Mfundo zazikuluzikulu zogwiritsira ntchito Chitetezo cha Kugwa kwa Chitetezo

Zinthu zitatu za Dongosolo la Chitetezo cha Fall: zida zotetezera thupi lonse, zolumikizira, malo opachikika.Zinthu zitatu zonsezi ndi zofunika kwambiri.Zomangira zotetezera thupi lonse zimavalidwa ndi anthu ogwira ntchito motalika, zokhala ndi mphete yooneka ngati D yolendewera pachifuwa kapena kumbuyo.Zida zina zotetezera thupi zimakhala ndi lamba, zomwe zingagwiritsidwe ntchito poyikapo, zida zopachika komanso zoteteza m'chiuno.Zigawo zolumikizira zimaphatikizapo zinyalala zachitetezo, zinyalala zotetezedwa zokhala ndi chotchinga, chotsekereza kugwa kosiyana ndi zina. Zimagwiritsidwa ntchito kulumikiza zingwe zachitetezo ndi popachikikapo.Kukhazikika kwake kumakhala kokulirapo kuposa 15KN.Malo opachika ndi gawo lamphamvu la dongosolo lonse lachitetezo cha kugwa, komwe kugwedezeka kokhazikika kuyenera kukhala kwakukulu kuposa 15KN.Muyenera kutsatira katswiri posankha popachikika.

Munthawi yogwiritsira ntchito chitetezo cha kugwa, ndikofunikira kuwunika kugwa.Fall factor = kutalika kwa kugwa / kutalika kwa lanyard.Ngati kugwa kuli kofanana ndi 0 (mwachitsanzo, wogwira ntchito akukoka chingwe pansi pa malo olumikizirana) kapena osachepera 1, ndipo ufulu woyenda ndi wosakwana mamita 0,6, zida zoyikira ndizokwanira.Njira zodzitetezera kugwa ziyenera kugwiritsidwa ntchito nthawi zina pomwe kugwa kumakhala kwakukulu kuposa 1 kapena komwe kumayenda kwaufulu kuli kwakukulu.Zomwe zikugwa zikuwonetsanso kuti njira yonse yotetezera kugwa ndi yolendewera kwambiri komanso yotsika.

Momwe mungagwiritsire ntchito bwino chingwe chachitetezo?

(1) Mangani chingwe.Zigawo zomangira m'chiuno ziyenera kumangidwa mwamphamvu komanso moyenera;

(2) Pogwira ntchito yoyimitsidwa, musapachike mbedza mwachindunji pazitsulo zotetezera, zipachike ku mphete pazitsulo zotetezera;

(3) Musapachike chingwe chotetezera ku chigawo chomwe sichili cholimba kapena ndi ngodya yakuthwa;

(4) Osasintha zigawo nokha mukamagwiritsa ntchito mtundu womwewo wa zida zotetezera;

(5) Musapitirize kugwiritsa ntchito chingwe chotetezera chomwe chakhudzidwa kwambiri, ngakhale maonekedwe ake sasintha;

(6) Osagwiritsa ntchito chingwe chotetezera podutsa zinthu zolemera;

(7) Chingwe chachitetezo chiyenera kupachikidwa pamalo olimba apamwamba.Kutalika kwake sikutsika kuposa m'chiuno.

Zomangira zotetezera ziyenera kumangirizidwa pomanga pathanthwe lalitali kapena malo otsetsereka opanda zida zodzitetezera.Iyenera kupachikidwa m'mwamba ndikugwiritsidwa ntchito pamunsi ndipo kugundana kogwedezeka kuyenera kupewedwa.Apo ayi, ngati kugwa kugwa, mphamvu yowonongeka idzawonjezeka, motero ngozi idzachitika.Utali wa lanyard wotetezedwa ndi malire mkati mwa 1.5 ~ 2.0 metres.Chotchinga chiyenera kuwonjezeredwa mukamagwiritsa ntchito lanyard wautali wotetezedwa womwe ndi wopitilira mamita atatu.Musamangirire zingwe zotetezera ndikupachika mbedza pa mphete yolumikizira m'malo moipachika pazitetezo zachitetezo mwachindunji.Zomwe zili pa lamba wachitetezo sizidzachotsedwa mwachisawawa.Chingwe chachitetezo chiyenera kuyang'aniridwa bwino pakatha zaka ziwiri chikugwiritsidwa ntchito.Musanapachikidwa pamiyendo yachitetezo, kuyezetsa kwake kuyenera kuchitidwa, ndi kulemera kwa 100 kg poyesa dontho.Ngati pali kuwonongeka pambuyo pa kuyesedwa, zikutanthauza kuti gulu lachitetezo litha kupitiliza kugwiritsidwa ntchito.Miyendo yomwe imagwiritsidwa ntchito pafupipafupi iyenera kuyang'aniridwa pafupipafupi.Ngati pali vuto linalake, chingwecho chiyenera kuchotsedwa pasadakhale.Chingwe chatsopano chachitetezo sichingagwiritsidwe ntchito pokhapokha ngati pali satifiketi yowunikira zinthu.

Pofuna kuonetsetsa chitetezo cha ogwira ntchito m'mlengalenga pakuyenda kwawo, makamaka pa ntchito yowopsa kwambiri, anthu ayenera kumangirira zida zonse zodzitetezera kugwa ndikupachika pa lanyard.Osagwiritsa ntchito chingwe cha hemp kupanga lanyard yotetezeka.Chingwe chimodzi chachitetezo sichingagwiritsidwe ntchito ndi anthu awiri nthawi imodzi.
