Amathrekhi we-mini excavator angcono kakhulu wokusimama? 

Ake sinqamule i-marketing fluff. Uma sikhuluma ngezinto ezisimeme ze-undercarriage, ikakhulukazi amathrekhi emishini ehlangene, akukhona nje ngenjoloba egaywe kabusha. Ibhalansi yokuphila isikhathi eside, izindleko eziphelele zobunikazi, kanye nomthelela womhlaba wangempela wokushintshwa nokulungiswa okumbalwa. Ama-opharetha amaningi alungisa amanani angaphambili, kodwa ukukhetha okuzinzile kuvame ukukhokha ngokuhlala isikhathi eside nokusebenza ngokuhlanza esizeni.

I-Rubber vs. Steel Debate AyinaMnyama Nokumhlophe

Uzozwa okuningi mayelana namathrekhi enjoloba ukuthi inketho 'eluhlaza'. Futhi ezinsizeni eziningi - cabanga ukwakheka kwezwe, umsebenzi wokusiza ezindaweni ezigandayiwe - zinjalo. Banciphisa umonakalo ongaphezulu, bagijima kancane, futhi ngokuvamile babe ne-carbon footprint ephansi kwezokuthutha ngenxa yesisindo. Kodwa ukusimama kuba mnyama uma ibhande lenjoloba lihluleka ngaphambi kwesikhathi emsebenzini oxubile, odinga ukushintshwa okugcwele. Ngike ngabona imishini enamathrekhi enjoloba agugile ngemva kwamahora angu-800 nje ngenxa yokuthi yayisetshenziswa ekugcwaliseni amatshe, umsebenzi ofaneleka kangcono umshini olandelwa insimbi. Impahla esimeme kakhulu yileyo efana nomjikelezo oyinhloko womsebenzi womshini.

Kulapho amathrekhi enjoloba ayingxube noma aqinisiwe angena khona. Abanye abakhiqizi baluka nge-Kevlar noma izintambo zensimbi eziqine kakhulu. Lezi akuzona izixazululo eziyisimangaliso, kodwa zelula impilo ezimeni ezilimazayo. Okubalulekile wukwakhiwa kwangaphakathi kwebhande. Ithrekhi eshibhile ingase isebenzise intambo ye-polyester elula, enganwebeka futhi yehlise izinga ngokushesha ngaphansi kokushuba okuphezulu noma ukushisa. Ukuphumelela okusimeme lapha kubambezela leso sikhathi sokuphela kwempilo, sisuka, sithi, amahora ayi-1,200 siye kwayi-1,800 ngaphambi kokuba kudingeke esikhundleni.

Kumathrekhi ensimbi, impikiswano yokusimama izungeza ukwakhiwa kabusha. Isistimu yethrekhi evaliwe futhi egcotshisiwe (SALT), enezihlahla eziqinile nezikhonkwane, ingabuye yakhiwe kabusha izikhathi eziningi. Awulahli umhlangano wonke; ushintsha izingxenye zokugqoka. Lokhu kudinga isiko lokunakekela elihlelekile, izingubo eziningi ezincane ezingenakho, kodwa amandla okulondoloza izinsiza abalulekile. Ngikhumbula usonkontileka eqhuba i-Takeuchi TB216 enenqola yensimbi eyakhiwe kabusha amahora angaphezu kuka-5,000 kumaphrojekthi amathathu amakhulu. Lezo zinto ezimbalwa zokusetshenziswa ezisetshenziswa empilweni yomshini.

Ubude besikhathi buyi-Ultimate Metric for Sustainability

Khohlwa amalebula angacacile ‘eco-friendly’. Isici esisodwa esikhulu sendawo yemvelo yethrekhi impilo yayo yesevisi. Ithrekhi ehlala isikhathi eside ngo-50% inciphisa imithelela yokukhiqiza, ukuthumela, kanye nokulahlwa kokushintshwa kwayo cishe phakathi. Yilapho idumela lomkhiqizo kanye nemininingwane yobuchwepheshe kubalulekile. Bheka abakhiqizi bethrekhi abashicilela idatha yokumelana nokuhuqwa okuhlanganisiwe (njengemiphumela yokuhlolwa ye-DIN 53516) noma baqinisekise amaphesenti aphezulu wezinto ezisele ngemva kwenombolo emisiwe yamahora.

Sizame ithrekhi yerabha yohlobo lwebhajethi ku-Bobcat E35 eminyakeni embalwa edlule, sihehwa intengo. Inhlanganisela yayithambile kakhulu. Ezimweni eziyisihlabathi, ukugqokwa kwakushesha ngendlela emangalisayo. Sishise ama-lugs ngaphansi kwamahora angama-600. Akukhona nje kuphela ukulahlekelwa ngokwezimali, kodwa futhi kwadingeka silahle leso sidumbu bese senza futhi sithumele esisha—okuwumphumela ongemuhle kuyo yonke imikhakha yokusimama. Isifundo besibiza: izindleko zangempela zihlanganisa ukwehluleka kwemvelo.

Abanye abahlinzeki abacabanga phambili manje sebenikezela ngezinhlelo zokukhiqiza kabusha noma zokushintshisana ezibalulekile zamathrekhi agugile, afana nemboni yebhethri. Le modeli yomnotho oyindilinga iyathembisa kodwa isafufusa. Idinga uchungechunge lwezokuthutha oluqinile ukuze iqoqe futhi icubungule amathrekhi amadala. Izinkampani ezitshala imali kulokhu, njengabanye ochwepheshe bezimoto zangaphansi zaseYurophu, kufanele zilandelwe. Isusa ukugxila ekuthengiseni umkhiqizo kuye ekunikezeni isevisi eqinile.

