Kampani yogulitsa zida zomangira yomwe yakhala ikupereka mayankho a makina omangira kwa zaka 30.
Kugula makina odulira ang'onoang'ono aku China kungakhale njira yanzeru, koma pokhapokha mutayang'ana makinawo ngati mainjiniya, osati ngati munthu amene akufufuza pamtengo wotsika kwambiri pakati pausiku. Msikawu ndi waukulu mokwanira kuti uyenera kuganiziridwa mozama. Malinga ndi Lipoti la msika wa Market Research Future la mini-embarkers , msika wapadziko lonse wa mini-excavator unali ndi mtengo wa USD 8.26 biliyoni mu 2024 ndipo akuyembekezeka kufika USD 15.82 biliyoni pofika chaka cha 2035. Mu Chingerezi chosavuta, anthu ambiri akugula makina awa, ndipo si onse omwe akugula mwanzeru.
China nayonso ndi gawo lalikulu la chithunzi cha zinthu zomwe zilipo. Zambiri zamalonda za Banki Yapadziko Lonse ya WITS za HS 842952 zikusonyeza kuti United States idatumiza mayunitsi 110,573 mu gulu la zofukula izi mu 2024, kuphatikiza mayunitsi 29,353 ochokera ku China . Izi sizikutanthauza kuti chofukula chilichonse chaching'ono cha ku China ndi chabwino, ndipo sizikutanthauza kuti makina onse otsika mtengo ndi oipa. Zimatanthauza kuti ogula amafunika mndandanda woyenera asanalipire ndalama zomwe adasungitsa.
Cholakwika choyamba ndi kuyerekeza makina ndi mtengo wokha. Mini excavator si chinthu chimodzi chokhazikika. Caterpillar imafotokoza zofukula zazing'ono monga makina kuyambira pa tani imodzi mpaka matani 10 , okhala ndi mphamvu zonyamulira kuyambira pafupifupi 1,000 lb pa ma micro models mpaka kupitirira 5,000 lb pa ma tani akuluakulu 8-10. Imeneyo ndi njira yaikulu. Makina a m'munda ndi makina odulira matope onse angatchedwe "mini excavators," koma samakhala moyo womwewo.
Musanapemphe mtengo wabwino kwambiri, fotokozani ntchitoyo. Kodi muyenera kukumba mozama bwanji? Kodi makinawo adzakhala ndi chotsukira, chotsukira, chotsukira kapena choduladula? Kodi adzagwira ntchito pa nthaka yofewa, zipata zolimba, malo otsetsereka kapena ntchito zobwereka komwe ogwira ntchito angaigwiritse ntchito mofewa ngati ngolo yogulira zinthu? Ntchitoyo ikangomveka bwino, kukula kwa makinawo kumayamba kumveka bwino.
Kabuku ka wogulitsa kayenera kukupatsani manambala oyezeka, osati mawu ofotokozera okha. Kuti mupeze muyezo wothandiza, Tsamba la tsatanetsatane wa Cat 301.8 ili ndi mphamvu ya 21 hp , kulemera kwa ntchito kwa 2,029 kg , kuya kwa kukumba kwa 2,570 mm , kuyenda kwa pampu ya 66 L/min ndi kuthamanga kwa zida za 245 bar . Chofukula chaching'ono cha ku China chomwe chili mu kalasi yomweyo ya 1.8-2 ton sichifunika kukopera manambala amenewo ndendende, koma wogulitsayo ayenera kupereka deta yamtundu womwewo.
