Njira zofukula zinthu zakalendi mtundu watsopano wa maulendo a chassis omwe amagwiritsidwa ntchito pa ma excavator ang'onoang'ono ndi makina ena omanga apakatikati ndi akuluakulu. Ili ndi gawo loyenda lokhala ngati loyenda lokhala ndi ma cores angapo ndi chingwe cha waya chomwe chili mu rabara. Njira ya rabara ingagwiritsidwe ntchito kwambiri pamakina oyendera monga ulimi, makina omanga ndi omanga, monga: ma excavator oyendayenda, ma loader, magalimoto otayira zinyalala, magalimoto oyendera, ndi zina zotero. Ili ndi ubwino wa phokoso lochepa, kugwedezeka pang'ono, komanso kugwira ntchito bwino.

Musawononge pamwamba pa msewu, chiŵerengero cha kuthamanga kwa nthaka ndi chochepa, ndipo zida zapadera zimalowa m'malo mwa njanji zachitsulo ndi matayala. Pakadali pano, tagwiritsa ntchito njira yopanda malumikizano opangira zinthu komanso njira yopangira njanji za raba.

Njira ya rabara yopanda cholumikizira imagonjetsa zofooka za njira ya rabara yachizolowezi yolumikizira yomwe ndi yosavuta kuswa ndi kusweka pa cholumikizira cha lap mutagwiritsa ntchito nthawi yayitali, ndipo imawonjezera nthawi yogwira ntchito ya njira ya rabara. Ilinso yapamwamba kwambiri kuposa njira yachizolowezi. Ili ndi mphamvu yolimba komanso moyo wautali.
