I-TR460 Rotary Drilling Rig ingumshini omkhulu wenqwaba. Njengamanje, i-tonnage rotary drilling rig isetshenziswa kakhulu ngamakhasimende asendaweni eyinkimbinkimbi yokwakheka komhlaba. Ngaphezu kwalokho, izinqwaba zemigodi emikhulu futhi ejulile iyadingeka olwandle olungaphesheya nangaphesheya kwebhuloho lomfula. Ngakho-ke, ngokusho kwalezi zizathu ezimbili ezingenhla, sicwaninge sathuthukisa i-TR460 rotary drilling rig enezinzuzo zokuzinza okuphezulu, inqwaba enkulu futhi ejulile futhi elula ukuthuthwa.
Isakhiwo sokwesekwa konxantathu sinciphisa ukujikisa indawo futhi sikhuphula ukuzinza kwe-rig yokumba imishini.
Iwinji enkulu efakwe ngemuva isebenzisa ama-motors aphindwe kabili, izinciphisi eziphindwe kabili kanye nokwakheka kwesigubhu esisodwa okugwema ukugoqa ngentambo.
Isixuku indophi uhlelo yokutholwa, unhlangothi 9m. Kokubili ukuqina kwesixuku nokushaywa unhlangothi kukhulu kunokwesilinda sohlelo, okulula ukushumeka ikhebula lesistimu yokulawula umfutholuketshezi nogesi kuthuthukisa ukunemba kokulawulwa kwesistimu nejubane lokuphendula.
