Zofunikira zoyambirira za chingwe chachitetezo

Chingwe chachitetezo ndi zida zoteteza kuti ogwira ntchito asagwere pamwamba.Chifukwa kutalika kwa kugwa kumakulirakulira.Choncho, chingwe chachitetezo chiyenera kukwaniritsa zinthu ziwiri zotsatirazi:

(1) Iyenera kukhala ndi mphamvu zokwanira kunyamula mphamvu pamene thupi la munthu likugwa;

Chingwe chachitetezo (2) chingalepheretse thupi la munthu kugwa mpaka malire omwe angayambitse kuvulala (ndiko kuti, liyenera kunyamula thupi la munthu lisanafike malire awa, ndipo silidzagwanso).Izi ziyenera kufotokozedwanso.Thupi la munthu likagwa kuchokera pamtunda, ngati lidutsa malire ena, ngakhale thupi la munthu litakokedwa ndi chingwe, mphamvu yomwe imalandira ndi yaikulu kwambiri, ndipo ziwalo zamkati za thupi la munthu zidzawonongeka ndi kufa. .Choncho, kutalika kwa chingwe sikuyenera kukhala motalika kwambiri, ndipo payenera kukhala malire.

Pankhani ya mphamvu, zingwe zotetezera nthawi zambiri zimakhala ndi zizindikiro ziwiri za mphamvu, zomwe ndi mphamvu zolimba komanso mphamvu zogwira ntchito.Muyezo wa dziko umafuna kuti mphamvu zolimba (mphamvu yomaliza) ya malamba a mipando ndi zingwe zake ziyenera kukhala zazikulu kuposa mphamvu ya nthawi yayitali yomwe imayambitsidwa ndi kulemera kwa munthu kugwa.

Mphamvu zokhuza zimafunikira mphamvu yakukhudzidwa kwa zingwe zotetezera ndi zowonjezera, zomwe ziyenera kupirira mphamvu yobwera chifukwa cha kugwa kwa thupi la munthu.Nthawi zambiri, mphamvu yamphamvu imatsimikiziridwa ndi kulemera kwa munthu amene wagwayo ndi mtunda wogwa (ie mtunda wokhudzidwa), ndipo mtunda wakugwa umagwirizana kwambiri ndi kutalika kwa chingwe chachitetezo.Kutalikira kwa lanyard, kumapangitsanso kutalika kwa mtunda komanso mphamvu yamphamvu.Chiphunzitso chimatsimikizira kuti thupi la munthu lidzavulazidwa ngati litakhudzidwa ndi 900kg.Choncho, poonetsetsa kuti ntchitoyo ikuchitika, kutalika kwa chingwe chachitetezo kuyenera kukhala kwaufupi kwambiri.

Malinga ndi muyezo wadziko lonse, kutalika kwa chingwe chachitetezo kumayikidwa pa 0.5-3m malinga ndi ntchito zosiyanasiyana.Ngati lamba wachitetezo atayimitsidwa pamalo okwera kwambiri ndipo kutalika kwa chingwe ndi 3m, mphamvu ya 84kg idzafika ku 6.

Chingwe chachitetezo chiyenera kufufuzidwa musanagwiritse ntchito.Siyani kugwiritsa ntchito ngati yawonongeka.Mukavala, chojambula chosunthika chiyenera kumangidwa, ndipo sichiyenera kukhudzana ndi lawi lotseguka kapena mankhwala.
