Ndi kudzicheka mawotchi kutseka kwenikweni, palibe wapadera reaming kubowola chofunika.
Ndiosavuta kuyiyika, yodalirika pamachitidwe, ndipo imatha kupirira ikazunguliridwa molunjika.
Mukakulungidwa ku torque yoyika, chitetezo cha nangula chimatsimikizika pamene kuya kwa maliro sikukwanira.
Mphamvu yamphamvu komanso yotsutsa-dun imatha kukwaniritsa zofunikira pansi pa katundu wanthawi yayitali, cyclic katundu ndi chivomerezi.
Range Yoyenera:
1. Kukonza mapaipi osiyanasiyana ndi mabulaketi a chingwe mu milatho, njanji, tunnel ndi subways.
2. Chitetezo ndi kukonza zida zazikulu monga zopangira mafakitale, ma crane, ndi malo opangira magetsi a nyukiliya.
3. Kuyika ndi kukonza mapaipi osiyanasiyana m'nyumba za anthu monga madzi ndi magetsi ndi mapaipi amoto.
4. Kulumikizana ndi kukonza zothandizira zosiyanasiyana monga mapangidwe otchuka a adyo khoma ndi kapangidwe kachitsulo.
5. Kuyika ndi kukonza matabwa otchingira mawu ndi zopinga zina.
6. Kuyika zitseko zoletsa kuba, zitseko zozimitsa moto, ndi mazenera akuba mafuta.

3. Ndikoyenera kukonza pamakona osiyanasiyana, kuphatikizapo kumbuyo, ndipo ndi yoyenera pamphepete mwaling'ono ndi kuikapo malo ang'onoang'ono.
4. Palibe pafupifupi kupsyinjika kwapadziko lonse komwe kumakulirakulira m'chilengedwe, komwe kungakwaniritse zofunikira zakuya kosiyanasiyana kwa maliro.
5. Mapangidwe aukadaulo, asayansi komanso okhwima amatsimikizira chitetezo, kukhazikika ndi mphamvu zolimba za kupanga kristalo Kokani mphamvu ndi kukameta ubweya.
6. Poyerekeza ndi anangula ena wamba, m'mimba mwake wa dzenje lobowola ndi laling'ono, koma ali ndi mphamvu zolimba, kukana kutopa,Anti-seismic performance, yotetezeka komanso yodalirika.
7. Pali chizindikiro chakuya chodziwikiratu pa bolt ya nangula, yomwe ndi yabwino kuyika.
8. Malingana ndi malo osiyanasiyana ogwiritsira ntchito, pali zipangizo zosiyanasiyana ndi zosiyana zotsutsana ndi kutu, zomwe zingathe kukwaniritsa zosowa za makasitomala.zosowa za ogwiritsa ntchito.
