Moralo o ntlafalitsoeng oa Tread:Li-bolts, e leng karolo ea letoto la li-inch, li na le moralo o ikhethang oa ho hatakela o khetholloang ka bophahamo bo fapaneng kapa bophara bo haufi le shaft. Moqapi ona o thusa ho tiisa butle-butle, ho fokotsa kotsi ea ho ts'oara le ho senya sebaka sa ho nyalana ha ho ntse ho tiisa khokahanyo e sireletsehileng le e tsitsitseng.

Tšireletseho e Matlafalitsoeng:Boemo ba liboutu tsena bo fana ka ho ts'oara le ho ts'oara hantle, ho etsa hore li tšoanelehe bakeng sa lits'ebetso moo ho hanyetsanang ha ho thella ho leng bohlokoa, joalo ka litepisi, lirampi le litepisi tsa lere. Mehato e ntseng e eketseha e fa basebedisi sebaka se tsitsitseng, se matlafatsang tšireletseho maemong a ka hare le a ka ntle.

Lisebelisoa tse fapaneng:Li-bolts tsa mehato li fumana lits'ebetso tse fapaneng ho pholletsa le liindasteri, ho kenyeletsoa kaho, lipalangoang le lits'ebeletso. Ho tloha ho fumana libaka tsa phihlello lipalong tsa ts'ebeliso ho isa ho ho fana ka tsela e bolokehileng holim'a li-platform tse phahameng, liboutu tsena li fana ka tharollo e tšepahalang ea ho tiisa meaho le lisebelisoa tse fapaneng.

Khetho ea Lintho:E fumaneha ka mefuta e mengata ea lisebelisoa, ho kenyelletsa le tšepe ea carbon, tšepe e sa hloekang, le li-alloys tse se nang ferrous, li-bolts tsa mehato li ka etsoa ho finyella litlhoko tse khethehileng tsa tikoloho le ts'ebetso. Lintlha tsa khetho ea thepa li kenyelletsa ho hanyetsa kutu, matla, le ho lumellana le likarolo tsa ho nyalana.

Likhetho tsa ho Itloaetsa:Li-bolts tsa mohato li ka etsoa ka mokhoa o ikhethileng ka likarolo tse kang li-anti-corrosion coatings, mekhoa ea ho notlela likhoele, kapa li-finishi tse khethehileng ho ntlafatsa ts'ebetso ea tsona le bophelo bo bolelele maemong a itseng a ts'ebetso. Ho itloaetsa ho netefatsa hore liboutu li fihlela litlhoko tse ikhethang tsa ts'ebeliso e 'ngoe le e' ngoe ka katleho.

Ho Ikamahanya le Maemo:Ho kopana le litekanyetso tsa indasteri tse kang ASTM le ANSI li netefatsa boleng le ho tšepahala ha li-bolts tsa mehato. Ho lumellana le litekanyetso tsena ho fana ka tiisetso ea ts'ebetso le ho lumellana, ho etsa hore e be khetho e tšepahalang bakeng sa merero ea bohlokoa ea litšebeletso tsa motheo le ea kaho.

Kemiso le Tlhokomelo:Ho kenya ts'ebetso e nepahetseng le tlhokomelo ea nako le nako ho bohlokoa bakeng sa ho eketsa ts'ebetso le nako ea bophelo ea li-bolts tsa mehato. Ho latela lintlha tse khothaletsoang tsa torque le linako tsa tlhahlobo ho thusa ho netefatsa boits'oaro bo nepahetseng le ho thibela ho hloleha pele ho nako.
