Amaketango ohlobo lwephinikhodi abuye aziwe ngokuthi amaketango okusetshenzwa kulengwa, asetshenziswa ikakhulukazi ezinhlelweni lapho umthwalo kulindeleke ukuthi usuke ngapha nangapha, ngokungafani ne-D-shackle esetshenziswa ngokuhambisana nesiqondiso somthwalo.
Ezinye izinhlelo zokusebenza ezijwayelekile zamaketango omnsalo wohlobo lwephini zihlanganisa:
Imboni yasolwandle:Isetshenziselwa ukumisa ihange nokuphakamisa imithwalo esindayo, njengamahange, amaketango, noma izintambo.
Imboni yokudoba:Isetshenziselwa ukuhlanganisa oseyili noma ukumisa imithwalo emikhiqizweni yasetiyetha, amakhonsathi, neminye imicimbi yokuzijabulisa.
Imboni yezokwakha:Isetshenziswa kuma-cranes, ama-excavators, nakweminye imishini esindayo yokuphakamisa nokuphakamisa izinto zokwakha njengemishayo yensimbi, amapayipi, namabhulokhi kakhonkolo.
I-shackle iyithuluzi elisetshenziswa ukuvula iketango noma uxhumano lwezintambo futhi livame ukusetshenziswa ekuphakamiseni imisebenzi, impi, izindiza zomphakathi, kanye nezimoto. Ngokuvamile iqukethe izingxenye ezimbili: i-shackle ngokwayo kanye nenduku yokusebenza.
Amaketanga ayahlukahluka ngokuma nangosayizi ngezinhloso ezahlukene. Emkhakheni wezimboni, amanye amaketango angaba makhulu futhi adinga amathuluzi akhethekile ukuze asebenze, kanti amanye mancane futhi angasebenza ngesandla. Isibonelo, lapho kwakhiwa izakhiwo ezinkulu zensimbi, izibopho ezinkulu ziyadingeka ukuze kuxhunywe futhi kuvikeleke amaketanga noma izintambo.
Induku yokusebenza nayo iyingxenye ebalulekile ye-shackle. Induku yokusebenza ingaxhunywa ku-shackle ukunikeza ukulawula nokusebenza okungcono. Ubude nokuma kwama-levers kuyahlukahluka ngezinhloso ezihlukene, isibonelo, lapho uqaqa izingxenye ezihlukahlukene nezinsiza zendiza, ama-lever angasetshenziswa ukubeka ngokuphephile iketango nokwenza umsebenzi wokukhipha ube lula futhi unembe kakhudlwana.
Sengiphetha, i-shackle iyithuluzi eliwusizo kakhulu elingasiza abasebenzi, onjiniyela kanye namakhenikha ukuba bavule ngokushesha futhi baxhume amaketanga noma izintambo, ukuze kuqiniswe futhi kuqiniswe izinhlobo ezihlukahlukene zezakhiwo, futhi kuthuthukiswe ukusebenza kahle nokuphepha komsebenzi.
1. Izinto Ezikhethiwe: Ukukhetha okuqinile kwezinto ezingavuthiwe, izendlalelo zokuhlola, ukukhiqizwa nokucubungula ngokuhambisana nezindinganiso ezifanele.
2. Ubuso: indawo ebushelelezi ngaphandle kwentambo yembobo ejulile, amazinyo abukhali wesikulufu
