In migodi ya pansi pa nthaka yokhala ndi miyala yolimbaKuchita bwino komanso kukhazikika kwa zinthu kumatsimikizira kupita patsogolo kwa polojekiti.YT29A kubowola miyala ya pneumaticimachita bwino kwambiri m'malo awa chifukwa cha mphamvu zake zolimba komanso kuthandizira kokhazikika kwa miyendo ya mpweya. Pobowola mabowo akuya m'migodi yagolide ndi mitsempha yachitsulo, YT29A imafupikitsa nthawi yobowola ndikuchepetsa ntchito ya compressor.

Ogwira ntchito amayamikira YT29A'smagwiridwe antchito odalirika pansi pa chinyezi chambiri ndi fumbi, zinthu zomwe zimapezeka pansi pa nthaka. Kulimba kwake kumachepetsa nthawi yosamalira, zomwe zimapangitsa kuti ikhale njira yotsika mtengo yogwirira ntchito zopitilira muyeso.

Pomanga maziko olimba awa, YT29A yapangidwa kuti ikhale yolondola komanso yotonthoza kwa wogwiritsa ntchito, zomwe zimapangitsa kuti malo ake azikhala opindulitsa. Dongosolo lake labwino kwambiri la ma valve amkati limapereka kugunda kwamphamvu komanso kokhazikika kwa pistoni, kuonetsetsa kuti imalowa mwachangu ngakhale m'mapangidwe ovuta kwambiri a granite ndi basalt. Izi zimapangitsa kuti pakhale mabowo oyera komanso odziwikiratu, omwe ndi ofunikira kwambiri pakugawikana bwino komanso kuwongolera ma profiles a ngalande. Mpweya wolumikizana umapereka kukhazikika kwapadera, kuchepetsa kutopa kwa wogwiritsa ntchito panthawi yosinthana kwa nthawi yayitali ndikulola kuti mabowo azilumikizana molondola. Kulondola kumeneku kumachepetsa kusweka kwambiri komanso kuwononga mphamvu, zomwe zimathandiza mwachindunji kuti pakhale mitengo yotetezeka komanso yogwira mtima kwambiri.

Kupatula mphamvu yeniyeni, kapangidwe ka chobowoleracho kamayang'ana kwambiri kuthekera kogwirira ntchito. Zigawo zofunika monga chuck ndi piston zimapangidwa kuchokera ku zitsulo zolimba kwambiri kuti zipirire tinthu tating'onoting'ono tomwe timayamwa. Kapangidwe kosavuta komanso kosavuta kamalola ogwira ntchito kuchita kafukufuku wanthawi zonse ndikusintha magawo mwachangu, kuchepetsa nthawi yowononga yogwira ntchito ya makina. Kwa oyang'anira migodi, kudalirika kumeneku ndi phindu lalikulu lazachuma. Kugwiritsa ntchito mpweya pang'ono kwa YT29A sikuti kumangochepetsa ndalama zamagetsi komanso kumalola makina omwe alipo kuti azithandizira zobowolera zingapo nthawi imodzi, zomwe zimapangitsa kuti phindu la ndalama zomwe zagwiritsidwa ntchito pa zomangamanga likhale lalikulu. Mumakampani omwe ola lililonse la ntchito limawerengedwa, YT29A imawoneka kuti ndi yoposa chida chokha - ndi chuma chanzeru chofulumizitsa njira zopititsira patsogolo chitukuko ndikuwonetsetsa kuti mapulojekiti ovuta apansi panthaka akuyenda bwino.