| Chinthu Chabwino | Zoyenera Kufunsa | Chifukwa Chake Ndi Chofunika |
|---|---|---|
| Kulemera kwa ntchito | Kulemera konse kwa makina okhala ndi njanji, mafuta ndi denga/kabati | Kukhazikika, kulemera kwa mayendedwe ndi mphamvu yokumba zimadalira izi |
| Injini | Mtundu, chitsanzo, mphamvu ya ukonde ndi muyezo wa mpweya woipa | Kusamveka bwino kwa injini kungayambitse mavuto pa ntchito ndi kasitomu |
| Dongosolo la hayidiroliki | Kuyenda kwa pampu, kuyenda kothandizira ndi kupanikizika | Zomangira zimafuna kuyenda koyenera, osati mapini olondola okha |
| Malo okumba | Kumba kuya, kufikira ndi kutalika kwa thanki | Zimaletsa kugula makina omwe sangathe kufika kuntchito |
| Chidebe chapansi pa galimoto | M'lifupi mwa track, ma roller, ma sprockets ndi tsatanetsatane wa drive yomaliza | Dera ili nthawi zambiri limapanga ndalama zokwera mtengo zokonzera |
| Chithandizo cha zigawo | Zosefera, mapaipi, zisindikizo, ma rollers ndi ma mota | Makina otsika mtengo si otsika mtengo ngati zida zimatenga miyezi iwiri |
Ngati wogulitsa apewa manambala awa, chepetsani liwiro. Wopanga weniweni kapena wogulitsa kunja sayenera kufunikira masiku atatu kuti apeze kulemera kwa makina ake.
Injini imakopa chidwi chifukwa ogula amazindikira mayina a makampani. Ndi zoona, koma makina a hydraulic amasankha momwe makinawo amamvera. Mini excavator yokhala ndi hydraulic yosayenera ingawoneke bwino pazithunzi koma ikumvabe ulesi pamalopo. Boom ikhoza kunyamuka pang'onopang'ono, mkono ungazengereze, kapena chomangira chingagwire ntchito ngati kuti chadya nkhomaliro yayitali.
Mukayang'ana mini excavator yaku China, yerekezerani mphamvu ya injini, kuyenda kwa pampu, kuthamanga ndi mphamvu yoziziritsira pamodzi. Ngati mukufuna kugwiritsa ntchito breaker kapena auger, funsani kuti mudziwe kuchuluka kwa madzi ndi kuthamanga kwa madzi, kenako yerekezerani manambalawo ndi zofunikira zomangirira. Chizindikiro cha Cat 301.8 cha kuyenda kwa pampu ya 66 L/min ndi kuthamanga kwa 245 bar chimapatsa ogula malo ofunikira a kalasi iyi ya makina. Popanda deta ya kuyenda ndi kuthamanga kwa madzi, simukuyerekeza makina kwenikweni; mukuyerekeza mitundu ya utoto.
Pachitseko chapansi pa galimoto ndi pomwe makina ambiri "otsika mtengo" amakhala okwera mtengo pang'onopang'ono. chitsogozo cha galimoto yosungiramo zinthu zakale kuti mavuto okhudzana ndi galimoto yoyendera pansi pa galimoto akhoza kuimira ndalama zoposa theka la ndalama zokonzera zokumba . Chiwerengero chimenecho chokha ndi chifukwa chokwanira choyang'anira bwino ma track, ma rollers, ma sprockets ndi ma final drives asanatumizidwe.
Pemphani zithunzi zapafupi ndi kanema woyenda. Ma track ayenera kukhala molunjika, ma roller sayenera kuwonetsa kutuluka kwa madzi, ndipo ma drive omaliza ayenera kukhala ouma makina akatentha. Ngati makina ali ndi chidebe chokulirapo, yesani malo onse awiri. Ayenera kutsetsereka bwino popanda kumangirira. Ngati akuyenda ngati kabati yodzaza dzimbiri, ganizirani momwe adzachitire pakatha miyezi isanu ndi umodzi m'matope.
Kuwotcherera bwino sikuti ndi kokha mkanda wabwino. Kumatanthauza kusinthasintha kwa madera omwe ali ndi kupsinjika: phazi la boom, cholumikizira cha mkono, chomangira tsamba, cholumikizira chozungulira ndi chimango cha track. Yang'anani ngati pali chodulidwa chocheperako, ma porosity, kukula kosagwirizana kwa weld ndi kupukutira kokayikitsa. Utoto watsopano ungapangitse ntchito yovuta kuoneka yokongola kwakanthawi, koma kugwedezeka kumakhala ndi chizolowezi choipa chowulula zinsinsi.
Kapangidwe ka chitetezo kamafunikanso umboni, osati mawu olembedwa. Cat 301.8 imalemba miyezo monga ROPS ISO 12117-2:2008 , TOPS ISO 12117:1997 ndi Top Guard ISO 10262:1998 Level I pa mfundo za malonda ake. Ngati wogulitsa akunena kuti kanyumba kameneka ndi "kotetezeka," funsani muyezo womwe kakukwaniritsa. Pamisika yotumiza kunja, miyezo yotchulidwayo ndi yofunika kwambiri kuposa mawu odalirika.
