Phindu lalikulu la mapepala a rabara ofukula ndikutha kuchepetsa kwambiri phokoso ndi kugwedezeka poyerekeza ndi njira zina zachitsulo. Makina olemera omwe ali ndi makina ofukula mphira akugwira ntchito mwakachetechete, zomwe ndizofunikira kwambiri pomanga matawuni okhala ndi malamulo okhwima a phokoso. Zowonongeka zachilengedwe za raba zimayamwa kugwedezeka, kumathandizira kuti wogwiritsa ntchito azitonthozeka komanso kuchepetsa kutopa nthawi yayitali. Izi zimapangitsama track pads a excavatorchisankho chabwino kwambiri pama projekiti pafupi ndi zipatala, masukulu, kapena malo okhala. Kuphatikiza apo, kugwedezeka kocheperako kumachepetsa kupsinjika pamakina apansi pamakina, kumakulitsa moyo wazinthu zina monga zodzigudubuza ndi ma sprocket. Kwa makontrakitala omwe akufuna kukonza malo ogwira ntchito komanso kutsatira miyezo ya chilengedwe, zofufutira zopangidwa kuchokera ku mphira wapamwamba ndi njira yabwino kwambiri.

Pogwira ntchito pamalo osalimba monga phula, mipanda, kapena pansi m'nyumba, zoyatsira mphira zimalepheretsa kuwonongeka komwe kungachitike ndi zitsulo zachitsulo. Chikhalidwe chosapweteka champhira zokumba excavatorzimatsimikizira kuti malo omalizidwa amakhalabe osasunthika, kuthetsa kukonzanso kokwera mtengo kapena kukonzanso. Izi zimapangitsa kuti zofukula zikhale zabwino pama projekiti am'matauni, makonzedwe a zochitika, ndi malo ogulitsa mafakitale komwe chitetezo chapansi ndichofunikira. Mosiyana ndi mapepala achitsulo, mitundu ya mphira imagawira kulemera mofanana, kuchepetsa kuthamanga kwa nthaka ndikuletsa ma indentation. Makampani ambiri okongoletsa malo ndi othandiza amakonda zofufutira kuti athe kugwira ntchito pazifukwa zovutirapo popanda kusiya zizindikiro kapena kuvulaza mwadongosolo.
