthukisa noma ukushintsha ibanga le-GET. Ngincoma uhlelo lokulinganisa impilo yokuguguleka oluhlelekile lwazo zonke izinhlelo zokusebenza zemikhumbi yenkali.
Uhlelo lokulinganisa engiluncomayo lulandelela izilinganiso ezilandelayo zesethi ngayinye ye-GET efakwe emshinini ngamunye: usuku lokufakwa namahora okusebenza ekufakweni; izinsuku zokuhlolwa namahora okusebenza ekuhlolweni ngakunye; isisindo sethiphu ekufakweni (silinganiswa esikalini esilinganisiwe ngaphambi kokufakwa); isisindo sethiphu ekuhlolweni ngakunye (silinganiswa ngendlela efanayo); isizathu sokususwa (kugugile, kuphukile, kulahlekile, kushintshiwe okuhleliwe); amahora okusebenza ekususweni; kanye namathani ezinto ezithuthiwe ngesikhathi sokuphila kwesethi ye-GET (kusukela kumarekhodi okukhiqiza). Kusukela kule datha, ama-KPI alandelayo angabalwa: amahora ngesethi yethiphu (isikhathi sokugqoka), amatani ngesethi yethiphu (isikhathi sokugqoka esilungisiwe ngokukhiqiza), izindleko ngehora lokusebenza, kanye nezindleko ngethani lezinto ezithuthiwe. Lawa ma-KPI angaqhathaniswa phakathi kwemishini, phakathi kwezindawo zenkali, phakathi kwezinkathi zonyaka, naphakathi kwamamaki e-GET ukuze kutholakale imininingwane efanele yokusebenza ngakunye.
Ngisebenzise lolu hlelo lokulinganisa amakhasimende amaningana emikhumbi ye-quarry, futhi idatha iveza njalo umehluko omkhulu ekusebenzeni kwe-GET kuyo yonke imikhumbi okungachazwanga umehluko wezinto ezibonakalayo kuphela. Kwesinye isimo, sithole ukuthi i-dozer eyodwa yayifinyelela ngaphansi kwengxenye yempilo yokuguguleka komshini ofanayo osebenza endaweni efanayo ye-quarry, okuyinto ucwaningo oluveze ukuthi ibangelwe ukusethwa kwe-engeli yebhakede okungalungile okwakubangela ukuthi i-GET ikhuhle esikhundleni sokusika impahla. Ukulungisa i-engeli yebhakede (ukulungiswa kwezindleko ezingenalutho) kuthuthukise impilo yokuguguleka kwe-GET ngo-60% futhi kunciphisa izindleko ze-GET ngethani ngo-35% - konke lokhu kusuka ekuthuthukisweni komkhuba wokulungisa okwatholakala kuphela ngokulinganisa impilo yokuguguleka okuhlelekile.
Izindleko Eziphelele Zokuhlaziywa Kobunikazi Bezinqumo Zokucaciswa Kwe-GET
Indlela efanele yokuqhathanisa imininingwane ehlukene ye-GET ukuhlaziywa kwezindleko zobunikazi (i-TCO) eziphelele ezibala zonke izingxenye zezindleko phakathi nesikhathi sokuhlaziya, hhayi nje izindleko zokuqala zezingxenye. Ngincoma ukuhlaziywa kwe-TCO ngezingxenye ezilandelayo, ezibalwa ngesisekelo sokuhanjiswa kwezinto ngethani ngalinye: Izindleko zengxenye ye-GET (kufaka phakathi amathiphu, ama-adaptha, nanoma iyiphi ihadiwe yokugcina); Izindleko zomsebenzi zokushintsha ze-GET (kufaka phakathi izinga lomsebenzi wobuchwepheshe, amahora ngokushintsha ngakunye, kanye nenani lezinguquko ngesikhathi ngasinye); izindleko zesikhathi sokungasebenzi kwemishini (kufaka phakathi ukulahlekelwa kokukhiqiza ngesikhathi sokushintsha kwe-GET, okulinganiselwa emalini engenayo engaphansi ngethani ngalinye lezinto ezithuthiwe); izindleko zomthelela wokukhiqiza (ukusebenza kahle kwe-dozer okuncishisiwe ngesikhathi lapho i-GET igugile kodwa ingakashintshi, okulinganiselwa kusetshenziswa umehluko phakathi kwejika lokusebenza kahle kwe-GET egugile ne-GET entsha); kanye nezindleko zomonakalo wesibili (noma yikuphi ukulungiswa kwesakhiwo se-blade okubangelwa yi-GET egugile, okuncishisiwe phakathi nesikhathi sokuhlaziya).
Ukuhlaziywa kwe-TCO efanele kuvame ukwembula ukuthi incazelo ye-GET ebiza kancane kakhulu empeleni iyona ebiza kakhulu ngokwesisekelo se-TCO, futhi okuphambene nalokho. Kokunye ukuhlaziywa kwe-quarry ye-limestone esebenza ngama-bulldozer angu-4, ngiqhathanise i-GET yensimbi ejwayelekile ephathwa ngokushisa (USD 180 ngesethi yethiphu, impilo yokugqokwa yamahora angu-300) ne-GET ye-premium chrome carbide overlay (USD 380 ngesethi yethiphu, impilo yokugqokwa yamahora angu-550). Izindleko ze-GET eziqondile ngehora kwakungu-USD 0.60 ngokwejwayelekile uma kuqhathaniswa ne-USD 0.69 ye-premium - i-premium yayibiza kakhulu ngokwesisekelo sezindleko eziqondile. Kodwa lapho kufakwa umthelela wokukhiqiza kanye nezindleko zomonakalo wesibili, i-GET ejwayelekile yayine-TCO engu-USD 2.40 ngehora lokusebenza kuyilapho i-premium GET yayine-TCO engu-USD 1.85 ngehora lokusebenza - inzuzo engu-23% ye-TCO yencazelo ye-premium naphezu kwezindleko zayo zokuqala eziphakeme.
