Izixhumanisi zethrekhi yezandla zenziwa ngokuya ngezinga le-OEM.Zonke izixhumanisi zethrekhi ye-Crafts zenziwe ngensimbi ekhethekile engu-35MnB.Uma siqhathanisa nezinye izixhumanisi zamathrekhi enziwe ngo-40MnB noma 40Mn, izixhumanisi zamathrekhi ethu zingcono ekuqineni nasekumelaneni okulimazayo.
Izinqubo zomshini ziyinqubo evamile yokukhiqiza kuzo zonke izixhumanisi zethrekhi, okuhlanganisa ukugaya indawo engaphezulu, ukubhoboza imbobo yebhawodi, ingaphezulu lebhawodi elibushelelezi, imbobo yephini lomshini ukuya kusayizi othize.Ngaphandle kwesici esibalulekile, ukwelashwa kokushisa futhi kuyinqubo eyinhloko yokuqinisekisa ikhwalithi yezixhumanisi zethrekhi.Imisebenzi yezandla ithatha inqubo yokwelapha ukushisa oku-2 kusixhumanisi sethrekhi ngasinye: okokuqala, ukucwengisiswa okushisayo - sonke isixhumanisi siqinisa i-HRB 270 ° - 297°;okwesibili, ukuqina kwefrikhwensi yaphakathi – ithrekhi ixhumanisa ukwelashwa kokushisa okungaphezulu HRC52° - 56°, ukushona ku-6mm.
Ngemuva kwezinqubo ezimbili zokwelashwa kokushisa, izixhumanisi zamathrekhi ethu ziba namandla kakhulu futhi zihlale isikhathi eside, okukulethela impilo ende yesevisi futhi akonge kangcono.
Izixhumanisi zamathrekhi zibizwa nangokuthi amaketanga ethrekhi, ngokuvamile, kunezimbobo zokuxhuma ezi-4 ku-track plate kanye nezinye izimbobo zokuhlanza ezi-2 phakathi nendawo.Izimbobo zokuhlanza ziyakwazi ukususa umhlaba wepuleti ngokuzenzakalelayo.Amapuleti amabili angomakhelwane anengxenye yokunqwabelanisa.Ukuze ugweme izingcezu zamatshe ezibhajwe phakathi futhi zidale umonakalo, amapuleti okulandelela anomumo onxantathu angasetshenziswa uma i-excavator igijima emhlabathini omanzi, ngoba umumo owunxantathu ungacindezela umhlabathi othambile futhi wandise amandla okusekela.Njengoba kunebanga elibanzi lokukhetha, izixhumanisi zethrekhi yezandla ziyasebenza kumodeli ekhethekile yama-excavators ohlobo lwesiseshi namagandaganda ukusuka ku-6t kuya ku-100t.Asetshenziswa kabanzi kuma-excavators wemikhiqizo edumile kanye namagandaganda, njengeCaterpillar, Komatsu, Hitachi, Kobelco, neHyundai njll.