Kutsatira malamulo si nkhani yaying'ono yokhudza kayendetsedwe ka ntchito. Pa makina a dizilo opita ku US, Malamulo a US EPA okhudza injini ya dizilo ya zida zolemera Zimaphimba zida zomwe sizili pamsewu monga ma stowers, ndipo EPA imati dizilo ya sulfure yotsika kwambiri ili ndi kuchuluka kwa sulfure kokwanira 15 ppm . Ogula ayenera kuyang'ana chizindikiro cha injini, satifiketi ya EPA ndi invoice asanatumizidwe, osati makinawo akafika pa kasitomu.
Kwa ogula a ku EU, mphamvu ya injini ndi kutsata malamulo a Stage V ndizofunikira. Malamulo a EU 2016/1628 imakhazikitsa malire a utsi wa injini za makina oyenda omwe si a pamsewu, kuphatikizapo mphamvu zodziwika bwino zofukula. Ngati wogulitsa sangathe kufotokoza ngati injiniyo ikutsatira malamulo a EPA, CE kapena Stage V, si "nkhani yaying'ono yokhudza mapepala." Izi zingakhudze kuchotsedwa kwa katundu wa pa kasitomu, mtengo wogulitsanso, komanso chidaliro cha makasitomala.
Kuwunika koyenera musanatumize makina kuyenera kuwonetsa kuti makina akugwira ntchito, osati kungoyima. Pemphani kanema wokhudza kuyamba kozizira, kungokhala chete, kusuntha mwamphamvu, kukweza mphamvu, kuyenda kwa mkono, kupindika kwa chidebe, kugwedezeka, kugwira ntchito kwa tsamba, kuyenda mbali zonse ziwiri komanso kugwira ntchito yothandizira yamadzimadzi. Kuyenda kwa mphindi ziwiri ndi nyimbo zosangalatsa kumbuyo si mayeso. Ndi mpikisano wokongola wa makina.
| Malo Oyesera | Kodi Zotsatira Zabwino Zimawoneka Bwanji? |
|---|---|
| Kuyamba kozizira | Imayamba popanda utsi wambiri kapena kugwedezeka mobwerezabwereza |
| Ma Hydraulics | Kuyenda bwino kwa boom, mkono ndi chidebe popanda kugwedezeka |
| Dongosolo lozungulira | Amatembenukira mbali zonse ziwiri osagogoda kapena kuchedwa |
| Njira yoyendera | Njira zolunjika popanda kuphwanya kapena kulumpha |
| Ma drive omaliza | Mafuta satuluka mutatha kuthamanga kotentha |
| Dongosolo lamagetsi | Zowonetsera, magetsi, zochapira ndi zotchingira chitetezo zimagwira ntchito |
| Zikalata | Manambala a seri, chizindikiro cha injini, invoice ndi mndandanda wofanana wa zonyamula |
Chofukula chaching'ono chabwino kwambiri cha ku China sichimakhala chotsika mtengo nthawi zonse. Ndi makina okhala ndi zofunikira zomveka bwino, ma hydraulic ofanana, pansi pa galimoto yolimba, zikalata zotsatirika ndi zida zina zomwe mungagule pambuyo pake. Mtengo ndi wofunika, ndithudi. Palibe amene amasangalala kulipira ndalama zowonjezera pongokongoletsa. Koma mtengo uyenera kukuthandizani kusankha pakati pa makina oyenerera, osati kusintha mawonekedwe.
Ngati wogulitsa apereka tsatanetsatane, makanema enieni oyesera, zikalata zotsatizana ndi malamulo ndi chithandizo cha zida, chofukula chaching'ono chochokera ku China chingakhale chida chothandiza kwa makontrakitala, okonza malo, minda ndi magulu obwereketsa. Ngati wogulitsa apewa manambala, asintha mitundu ya injini popanda chidziwitso, kapena sangathe kufotokoza kayendedwe ka madzi, chokani. Dothi ndi loleza mtima. Lidzakhala likudikirabe mukapeza makina oyenera.
