Endabeni yokuthuthwa kwemithwalo esindayo, kungaba lula kakhulu ukuvikela impahla ngamaketanga okubopha agunyazwe ngokwezinga le-EN 12195-3, esikhundleni sezintambo zewebhu ezigunyazwe ngokuya nge-EN 12195-2 standard. Lokhu kungukukhawulela inani lemivimbo edingekayo, ngoba amaketanga okushaya ahlinzeka ngamandla okuvikela aphezulu kunama-web lashings.
Isibonelo se-chain lashings ngokuya nge-EN 12195-3 ejwayelekile
Imvamisa amaketanga aqhumayo awohlobo lwesixhumanisi esifushane. Emaphethelweni kukhona izingwegwe noma izindandatho ezithile okufanele zilungiswe emotweni, noma ukuxhuma umthwalo uma kwenzeka ukuqhuma okuqondile.
Lashing Chains ahlinzekwa nge tensioning device. Lokhu kungaba yingxenye engaguquki yeketango lokuqhuqha noma ithuluzi elihlukile elihlanganiswe neketango lokuqhunyiswa ukuze liqiniswe. Kunezinhlobo ezahlukene zamasistimu okuqinisa amandla, njengohlobo lwe-ratchet kanye nohlobo lwe-turn buckle. Ukuze uhambisane nezinga le-EN 12195-3, kuyadingeka ukuthi kube nezisetshenziswa ezikwazi ukuvimbela ukuxega ngesikhathi sokuthutha. Lokhu empeleni kuzobeka engcupheni ukusebenza kahle kokubopha. Ukususwa kwe-post tensioning clearance kumele futhi kukhawulelwe ku-150 mm, ukuze kugwenywe ukuthi kube khona ukunyakaza komthwalo okuholela ekulahlekelweni kwe-tension ngenxa yokuhlalisa noma ukudlidliza.
