Kutheni ihoist yetsheyini ye-1 ton 3 yeemitha ityibilika?

Ikhonkco lekhonkco le-1-toni ye-3 yemitha yekhonkco liya kutyibilika emva kokusetyenziswa ixesha elithile. Kuqhubekani? Ngezantsi umhleli we-Chenli uya kukunika intshayelelo eneenkcukacha:

Isenzeko sokutyibilika kwe-inverted chain hoist kungenxa yokuba kukho ingxaki kwisixhobo. Ngeli xesha, kuyimfuneko ukuyeka ukusebenza kwaye ukhangele izixhobo. Ukuba awusebenzi ngokomthwalo wokuphakamisa ochaziweyo kunye nomthwalo ogqithisileyo, ukutyibilika kuya kwenzeka; ngexesha lokusetyenziswa kwansuku zonke, ipleyiti yokuxuba ifakwe ioli kunye nezinye izinto ezingcolileyo, ezinciphisa amandla okuphikisana kunye nokutyibilika kuya kwenzeka; ukukhuhlana komgangatho ombi Ukuba iiblades ziqhubeka ziba mncinci ngexesha lokusetyenziswa, ukutyibilika kunokwenzeka; ukuba intwasahlobo kwi-pawl kwisixhobo sokuqhobosha siyakhululeka, ukutyibilika kunokwenzeka kwakhona.
