Joang ho lekola hore na tie-down e na le ntlha e lekaneng ea polokeho?

Tiedowns, tse tsejoang hape e le li-tie-downs kapa tensioners, li sebelisoa haholo liindastering tse kang indasteri, thepa, le kaho ho boloka le ho tsamaisa lintho tse fapaneng. Safety factor ke ea bohlokoa ho nahanoa ha u khetha le ho sebelisa li-tiedowns. Sengoliloeng sena se tla qaqisa mokhoa oa ho lekola hore na tiedown e na le ntlha e lekaneng ea polokeho ho netefatsa polokeho le ts'epo nakong ea ts'ebeliso.

1. Ho utloisisa mohopolo oa ntlha ea polokeho
Safety Factor (SF) ke parameter ea bohlokoa ha ho etsoa le ho lekola li-tiedowns. E bontša karo-karolelano pakeng tsa matla a tiedown tlas'a maemo a tloaelehileng a ho sebetsa le mojaro o moholo oo e hlileng e o jarang.

Ntho e phahameng ea tšireletso e bolela moeli o phahameng oa tšireletso, o ka thibelang molemo ho senya lisebelisoa kapa likotsi tse bakoang ke ho imeloa kelellong kapa maemo a sa lebelloang.

2. Mefuta le maemo a ts'ebeliso ea li-tiedowns
Li-Tiedown li tla ka mefuta e fapaneng, ho kenyeletsoa li-tiedowns, li-automatic tiedowns, le li-tiedown tsa motlakase.

Mefuta e fapaneng ea li-tie-down e loketse maemo a fapaneng a ts'ebeliso. Ka mohlala, li-tie-downs li loketse meroalo e bobebe le libaka tse bonolo tsa ts'ebetso, ha li-tie-down tsa motlakase li loketse meroalo e boima le libaka tse rarahaneng tsa ts'ebetso.

3. Mehato ea ho lekola ntlha ea polokeho ea li-tie-downs
3.1 Etsa qeto ea boima bo lekantsoeng ba tie-down
Mojaro o lekantsoeng oa tie-down o bolela mojaro o moholo oo o ka o mamellang ka mokhoa o sireletsehileng tlas'a maemo a tloaelehileng a ts'ebetso.

Ha u hlahloba ntlha ea tšireletso, u lokela ho qala ka ho utloisisa boima bo lekantsoeng ba tie-down, boo hangata bo ka fumanoang ho leibole ea tie-down kapa buka ea lihlahisoa.

3.2 Utloisisa tikoloho ea mosebetsi le maemo a mojaro
Tšireletseho ea tie-down ha e itšetlehe feela ka matla a eona, empa hape le tikolohong ea tšebeliso le maemo a mojaro. Ka mohlala, sebakeng se nang le mocheso o phahameng kapa mahlaseli a matla a ultraviolet, matla a ho tlama a ka fokotseha. Ka hona, ha ho hlahlojoa ntlha ea tšireletso, sebaka sa sebele sa ho sebetsa le maemo a mojaro a lokela ho nkoa.

3.3 Sheba chebahalo le boemo ba tie-down
Pele o sebelisoa, tie-down e lokela ho hlahlojoa ka mahlo ho netefatsa hore ha ho na tšenyo e totobetseng, ho roala kapa ho senyeha. Tšenyo leha e le efe e bonahalang e ka fokotsa matla a tie-down, kahoo e ama ntlha ea eona ea tšireletso

3.4 Etsa tlhahlobo ea mojaro
Teko ea mojaro ke mokhoa o otlolohileng oa ho lekola ntlha ea polokeho ea tie-down. Ka ho sebelisa mojaro o ntseng o eketseha butle-butle ho tie-down tlas'a maemo a laoloang, ts'ebetso ea ts'ireletso ea eona ts'ebetsong ea sebele e ka khethoa. Teko ea mojaro e lokela ho etsoa tlas'a tataiso ea litsebi le ho latela litekanyetso le melaoana ea polokeho

3.5 Ho buuoa ka litekanyetso le litlhaloso tsa indasteri
Maemo a indasteri le litlhaloso li fana ka tataiso le litšupiso bakeng sa ntlha ea polokeho ea li-tie-down
. Mohlala, tekanyetso ea Europe EN12195 e fana ka litlhokahalo bakeng sa tumellano ea polokeho ea li-tie-downs tse sebelisoang 'marakeng oa Europe. Ha ho hlahlojoa ntlha ea polokeho ea tie-down, litekanyetso tsena le litlhaloso li lokela ho boleloa ho netefatsa hore li fihlela litlhoko tsa indasteri.

4. Mokhoa oa ho bala oa ntlha ea polokeho
Lintlha tsa polokeho li ka baloa ka foromo e latelang:

SF=Ho robeha matla/Moroalo o sebetsang

Moo, matla a ho robeha a bolela boima bo boholo boo tie-down e ka mamellang pele e robeha, 'me mojaro o sebetsang o bolela mojaro oo tie-down e lokelang ho o mamella ha e sebelisoa.

Ka mohlala, haeba matla a ho senya ke lithane tse 10, 'me mojaro oa eona oa ho sebetsa ha e le hantle ke lithane tse 2,5, ntlha ea tšireletso ke:

SF=10/2.5=4
Sena se bolela hore tie-down e na le ntlha ea tšireletso ea makhetlo a 4, ke hore, tlas'a maemo a tloaelehileng a ho sebetsa, matla a eona ke makhetlo a 4 ho feta mojaro oa sebele oo o o jereng.

5. Litlhokomelo le tlhokomelo
Ha u sebelisa tie-down, lintlha tse latelang li lokela ho hlokomeloa:

Sebelisa li-tie-down feela tse sa senyehang
U se ke ua jarisa tie-down
Qoba ho pepesa tie-down ho mocheso o phahameng kapa mahlaseli a matla a ultraviolet
Boloka le ho hlahloba tie-down khafetsa ho netefatsa hore e maemong a matle a ho sebetsa

6. Qetello
Ho lekola ntlha ea polokeho ea tie-down ke ts'ebetso e felletseng e hlokang ho nahanoa ka lintlha tse ngata, ho kenyeletsoa boima bo lekantsoeng ba tie-down, tikoloho ea ho sebetsa, maemo a mojaro, le chebahalo. Tšireletseho le ts'epahalo ea tie-down e ka netefatsoa ka ho latela litekanyetso le litlhaloso tsa indasteri, ho etsa liteko tsa mojaro, le ho etsa tlhokomelo ea kamehla. Tšebelisong ea 'nete, mekhoa e sireletsehileng ea ts'ebetso e lokela ho lateloa kamehla ho thibela likotsi.

Ka selelekela sa sengoloa sena, ho na le tšepo ea hore babali ba tla khona ho utloisisa le ho lekola ntlha ea polokeho ea tie-down, 'me kahoo ba etse liqeto tse bohlale le liqeto mosebetsing oa sebele.
