Kampani yogulitsa zida zomangira yomwe yakhala ikupereka mayankho a makina omangira kwa zaka 30.
Yerekezerani ma dump ang'onoang'ono oyendetsedwa ndi mawilo a matope, malo otsetsereka ndi malo opapatiza. Onani momwe kuthamanga kwa nthaka, katundu wonyamula, liwiro ndi kukonza kumakhudzira chisankho chanu.
Kusankha pakati pa chodulira chaching'ono chotsatiridwa ndi choyendetsedwa ndi mawilo kuyenera kuyamba ndi njira yomwe makinawo adzayendera, osati ndi pepala loyamba lofotokozera lomwe limagwera mu imelo yanu. Mawilo amafalitsa kulemera kwa makinawo pamalo akuluakulu olumikizirana, zomwe zimachepetsa kumira pansi pofewa kapena ponyowa. Mawilo nthawi zambiri amagubuduzika momasuka pamalo olimba ndipo amakhala ndi zinthu zochepa zoyendetsera pansi pa galimoto. Komabe, palibe kapangidwe kake komwe kamapereka katundu wambiri, thupi lopapatiza kwambiri kapena mtengo wotsika kwambiri wogwirira ntchito.
Makina abwino ndi omwe amatsiriza maulendo ofunikira otetezeka komanso odzaza mokwanira pamalo anu enieni. Chodulira chotsata njira chingapitirize kugwira ntchito pamene matope akusintha njira yolumikizira mawilo kukhala ntchito yobwezeretsa. Pa konkire yosalala, chodulira chotsata njira chothamangitsidwa chingathe kumaliza maulendo ambiri pomwe chitsanzo chotsata njiracho chikubwererabe pamalo otsitsira. Mikhalidwe ya malo nthawi zambiri imathetsa mkangano mwachangu kuposa kabuku kogulitsa.

Ma track amatha kuchepetsa kuthamanga kwa nthaka, koma chiwerengero chothandiza ndi kuthamanga kwa makinawo ndi makina odzaza mokwanira. Yanmar yalemba zake C08-A Power tracked dumper pa 0.20 kg/cm² ikatsitsidwa ndi 0.48 kg/cm² ikatsitsidwa . Mtundu wodziyikira wokha umawonjezeka kuchoka pa 0.23 kufika pa 0.52 kg/cm². M'zochitika zonse ziwiri, kuwonjezera katundu wogwira ntchito kumachulukitsa kuwirikiza kawiri mphamvu yofalitsidwa.
Izi ndizofunikira chifukwa chodulira chopanda kanthu chomwe chimatsata chingadutse udzu popanda kusiya umboni wambiri, pomwe makina omwewo okhala ndi skip yonse angapereke zotsatira zosiyana kwambiri. C08 imanyamulanso mpaka 800 kg ndipo imagwiritsa ntchito njanji za 180 mm m'lifupi, zomwe zikusonyeza chifukwa chake katundu wonyamula, malo olumikizirana ndi nthaka ziyenera kuganiziridwa pamodzi.
Mawilo amaika katunduyo m'magawo ang'onoang'ono olumikizirana ndi matayala, koma nthawi zina izi sizimakhala zovuta. Pa nthaka yolimba, amatha kuchepetsa kukana kugwedezeka ndikufupikitsa gawo loyenda la kuzungulira kulikonse. Mwachitsanzo, Muck-Truck imafalitsa mphamvu yonyamula katundu yolemera makilogalamu 250, m'lifupi mwake 710 mm ndi liwiro lalikulu la pafupifupi 5.6 km/h pa imodzi mwa mawilo ake ang'onoang'ono otayira matayala. Ziwerengerozi sizikuyimira chiwiya chilichonse chotayira matayala, koma zimafotokoza chifukwa chake barrow yopepuka imatha kugwira ntchito bwino pamisewu yokonzedwa kapena yopapatiza.
Chodulira chaching'ono chotsatiridwa nthawi zambiri chimakhala malo otetezeka oyambira pamene matayala amatha kumira, kutsetsereka kapena kutaya chiwongolero. Malo olumikizirana nthawi yayitali amagawa katunduyo ndipo amathandiza makinawo kuti asakhudze nthaka yosagwirizana. Ngakhale zili choncho, ogula ayenera kuyerekeza kuthamanga kwa nthaka yodzazidwa, kukula kwa njanji ndi malo otsetsereka. Ma track a rabara ndi othandiza, koma si makapeti amatsenga.
