Mu dziko la migodi, zomangamanga, ndi kukumba miyala, komwe kudalirika nthawi zambiri kumaposa zovuta zamakono, gulu linalake la zida zopumira limapitilizabe kukhala msana wa ntchito za tsiku ndi tsiku.YT28, YT27ndiYT29Amndandanda wa ma drill a pneumatic leg rock, pamodzi ndiTPB40, TPB60ndiTPB90Zipangizo zodulira miyala, zikuyimira zaka zambiri za ntchito yodziwika bwino m'malo ovuta kwambiri. Zida izi sizokhudza ukadaulo wowala; ndizokhudza kumaliza ntchito, kusinthana nthawi ndi nthawi, m'malo omwe angalepheretse zida zolimba.

 

Mabowole a miyala a YT-series amapangidwira cholinga chimodzi chachikulu: kuswa bwino pakati ndi miyala yolimba. Malingaliro awo a kapangidwe kake amayang'ana kwambiri mphamvu ya pistoni, kugwira ntchito molunjika ndi miyendo ya mpweya, komanso zosowa zochepa zosamalira. Mpweya wosinthika umapereka mphamvu yodyetsa yokhazikika komanso chithandizo chofunikira cha wogwiritsa ntchito, zomwe zimathandiza kubowola molondola m'njira zosiyanasiyana. YT28 nthawi zambiri imakhala yofunika kwambiri pakugwira ntchito bwino komanso kugwira ntchito bwino, pomwe YT29A imakhala ndi mphamvu zambiri pakupanga zinthu zovuta komanso zopweteka kwambiri. Kugwirizana kwawo kumatanthauza kuti zida zotsalira ndi chidziwitso chogwira ntchito zimatha kusamutsidwa, zomwe zimachepetsa kwambiri nthawi yopuma komanso ndalama zophunzitsira. M'malo akutali kapena mapulojekiti omanga ngalande komwe makina ovuta a hydraulic amalephera, mabowolewa a pneumatic amapitiliza kugwira ntchito, mawu awo apadera a rhythmic akuwonetsa kupita patsogolo kosalekeza.

 

Zipangizo zazikuluzikulu zobowola izi ndi TPB mndandanda wa zophulitsa miyala zolemera. Mitundu ya TPB40, TPB60, ndi TPB90 imapanga mzere wathunthu wa ntchito zophwanyira, kugwetsa, ndi kuyika ngalande. TPB40, monga chida chapakati, imapereka mphamvu yabwino komanso kuthekera koyendetsa bwino pothyola slabs za konkire kapena kuchotsa zinthu zolemera. TPB60 imagwira ntchito zovuta kwambiri monga kuthyola miyala ikuluikulu kapena nthaka yozizira, pomwe TPB90 imagwira ntchito ngati malo enieni amphamvu, okhoza kuthyola miyala ikuluikulu yomwe ndi yayikulu kwambiri kwa zophwanyira miyala zoyamba. Njira yachiwiri yophwanyira miyala, yomwe nthawi zambiri imatchedwa "popcorning," ndiyofunikira kwambiri kuti zinthu ziyende bwino kuchokera pamwamba pa mgodi kupita ku fakitale yokonzera.

 

Kugwirizana pakati pa ma drill a YT ndi ma TPB breakers kumapanga njira yogwirira ntchito yogwira mtima kwambiri komanso yodziyimira payokha. Choyamba, ma drill a YT amapanga mabowo ophulika kapena ma drill okhazikika bwino kuti agawikane. Pambuyo pophulika kapena kuchotsa koyamba, miyala ndi miyala yayikulu kwambiri yomwe imachokera imadulidwa bwino pamalopo pogwiritsa ntchito ma TPB breakers. Izi zimachotsa zopinga, zimachepetsa kufunika kophulika koyamba mobwerezabwereza, komanso zimapangitsa kuti magalimoto onyamula katundu aziyenda. Kukongola kwa dongosololi kuli mu kuphweka kwake komanso zomangamanga zogawana. Mitundu yonse iwiri ya zida imagwira ntchito pa mpweya wabwino wa mafakitale, zomwe zikutanthauza kuti compressor imodzi, yamphamvu imatha kuthandizira gulu lonse la ma drill ndi ma breakers.

 

Kwa oyang'anira mapulojekiti ndi oyang'anira malo, dongosololi limapereka kusinthasintha kosayerekezeka kwa magwiridwe antchito komanso kuwongolera ndalama. Kusavuta kwa makina a zida izi kumalola kukonza ndi kukonza pamalopo, kupewa kudikira kwa nthawi yayitali kwa akatswiri apadera. Kuphatikiza apo, kulimba kwawo ndi kodziwika bwino; sizachilendo kupeza ma YT drills ndi ma TPB breakers akadali kugwira ntchito pambuyo pa zaka makumi ambiri akugwiritsidwa ntchito molimbika. Mumakampani omwe akuyang'ana kwambiri pa mtengo wonse wa umwini, mbiri yotsimikizika, komanso kudalirika kwa zida izi zoyendera mpweya kumaonetsetsa kuti zimakhalabe gawo lofunikira kwambiri padziko lonse lapansi la migodi ndi zomangamanga, zomwe zimagwira ntchito zomwe zimayimira maziko enieni a chitukuko cha zomangamanga.
