Ungahlola kanjani ukuthi i-tie-down inesici sokuphepha esanele?

Tiedowns, owaziwa nangokuthi ama-tie-downs noma ama-tensioners, asetshenziswa kakhulu ezimbonini ezifana nezimboni, ezokuthutha, nezokwakha ukuze kuvikelwe futhi kuthuthwe izinto ezihlukahlukene. Isici sokuphepha siwukucatshangelwa okubalulekile lapho ukhetha futhi usebenzisa ama-tiedowns. Lesi sihloko sizochaza kabanzi ukuthi ingahlolwa kanjani ukuthi i-tiedown inento eyanele yokuphepha ukuze kuqinisekiswe ukuphepha nokwethembeka ngesikhathi sokusetshenziswa.

1. Ukuqonda umqondo wesici sokuphepha
I-Safety Factor (SF) iyipharamitha ebalulekile lapho uklama futhi uhlola i-tiedowns. Ibonisa isilinganiso phakathi kwamandla e-tiedown ngaphansi kwezimo ezivamile zokusebenza kanye nomthwalo omkhulu owuthwalayo ngempela.

Isici sokuphepha esiphezulu sisho umkhawulo wokuphepha ophezulu, ongavimbela kangcono ukulimala kwemishini noma izingozi ezibangelwa ukugcwala ngokweqile noma izimo ezingalindelekile.

2. Izinhlobo nezimo zohlelo lokusebenza lwe-tiedowns
Ama-Tiedowns eza ngezinhlobo ezahlukahlukene, okuhlanganisa ukubopha okwenziwa ngesandla, ukubopha okuzenzakalelayo, nokubopha ngogesi.

Izinhlobo ezihlukene zokubopha zifanele izimo zohlelo lokusebenza ezahlukene. Isibonelo, ukubopha okwenziwa ngesandla kulungele imithwalo elula kanye nezindawo zokusebenza ezilula, kuyilapho ukubopha kukagesi kulungele imithwalo esindayo kanye nezindawo zokusebenza eziyinkimbinkimbi.

3. Izinyathelo zokuhlola isici sokuphepha se-tie-downs
3.1 Nquma umthwalo olinganiselwe wokubophela phansi
Umthwalo olinganiselwe we-tie-down ubhekisela kumthwalo omkhulu ongamelana nawo ngokuphephile ngaphansi kwezimo zokusebenza ezivamile.

Lapho uhlola isici sokuphepha, okokuqala udinga ukuqonda umthwalo olinganiselwe we-tie-down, ovame ukutholakala kulebula yokubopha phansi noma imanuwali yomkhiqizo.

3.2 Qonda indawo yokusebenza nezimo zomthwalo
Isici sokuphepha se-tie-down asixhomekile emandleni ayo kuphela, kodwa futhi endaweni yokusetshenziswa kanye nezimo zomthwalo. Isibonelo, endaweni enezinga lokushisa eliphezulu noma imisebe ye-ultraviolet enamandla, amandla okubopha angancipha. Ngakho-ke, lapho kuhlolwa isici sokuphepha, indawo yokusebenza yangempela kanye nezimo zomthwalo zidinga ukucatshangelwa.

3.3 Hlola ukubukeka nesimo sokubopha
Ngaphambi kokusetshenziswa, i-tie-down kufanele ihlolwe ngokubonakalayo ukuze kuqinisekiswe ukuthi akukho monakalo osobala, ukugqoka noma ukuguqulwa. Noma yimuphi umonakalo obonakalayo unganciphisa amandla okubopha, ngaleyo ndlela uthinte isici sayo sokuphepha

3.4 Yenza ukuhlola umthamo
Ukuhlolwa komthwalo kuyindlela eqondile yokuhlola isici sokuphepha sokubopha phansi. Ngokusebenzisa umthwalo okhuphuka kancane kancane ekubopheni ngaphansi kwezimo ezilawulwayo, ukusebenza kwayo kokuphepha ekusetshenzisweni kwangempela kunganqunywa. Ukuhlolwa komthwalo kufanele kwenziwe ngaphansi kokuqondisa kochwepheshe futhi ngokuhambisana namazinga nemithethonqubo efanele yokuphepha

3.5 Ukubhekiselwa kumazinga emboni kanye nokucaciswayo
Izindinganiso zomkhakha kanye nokucaciswa kunikeza isiqondiso nereferensi yesici sokuphepha se-tie-downs
. Isibonelo, izinga lase-Europe i-EN12195 lihlinzeka ngezimfuneko zokuthobela ukuphepha kwezibopho (tie-downs) ezisetshenziswa emakethe yaseYurophu. Lapho kuhlolwa isici sokuphepha sokubopha, lawa mazinga kanye nokucaciswa kufanele kubhekiselwe kuwo ukuze kuqinisekiswe ukuthi ahlangabezana nezidingo zemboni.

4. Indlela yokubala yesici sokuphepha
Isici sokuphepha singabalwa ngefomula elandelayo:

SF=Ukuphulwa kwamandla/umthwalo osebenzayo

Lapho, amandla okugqekeza asho umthwalo omkhulu i-tie-down engamelana nawo ngaphambi kokwephuka, futhi umthwalo osebenzayo ubhekisela emthwalweni okudingeka ukuthi i-tie-down ime nawo uma isetshenziswa.

Isibonelo, uma amandla okunqamula i-tie-down angamathani ayi-10, futhi umthwalo wawo wokusebenza osetshenziswayo ungamathani angama-2.5, isici sayo sokuphepha sithi:

SF=10/2.5=4
Lokhu kusho ukuthi i-tie-down inesici sokuphepha izikhathi ezingu-4, okungukuthi, ngaphansi kwezimo ezijwayelekile zokusebenza, amandla ayo aphindwe izikhathi ezingu-4 kunomthwalo wangempela owuthwalayo.

5. Izinyathelo zokuqapha nokunakekela
Lapho usebenzisa i-tie-down, amaphuzu alandelayo kufanele futhi aqashelwe:

Sebenzisa kuphela ama-tie-downs angonakalisiwe
Ungalayishi kakhulu i-tie-down
Gwema ukuveza i-tie-down emazingeni okushisa aphezulu noma emisebeni enamandla ye-ultraviolet
Gcina futhi uhlole i-tie-down njalo ukuze uqinisekise ukuthi isesimweni esihle sokusebenza

6. Isiphetho
Ukuhlola isici sokuphepha sokubophela phansi kuyinqubo ebanzi edinga ukucatshangelwa kwezinto eziningi, okuhlanganisa umthwalo olinganiselwe wokuboshelwa phansi, indawo yokusebenza, izimo zomthwalo, nokubukeka. Ukuphepha nokuthembeka kokubopha kungaqinisekiswa ngokulandela izindinganiso zomkhakha kanye nokucaciswa, ukwenza izivivinyo zomthwalo, kanye nokwenza ukunakekelwa okujwayelekile. Ekusetshenzisweni kwangempela, izinqubo zokusebenza eziphephile kufanele zihlale zilandelwa ukuvimbela izingozi.

Ngesethulo salesi sihloko, kwethenjwa ukuthi abafundi bazokwazi ukuqonda kangcono futhi bahlole isici sokuphepha sokubopha, futhi ngaleyo ndlela benze ukukhetha okuhlakaniphile nezinqumo emsebenzini wangempela.