The Chodulira chaching'ono chotsatiridwa cha ACE HDCX-600 imaphatikiza katundu wolemera makilogalamu 600 wokhala ndi maulendo awiri komanso kutalika kwa nsonga yayitali pafupifupi mamita 1.45. Kutalikako kotsitsa katundu kungakhale kothandiza pamene zinthu ziyenera kulowetsedwa mwachindunji mu skip, trailer kapena chidebe chokwezedwa. Ikhoza kuchotsa gawo lowonjezera logwirira ntchito, ngakhale skip iyenera kukhala yotsika pamene makina akuyenda. Katundu wokwezedwa ndi nthaka yosalinganika nthawi zambiri sizikhala mabwenzi abwino.
Chotsukira chosungiramo zinthu chogwiritsidwa ntchito pokonza malo chingathandize kuchepetsa ming'alu pa nthaka yonyowa, bola ngati wogwiritsa ntchitoyo apewa kuzungulira kozungulira komwe kumakanda pamwamba. Kukula kwa makina nakonso n'kofunika, koma sikufotokoza nkhani yonse yolowera.
Wacker Neuson adalemba mndandanda wake wazinthu zomwe zikubwera. DT08 tracked dumper pa mulifupi wa 790 mm , ndi katundu wapamwamba kwambiri wa 800 kg komanso liwiro lalikulu la 4 km/h. Wopangayo amafalitsanso kuwerengera kwa 36% ndi malo apamwamba kwambiri otsetsereka a madigiri 20. Malire awa amagwira ntchito pa chitsanzo chimenecho ndipo sayenera kukopedwa ku makina ena, makamaka pamene skip yakwezedwa kapena kukwezedwa.
Zipangizo zina zingasinthenso momwe makinawo amachitira zinthu m'malo otsekedwa. Yanmar C08 yokhazikika ndi 810 mm mulifupi ndi pafupifupi 1,930 mm kutalika, pomwe mtundu wodziyikira wokha ndi 835 mm mulifupi ndi pafupifupi 2,595 mm kutalika. Chonyamuliracho chimawonjezera 25 mm m'lifupi koma pafupifupi 665 mm kutalika. Mwanjira ina, makinawo angadutse pachipata kenako nkupeza kuti ngodya yomwe ili kumbuyo kwake ili ndi mapulani ena.
Chotayira choyendetsedwa ndi mawilo cha malo omangira athyathyathya chimakhala chokongola pamene njirayo ndi yolimba, yayitali komanso yopanda mipata yozama. Chitsanzo chopepuka cha Muck-Truck chimalemera pafupifupi 135 kg chikatsitsidwa ndipo chimayenda mpaka 5.6 km/h. Poyerekeza, DT08 yotsatiridwa ili ndi kulemera kogwirira ntchito kwa 595–710 kg ndi liwiro lalikulu la 4 km/h.
Iyi si njira yoyesera magwiridwe antchito mwachindunji chifukwa makinawa ali ndi katundu wosiyanasiyana komanso mapangidwe osiyanasiyana. Izi zikusonyeza chifukwa chake kulemera kwa katundu ndi liwiro loyendera ziyenera kuyerekezeredwa pamodzi ndi mphamvu yonyamulira katundu. Makina akuluakulu amatha kusuntha zinthu zambiri paulendo uliwonse, pomwe makina ang'onoang'ono amatha kukhala osavuta kunyamula, kunyamula ndi kutembenuza.
Kuyerekeza mphamvu ya katundu wa dumper kuyenera kuphatikizapo nthawi yozungulira:
Kutulutsa zinthu pa ola limodzi = katundu wolipidwa paulendo × maulendo omalizidwa pa ola limodzi
Taganizirani chitsanzo chongoyerekeza. Chodulira cholemera makilogalamu 600 chomwe chimatha kusuntha katatu chimasuntha makilogalamu 1,800 pa ola limodzi. Chodulira cholemera makilogalamu 250 chomwe chimatha kusuntha katatu chimasuntha makilogalamu 2,000. Panjira yolimba imeneyo, makina ang'onoang'ono okhala ndi mawilo amasuntha zinthu zambiri pang'ono. Komabe, ngati matope achepetsa kufika pa magawo atatu, mphamvu yake imatsika kufika pa makilogalamu 750 pa ola limodzi.
| Chitsanzo chongoganizira | Malipiro | Mizere yomaliza | Zotuluka zowerengedwa |
|---|---|---|---|
| Chodulira chotsata malo pamalo oyenera | makilogalamu 600 | 3 | 1,800 kg/h |
| Chotayira chozungulira chozungulira chili panjira yolimba | makilogalamu 250 | 8 | 2,000 kg/h |
| Chotayira chozungulira choyendetsedwa ndi mawilo chimachedwa ndi matope | makilogalamu 250 | 3 | 750 kg/h |
Kuwerengera si kuyesa kwa munda. Kumangosonyeza chifukwa chake katundu wonyamula katundu ndi liwiro lapamwamba siziyenera kuweruzidwa padera. Nthawi yoyika katundu, nthawi yoperekera, kutalika kwa njira, malo ozungulira ndi nthawi yodikira pa mgodi wonse wamagetsi zonse ziyenera kuwerengedwa mofanana.
