Umuhengeri uringaniye nturenze guterura umutwaro gusa - irawurinda. Ubugari, buringaniye bwurubuga rugabanya uburemere bwumutwaro ahantu hanini, bigabanya cyane umuvuduko kumwanya uwariwo wose. Iri ni ihame shingiro rya fiziki inyuma yinyuma: Umuvuduko = Imbaraga ÷ Agace. Mugukomeza aho uhurira, ibice bigabanije kugabanya ibyago byo kwangirika kwubutaka, amenyo, no kumenagura - bigatuma bahitamo guterura ibikoresho byoroshye, byarangiye, cyangwa byangiritse byoroshye. Aka gatabo gasobanura ibya fiziki yo gukwirakwiza igitutu, kugereranya imirongo iringaniye nibindi bisubizo byo guterura, kandi bitanga ubuyobozi bufatika bwo guhitamo ubugari bwiburyo bwiburyo bwa porogaramu yawe.

Umuhengeri uringaniye kuri toni 2 mukuzamura kugororotse kurashobora gusa guterura neza toni 1 mugihe ukoresheje kuri 60 °. Ibi ni ukubera ko inguni ya shitingi igira ingaruka ku buryo butaziguye kuri buri kaguru ka shitingi - ntoya inguni iri hagati ya shitingi na horizontal, niko impagarara nini. Ukurikije EN 1492-1 na ASME B30.9, ubushobozi bugomba kugabanuka mugihe imigozi ikoreshwa kumpande cyangwa muburyo bwinshi. Aka gatabo gasobanura ibya fiziki inyuma yibintu bifatika, bitanga imbonerahamwe yubushobozi bwa shitingi iringaniye, kandi itanga ubuyobozi bufatika bwo kubara imizigo ikora neza mubikorwa byukuri byo kwisi.

Umuhengeri uringaniye-uzwi kandi nk'urubuga rwa shitingi cyangwa umukandara - ni kimwe mu bisubizo bikoreshwa cyane mu guterura ibintu mu bwubatsi, mu nganda, no mu bikoresho. Ubwubatsi bwayo busobanurwa nibintu bitatu byingenzi: ibikoresho byo kurubuga, ply layers, nubugari. Hamwe na hamwe, ibi bigena imipaka yumurimo ntarengwa (WLL), guhinduka, no kuramba. Dukurikije EN 1492-1, ibipapuro bikozwe mu mbuga bikozwe muri polyester, polyamide, cyangwa polypropilene bipimwe hamwe n’umutekano 7: 1 kandi byanditseho amabara kubushobozi. Aka gatabo karasobanura uburyo kubaka urubuga, kuboneza, hamwe nubugari bikora kugirango umenye ubushobozi bwimitwaro - nuburyo bwo guhitamo iburyo bwa shitingi ya porogaramu yawe yo guterura.

Kumenya igihe cyo gusezera umugozi wo guterura ni bumwe mu buhanga bukomeye mu kwiba umutekano. Urupapuro rusa nkaho rushobora kuba rwangiritse rushobora kuba rwangiritse rwangiza imbaraga zarwo, mugihe ubwoko bwangirika bugaragara - gukata, gukuramo, gutwika imiti, kwangiza ubushyuhe, no kwangirika kwa UV - buriwese afite ibipimo byihariye byizabukuru byasobanuwe na ASME B30.9, OSHA, na EN 1492. Kubayobora abagenzuzi, abashinzwe umutekano, nabakoresha, iki gitabo kiratanga umurongo ngenderwaho wo gufata ibyemezo byizabukuru.

Igikoresho cyo guterura gishobora gutakaza imbaraga mbere yuko yerekana imyenda igaragara - akenshi nta nteguza. Ubushyuhe bukabije, imirasire ya ultraviolet (UV), hamwe n’imiti ihura n’ibintu bitatu bikunze kubaho bidukikije byangiza fibre synthique. Nk’uko ikigo cya Kanada gishinzwe ubuzima n’umutekano ku kazi (CCOHS) kibitangaza ngo urumuri rw’izuba, ubushuhe, n’ubushyuhe buri hejuru ya 90 ° C (194 ° F) bishobora kwangiza ibice bya nylon na polyester. OSHA ikomeza ivuga ko imbaraga za shitingi ziteshwa agaciro n’izuba n’izuba rya ultraviolet, kandi irasaba kugisha inama uwabikoze cyangwa umuntu wujuje ibyangombwa kugira ngo yongere amafaranga y’izabukuru. Aka gatabo karasuzuma uburyo buri kintu cyibidukikije kigira ingaruka ku busugire bwa shitingi, ibimenyetso byo kuburira gushakisha, nuburyo bwo kurinda ibice byawe byo guterura kunanirwa imburagihe.

Igikoresho cyo guterura hamwe nikintu 7: 1 cyumutekano gifite imbaraga zo kumena inshuro zirindwi igipimo cyakazi cyagenwe. Ibi bivuze ko umugozi wagenwe kuri toni 1 ugomba kwihanganira byibura toni 7 mbere yo gutsindwa. Ibintu 7: 1 byumutekano byateganijwe ningingo zingenzi zinganda zirimo EN 1492-1, EN 1492-2, na AS 4497: 2018 kubice bya sintetike. Iyi ngingo isobanura itandukaniro riri hagati yibintu byumutekano hamwe nakazi ntarengwa, kuki 7: 1 aricyo gipimo cyo gutondekanya sintetike, uburyo ugereranije nubundi bwoko bwibikoresho, nimpamvu iyi ntera yumutekano ari ngombwa mukurinda abakozi numutungo mubikorwa byo guterura isi.
