Zvinhu zvitatu zveFall Dziviriro system: yakazara-yemuviri kuchengetedza harness, yekubatanidza zvikamu, mapoinzi ekurembera.Zvinhu zvitatu zvose zvinokosha.Hanzu dzekuchengetedza muviri dzakakwana dzakapfekwa nevanhu vanoshanda muhurefu, dzine mhete yakaita D yekurembera pamberi pechipfuva kana kumashure.Zvimwe zvekuchengetedza muviri zvine bhandi, rinogona kushandiswa kuisa, kuturika maturusi uye kudzivirira chiuno.Zvikamu zvekubatanidza zvinosanganisira machira ekuchengetedza, machira ekuchengetedza ane buffer, differential fall arrester etc. Inoshandiswa kubatanidza machira ekuchengetedza uye nzvimbo yekurembera.Its static tension yakakura kupfuura 15KN.Kurembera nzvimbo ndiyo nzvimbo yekumanikidza yeseti yekudonha yekudzivirira system, iyo static tension inofanirwa kunge yakakura kupfuura 15KN.Zviri nani utevere munhu ane hunyanzvi pakusarudza nzvimbo yekurembera.
Muchiitiko chekushandiswa kwekuwa kwekudzivirira system, zvinodikanwa kuti uongorore kudonha chinhu.Fall factor = kureba kwekuwa/ lanyard kureba.Kana iyo yekudonha yakaenzana ne0 (semuenzaniso mushandi anodhonza tambo pasi penzvimbo yekubatanidza) kana isingasviki 1, uye rusununguko rwekufamba rwuri pasi pe 0.6 metres, midziyo yekuisa inokwana.Masisitimu ekudzivirira ekuwa anofanirwa kushandiswa mune dzimwe nguva uko kudonha kwechinhu chikuru kupfuura 1 kana uko dhigirii rerusununguko rwekufamba rakakura.Iyo yekudonha chinhu inoratidza zvakare kuti iyo yese yekudonha yekudzivirira system ndeye yakakwira kurembera uye yakaderera kushandiswa.
Nzira yekushandisa sei kuchengetedza harness nenzira kwayo?
(1) Simbisa tambo.The chiuno buckle zvikamu zvinofanira kusungwa zvakasimba uye zvakarurama;

(3) Usarembedza tambo dzekuchengetedza kune chimwe chinhu chisina kusimba kana nekona yakapinza;
(4) Usachinja zvinhu uri woga paunenge uchishandisa mhando imwe chete yetambo dzekuchengetedza;
(5) Usarambe uchishandisa tambo yekuchengetedza iyo yakakanganiswa zvakanyanya, kunyangwe chimiro chayo chisingachinji;
(6) Usashandise tambo yekudzivirira kupfuudza zvinhu zvinorema;
(7) Hari yezvokuchengetedza inofanira kuturikwa panzvimbo yakakwirira yakasimba.Kureba kwayo hakusi kuderera kupfuura chiuno.
Iyo tambo yekudzivirira inofanirwa kusungirirwa kana uchiita basa rekuvaka mumawere akakwirira kana materu pasina zvidziviriro.Inofanira kusungirirwa kumusoro uye kushandiswa panzvimbo yakaderera uye kudhumhana kunofanira kudzivirirwa.Zvikasadaro, kana kudonha kukaitika, simba rekuita rinowedzerwa, saka njodzi ichaitika.Kureba kwekuchengetedza lanyard kunogumira mukati me1.5 ~ 2.0 metres.Buffer inofanira kuwedzerwa kana uchishandisa lanyard refu yekuchengetedza iyo inodarika mamita matatu.Usapfundo mitsara yekudzivirira uye urembedza hoko parin'i yekubatanidza pane kuti uiturike panzira dzekuchengetedza zvakananga.Zvikamu zviri pabhandi rekuchengetedza hazvizobviswe zvisina tsarukano.Iyo yekuchengetedza harness inofanira kuongororwa zvakakwana mushure memakore maviri ekushandiswa.Usati warembedza lanyard dzekuchengetedza bvunzo dzekukanganisa dzinofanirwa kuitwa, nehuremu hwe100 kg hwekudonha bvunzo.Kana paine kuparadza mushure mekuyedzwa, zvinoreva kuti batch rekuchengetedza harness rinogona kuramba richishandiswa.Mishonga inoshandiswa kakawanda inofanira kuongororwa nguva nenguva.Kana pane chimwe chinhu chisina kujairika, harness inofanira kubviswa pachine nguva.Hani itsva yekuchengetedza haigone kushandiswa chete kana paine chitupa chekuongorora chinoenderana negwaro.
Kuti ive nechokwadi chekuchengetedzwa kwevashandi vemuchadenga panguva yekufamba kwavo, kunyanya kune basa rinoshamisa rine njodzi, vanhu vanofanirwa kusungirira midziyo yekudzivirira yekudonha uye kusungirira pane yakachengeteka lanyard.Usashandise tambo yehemp kugadzira lanyard yekuchengetedza.Lanyard imwe yekuchengetedza haigone kushandiswa nevanhu vaviri panguva imwe chete.