Chidebe choyendetsedwa ndi anthu chomwe chimayikidwa ndi njira zoyendera za rabara, ma sprockets, ma rollers ndi makina otsekereza. Matope odzaza ayenera kuchotsedwa, kufufuzidwa kwa mphamvu ya njirayo ndikuyang'aniridwa kuti aone ngati pali mabala kapena kulimbitsa komwe kwawonekera. Kuzungulira mobwerezabwereza pa konkire wokhuthala kungapangitsenso kuti kuwonongeke kwambiri, kotero chodulira choyendetsedwa ndi anthu chomwe chimayikidwa ndi njira yocheperako sichiyenera kugwiritsidwa ntchito ngati mpando wa ofesi wozungulira.
Chodulira choyendetsedwa ndi mawilo chimapewa zinthu zambiri zomwe zili pansi pa galimoto, koma matayala amatha kuboola, kutaya mphamvu kapena kuwonongeka mosiyana. Mabearing, unyolo, ma axles, mabuleki ndi zida zoyendetsera galimoto zimafunabe chisamaliro. Palibe chiwerengero chodalirika chomwe chikusonyeza kuti mawilo nthawi zonse amakhala otsika mtengo kusamalira. Kupezeka kwa zida zakomweko, zizolowezi za wogwiritsa ntchito, maola ogwirira ntchito ndi momwe zinthu zilili pamwamba nthawi zambiri zimakhala zofunika kuposa chizindikiro chosavuta cha ma track-versus-wheels.
Sankhani chodulira chaching'ono chotsatiridwa pamene nthaka yofewa, njira zosalinganika, malo otsetsereka komanso kugwiritsa ntchito panja nthawi zonse zimakhala zofunikira kwambiri. Sankhani chodulira chaching'ono choyendetsedwa ndi mawilo pamene njirayo ndi yolimba, mtunda woyenda ndi wautali ndipo kukonza matayala mosavuta n'kofunika. Pa chodulira chaching'ono cha malo opapatiza , yesani njira yonse osati khomo lolowera lokha.
Musanayitanitse, yerekezerani kuthamanga kwa pansi komwe kwadzaza, katundu wolipidwa, m'lifupi mwake, kutalika kwa makina, liwiro loyenda, kukwera kwake, kutalika kwa pansi, kutalika kwa kutsika kwa mtunda ndi mwayi wopeza chithandizo. Makina oyenera ndi omwe amamaliza kuzungulira kofunikira popanda kukhazikika, kuwononga pamwamba kapena kupanga nthawi yosafunikira yopuma.
Magalimoto oyendetsedwa ndi ma tracked nthawi zambiri amakhala oyenera nthaka yofewa, yamatope komanso yosalinganika. Magalimoto oyendetsedwa ndi mawilo amatha kukhala othandiza kwambiri panjira zolimba pomwe liwiro loyenda komanso kulemera kochepa kwa mayendedwe kumachepetsa nthawi yoyendera.
Ayi. Kulemera kumadalira chassis, injini, ma hydraulic, mabuleki ndi kapangidwe ka skip. Ma tracks amathandiza kuti galimoto igwirizane ndi nthaka, koma sapanga mphamvu zonyamulira zokha.
Chodulira chotsata njira yoyendetsera galimoto chingathe kutsitsa mphamvu ya pansi, ngakhale kuti kuzungulira mwamphamvu kungasokoneze udzu. Makina opepuka okhala ndi mawilo ang'onoang'ono angayambitse kuwonongeka kochepa pansi pouma komanso kolimba, kotero kulemera kolemera ndi njira yoyendetsera galimoto zonse ziwiri ndizofunikira.
Makina okhala ndi mawilo nthawi zambiri amakhala ndi zinthu zochepa zogwirira ntchito pansi pa galimoto. Makina otsatiridwa amatha kuperekabe mtengo wotsika wogwirira ntchito pamalo ovuta pamene kugwira ntchito kwawo kumalepheretsa kuchedwa, ntchito yobwezeretsa zinthu komanso kusokonezeka kwa kayendedwe ka magalimoto.