Ukwehluleka Kwangempela Komhlaba kanye Nalokho Ezisifundisayo

Ukusimama akulona itiyori. Ibonakala odakeni nasedwaleni lendawo yomsebenzi. Iphuzu elilodwa elivamile lokwehluleka okubulala impilo yethrekhi ngaphambi kwesikhathi ukushuba okungafanele. Kokubili i-tension ngokweqile kanye ne-under-tension kudala ukushisa kwangaphakathi okudlulele nokuguga okusheshayo. Ngivule ama-track roller lapho amafutha ayephekwe ngokuphelele ngoba amathrekhi abeqina kakhulu. Lokho kushisa kwehlisa inhlanganisela yenjoloba noma konakala izixhumanisi zensimbi ngaphambi kwesikhathi. Ukuqeqeshwa komsebenzisi ekuhloleni okulula kwansuku zonke kuyingxenye enkulu, evame ukunganakwa, yochungechunge lokusimama.

Enye imininingwane idizayini ye-track pad. Ngamathrekhi enjoloba, iphethini ye-lug ayiyona nje eyokudonsa. Iphethini eklanywe kahle, enama-engeli amaningi ingasabalalisa ingcindezi ngokulinganayo kulo lonke ibhande, ivimbele ukuqhekeka ngaphambi kwesikhathi esisekelweni samalugi. Kumathrekhi ensimbi, ububanzi bephedi bubalulekile. Iphedi ebanzi ku-excavator encane ingase inikeze ukuntanta okungcono endaweni ethambile, yehlise umfutho ophansi kanye nokusetshenziswa kukaphethiloli njengoba umshini usebenza kahle kakhulu. Yilezi zinketho zobunjiniyela ezihlukene ezihlukanisa umkhiqizo ohlala isikhathi eside nolahlwayo.

Iqhaza Labakhi kanye Nochungechunge Lokuhlinzeka Ngomhlaba Wonke

Lokhu kungiletha kubakhiqizi abangene shi emiseleni yokukhiqiza nohwebo lomhlaba wonke. Thatha I-Shandong Pioneer Engineering Machinery Co., Ltd njengesibonelo. Sebekulesi sikhala kusukela ngo-2004, futhi ukuthuthela kwabo esikhungweni esisha ngo-2023 kukhombisa ukukhuphuka kwamandla okukhiqiza. Kungani lokhu kubalulekile ngokusimama? Isikali, uma senziwe kahle, singaholela ekulawuleni inqubo engcono kanye nokutshalwa kwezimali ku-R&D ukuze uthole izinto ezihlala isikhathi eside. Inkampani enombono wesikhathi eside, ethumela ezimakethe ezifunwa kakhulu njenge-US, Canada, neJalimane, kufanele ihlangabezane namazinga aphezulu okuqina ukuze iphile. Iwebhusayithi yabo, https://www.sdpioneer.com, ibonisa ububanzi bawo, futhi ngokubuka kwami, umkhawulo wabo wokuncintisana ngokuvamile ulele ekunikezeni i-spec elinganisiwe—hhayi eshibhe kakhulu, kodwa eyakhelwe ukuhlala emakethe yokuthekelisa. Lokho kuqondaniswa kokusinda kwezohwebo nempilo ende yomkhiqizo yilapho umkhuba oqhubekayo uvame ukuvela khona ngempela.

I-global supply chain abasebenza ngaphakathi kwayo iyisici sokusimama. Ukuhlanganisa ukuthunyelwa kwamathrekhi nezingxenye zenqola yangaphansi ukuya emazweni amaningi kusebenza kahle kakhulu kunokuhlelwa okuhlukene, kweqoqo elincane. Inkampani efana ne-Pioneer, esebenza njengomkhiqizi (ngokusebenzisa i-Hexin) kanye nochwepheshe bezohwebo, ingathuthukisa lokhu kugeleza, inciphise izindleko zeyunithi ngayinye yekhabhoni yokuthutha. Kuyimininingwane engemuva kwesigcawu, kepha iyangeza.

Ngakho-ke, Yini Eyenza Ithrekhi Iphumelele Ukusimama?

Akuwona umkhiqizo owodwa. Kuyalingana. I best mini excavator amathrekhi ngokusebenza okusimeme yilezo ezicaciswe kahle ngomsebenzi, ezivela kumkhiqizi ozibophezele ekuqineni (okufakazelwa yizinto ezicaciswayo nokuhlolwa), agcinwe ngokucophelela esizeni, futhi ekugcineni athathwe ochungechungeni lokunikezela olubiza ukuphila isikhathi eside ngaphezu kokulahlwayo. Kuwuchungechunge lwezinqumo ezinomthwalo wemfanelo.

I-takeway yami ephathekayo? Ngaphambi kokuthenga, cela impilo yesevisi elindelwe yethrekhi ezimeni zakho zokusebenza ezithile. Kubhale phansi uma ukwazi. Hlola okubalulekile kwentambo yangaphakathi ukuze uthole amathrekhi enjoloba. Ngensimbi, buza ngamakhithi okwakha kabusha kanye nengxenye efanayo. Futhi cabangela izindleko eziphelele zobunikazi phakathi neminyaka emithathu, hhayi inani le-invoyisi kusasa.

Ekugcineni, ithrekhi esimeme kakhulu yileyo okungadingeki uyishintshe kaningi. Ihlala emshinini, yenza umsebenzi wayo ngokuchitha isikhathi esincane nokumosha. Lona umgomo wangempela-ukugcina izinsiza zisetshenziswa futhi zingekho egcekeni le-scrap yard inqobo nje uma ubunjiniyela nokunakekelwa okufanele kuvumela. Konke okunye kuwumsindo nje.
