Zofunikira zachilengedwe m'malo omanga nyumba zikukulirakulira.YT28, chifukwa cha kugwirira ntchito bwino kwambiri pobowola pogwiritsa ntchito madzi, imatha kuchepetsa fumbi louluka ndi theka m'malo obisika.

Izi zimapangitsa kuti ikhale yoyenera kumanga metro, ngalande zotulutsira madzi, ndi nyumba zosungiramo zinthu zapansi panthaka komwethanzi la ogwira ntchito komanso mpweya wabwinondi zinthu zofunika kwambiri.

Pogwiritsa ntchito ubwino waukulu wa chilengedwe uwu, YT28kubowola miyala ya pneumaticYapangidwa osati kuti igwire ntchito yokha, komanso kuti malo onse ogwirira ntchito akhale bwino. M'malo ovuta, omwe nthawi zambiri amakhala opanda mpweya wabwino wokwanira pansi pa nthaka, fumbi la silika lomwe limapangidwa ndi mpweya limakhala ndi chiopsezo chachikulu pa thanzi, zomwe zimapangitsa kuti matenda opuma azikhala nthawi yayitali monga silicosis. YT28 imakumana mwachindunji ndi vutoli kudzera mu njira yake yonyowa.kubooladongosolo. Mosiyana ndi kuboola kouma komwe kumachitika nthawi zambiri komwe kumataya tinthu tambiri toopsa mumlengalenga, YT28 imalowetsa madzi olamulidwa mwachindunji kudzera mu chitsulo chobowolera ndi kumaso kwa bit. Njirayi imaphimba fumbi lomwe lili pachomera, ndikutseka tinthu tating'onoting'ono tisanayambe kuuluka. Zotsatira zake ndi kusintha kwakukulu kwa mawonekedwe a ogwiritsa ntchito, kuchepetsa kutopa ndi maso, ndikupanga mpweya wabwino kwambiri kwa ogwira ntchito onse omwe ali pafupi.

Kupatula ntchito yake yayikulu yochepetsera fumbi, njira yobowola yonyowa iyi imapereka maubwino ena ambiri omwe amawonjezera magwiridwe antchito komanso moyo wautali wa zida. Kuyenda kosalekeza kwa madzi kumagwira ntchito ngati choziziritsira chachilengedwe, kumachepetsa kwambiri kutentha kwambiri komwe kumachitika pa nsonga ya bowolo panthawi yolowa. Izi zimachepetsa kupsinjika kwa kutentha kwa bowolo, kuchepetsa kuwonongeka ndikuwonjezera moyo wa ntchito ya zida zomwe zimagwiritsidwa ntchito. Kuphatikiza apo, madziwo amachotsa bwino zidutswa za bowololo kuchokera m'chitsime, kusunga nkhope yoyera yogwirira ntchito yomwe imalola kuti liwiro lolowera liziyenda mwachangu komanso nthawi yobowola igwire bwino ntchito. Opanga ma kontrakitala akupeza kuti ndalama zoyambira mu YT28 zimalipira phindu osati kokha pakuchepetsa zovuta zaumoyo ndi chitetezo komanso kuchepetsa ndalama zogwirira ntchito kwa nthawi yayitali chifukwa cha kuchepa kwa ma bit replacement frequency komanso kuchepa kwa nthawi yogwira ntchito kwa makina.

Malingaliro a kapangidwe ka YT28 amayang'ana kwambiri kudalirika kolimba pansi pa kukakamizidwa. Pistoni yake yolimba komanso njira yabwino yogawa mpweya imawonetsetsa kuti mphamvu zake zikuyenda bwino, zomwe zimathandiza kuti igwire ntchito kudzera mu granite yolimba ndi basalt popanda kugwedezeka. Zinthu zake zoyendetsera bwino, monga zogwirira zochepetsera kugwedezeka ndi kapangidwe koyenera, zimachepetsa kupsinjika kwa wogwiritsa ntchito panthawi yosinthasintha, kuonetsetsa kuti ntchito zambiri zitha kusungidwa popanda kusokoneza chitonthozo cha ogwira ntchito. Pamene zomangamanga zapadziko lonse lapansi zikukankhira pansi pa nthaka mozama komanso malamulo azachilengedwe akulimba, YT28 imayimira ngati mnzawo wotsimikizika. Ndi chida choposa chida; ndi yankho lathunthu la mapulojekiti omwe kupita patsogolo sikungabwere ndi anthu kapena dziko lapansi, mogwirizana bwino ndi zofunikira za uinjiniya wamakono ndi mfundo zomanga zachilengedwe.
