Ipayipi lokubhoboza elingu-89mm lokumba umthombo wamanzi ngentambo ye-API IF
Lo mthombo wamanzi wokubhoboza ipayipi, uhlobo olufushanisiwe lwepayipi lokubhoboza eliphansi, liwuhlobo lwenduku yokubhoboza eyisicaba yangaphandle.Isetshenziswa kakhulu ekubhobolweni kwe-rotary percussive equkethe amagesi noketshezi.Izingxenye zayo eziyinhloko zihlanganisa umzimba wepayipi (induku) kanye nelunga.
Ipayipi lethu lokubhoboza imbobo phansi lakhiwe ngokusekelwe kumazinga e-API.Futhi ngokwezidingo ezithile, siphinde sinikeze lolu hlobo lwepayipi lokubhoboza i-DTH emibhalweni ehlukene yaseShayina neyaseMelika.
Ngokuqondene nezinzuzo zayo, inezici zokuqina okukhulu, umthamo omuhle wokuvala, isakhiwo sangaphandle esiyisicaba, kanye ne-torque ephansi nokumelana lapho ijikeleza.
Mayelana nokupakishwa, inqwaba yamapayipi okubhoboza i-DTH izopakishwa ngesethi eyodwa yohlaka lwensimbi, futhi inqwaba izoba namapayipi okubhola angama-30 kuya kwangama-40.
