Cholumikizira cha bulldozer ndi gawo lofunikira pamapangidwe onse ndi ma hydraulic system, omwe ali ndi udindo wotumiza mphamvu, kulumikiza zida zogwirira ntchito, ndikuthandizira njira yoyenda. Kuchita kwake kumakhudza mwachindunji kukhazikika kwa ntchito ndi moyo wautumiki wa zida. Malinga ndi zochitika zosiyanasiyana ntchito, zolumikizira akhoza kugawidwa mu zolumikizira structural (monga zolumikizira chimango, njanji mbale mabawuti) ndi zolumikizira hayidiroliki (monga olowa mafuta chitoliro, hayidiroliki valavu midadada), amene pamodzi kuonetsetsa ntchito odalirika bulldozers pansi katundu katundu ndi kugwedera mikhalidwe.
Kugwiritsa ntchito zolumikizira
ntchito yaikulu ya zomangamanga
Pasitima yapamtunda-zothamanga kwambiri, zomanga mlatho ndi mapulojekiti ena, zolumikizira njanji (monga ma chain rail joints, track plate bolts) zimayenera kupirira kulemera kwa matani makumi a makina onse ndi kukhudzidwa kwa nthaka, ndipo kudalirika kwake kumatsimikizira mwachindunji momwe ntchito yomanga ikuyendera. Mwachitsanzo, maulalo a njanji ya mtundu wina wa bulldozer wotsatiridwa amapangidwa kudzera m'njira zopangira ndi kubisa nyama, ndi moyo wautumiki wa maola opitilira 5000 ndipo ndi oyenera kugwira ntchito tsiku lililonse la 800 cubic metres.
Kupititsa patsogolo Migodi ndi Mphamvu
Muzochitika za migodi, zolumikizira za chipangizo chogwirira ntchito (monga pini yomasulira) zimafunika kuthyola miyala yolimba pafupipafupi, kotero kuti zida zophatikizika za bimetallic (zovala zakunja-zosagwirizana ndi aloyi+zitsulo zolimba zamkati) zimagwiritsidwa ntchito kuwonetsetsa kuti zisatayike komanso kupewa kusweka. Pini yomasula ya bulldozer ya migodi yasinthidwa katatu pa moyo wautumiki poyerekeza ndi zida zachitsulo zachikhalidwe kudzera muukadaulo uwu.
