Vanodonha vanosungazvakakosha midziyo yekuchengetedza inoshandiswa mumaindasitiri akasiyana-siyana kudzivirira vashandi kubva pakudonha uye kukuvara kunogona kuitika.Kunzwisisa mashandiro anoita munhu anosungisa kudonha kwakakosha pakuona kushandiswa kwayo nemazvo uye kudzivirira kwakasimba kwetsaona.Muchinyorwa chino, tichanyatso tarisisa mashandiro anoita vasungwa vekudonha, zvikamu zvavo, uye basa ravo mukudzivirira vanhu vanoshanda pakakwirira.
Mashandisiro anoita iyo anti-fall kifaa:
Basa guru remusungwa wekuwa nderokudzivirira vashandi kubva pakudonha pavanongoerekana vaburuka.Zvisungo zvekudonha zvakagadzirirwa kumisa uye kuvhara tambo yehupenyu kana anchorage point kana yadonha, nekudaro kudzivirira kumwe kudonha nemushandi.Nheyo yekushanda kwemusungwa wekudonha inobva pakushandiswa kwekugadzirisa mabhureki, iyo inobata mararamiro uye inosunga kuwa.
Zvikamu zvakakosha zve fall arrester:
1. Mutsara wehupenyu: Mutsara wehupenyu chikamu chinokosha chekudonha kwekudzivirira.Ndiyo nzira yekutanga yekubatanidza vashandi kune anchor mapoinzi kana zvimiro.Nzira dzehupenyu dzinowanzo gadzirwa nepamusoro-simba zvinhu, zvakadai setambo yekugadzira, tambo yesimbi, kana webhu, uye inofanira kukwanisa kukurira masimba ekudonha.
2. Magetsi emagetsi: Muzvirongwa zvakawanda zvekudzivirira kwekuwa, magetsi anopinza akabatanidzwa mumutsara wehupenyu.Magetsi anomwisa akagadzirirwa kuendesa uye kutora simba rekudonha, kuderedza maitiro kune vashandi uye anchor point.Ichi chikamu chinoita basa rakakosha mukuderedza njodzi yekukuvara muchiitiko chekudonha.
3. Braking mechanism: Iyo braking mechanism ndiyo chikamu chakakosha chekudzivirira kudonha.Yakagadzirirwa kushandura uye kuvhara mutsara wehupenyu muchiitiko chekudonha, kudzivirira mushandi kubva pakudonha mberi.Iyo braking mechanism inofanirwa kuve yakavimbika uye inokwanisa kuita nekukurumidza kumisa kudonha pachinhambwe chakachengeteka.
4. Anchor Point: An anchor point ndiyo dhizaini kana chigadziro icho chinosungirirwa system yekudonha.Inofanirwa kukwanisa kutsigira masimba ekudonha uye kuiswa panzvimbo yekupa yakachengeteka uye yakachengeteka yekubatanidza kune mutsara wehupenyu.
Basa revasungwa vanodonha mukuchengetedza kwevashandi:
Vanosunga vanodonha vanoita basa rakakosha mukuona kuchengetedzwa kwevanhu vanoshanda pakakwirira.Nekumisa zvinobudirira kudonha kuri kuitika, zvishandiso izvi zvinobatsira kudzivirira kukuvara kwakakomba uye kufa kunogona kuguma nekudonha.Vanodonha vanobata basa kuti vape yakavimbika, inokurumidza kupindura kune chiitiko chekudonha, ichipa vashandi chivimbo chekuita mabasa pakukwirira uku vachideredza njodzi.
Izvo zvakakosha kuti uzive kuti vabati vanodonha vanongori chikamu chimwe cheiyo yakazara yekuwa kudzivirira system.Kana ichishandiswa pamwe chete nemamwe matanho ekuchengetedza senge maguardrails, midziyo yekudzivirira uye kudzidziswa kwakakodzera, vanosunga vanodonha vanopa kune yakasarudzika nzira yekudzikisa njodzi dzekudonha munzvimbo yebasa.
Zvinhu zvekucherekedza pakusarudza uye kushandisa yekudonha yekusunga:
Paunenge uchisarudza chibatiso chekudonha chechimwe chishandiso, zvinhu zvakati wandei zvinofanirwa kutariswa kuti ive nechokwadi chekukodzera uye kushanda kwayo.Zvinhu izvi zvinosanganisira nzvimbo yebasa, rudzi rwebasa riri kuitwa, chinhambwe chinogona kudonha, uye huremu hwemushandi.Pamusoro pezvo, nhungamiro yemugadziri yekumisikidza, kuongorora, uye kugadzirisa kweanobatisa kudonha kunofanirwa kuteverwa kuti ive nechokwadi chekushanda kwakaringana.
Kudzidziswa kwakakodzera mukushandiswa kwezvibatiso zvekudonha kwakakoshawo kune vashandi vanofanirwa kushandisa zvisungo zvekudonha.Kunzwisisa nzira yekupfeka nemazvo uye kugadzirisa zvibatiso zvekudonha, kubatanidza mitsara yehupenyu, uye kuita nzira dzekuzvinunura pachiitiko chekudonha kwakakosha kuti uwedzere kuchengetedzwa kwezvishandiso izvi.
Muchidimbu, musimboti wekushanda weafall arresterinotenderera nekukwanisa kukurumidza uye zvinobudirira kumisa kudonha kunoenderera, nekudaro kudzivirira kukuvara kwakakomba uye rufu.Nekunzwisisa zvikamu uye kushanda kwevanosunga vanodonha, vashandirwi nevashandi vanogona kuita sarudzo dzine ruzivo nezve kusarudzwa, kushandiswa nekuchengetedza kwevanosungwa.Kana yakabatanidzwa muchirongwa chekudzivirira kudonha, vanosunga vanodonha vanobatsira kugadzira nzvimbo yakachengeteka yekushanda kune avo vanoshanda pakakwirira.
