LB 35.1

I-LB 35.1 iyisixhumi esisha se-rig yokubhoboza ye-LB 28-320 esivele ibonakale. Ukubhoboza nge-Kelly, i-double rotary head kanye ne-continuous flight auger kuyizindlela ezivamile. Phakathi kwezici zayo ezinkulu kukhona ukuthuthwa okulula okuhlanganiswe nomholi ophindwe kabili kanye nendawo yokusebenza enobubanzi ngenxa ye-kinematics ye-parallel. Ngaphezu kwalokho, i-LB 35.1 inomhola oqinile ongabamba kalula ama-torques aphezulu kanye namandla amakhulu okudonsa ohlelweni lwe-rope crowed. Lokhu kuqinisekisa izigaba zokusebenza ezisheshayo.
