Izicathulo zomkhondo ezisetyenziswa ngokuqhelekileyo zihlulwe zibe ziintlobo ezintathu ngokwemilo yomhlaba. Kukho iintlobo ezintathu zembambo enye, iimbambo ezintathu kunye nomzantsi osicaba. Kukho nezihlangu zomkhondo ezinxantathu zomntu ngamnye. Izihlangu zomkhondo ezilomeleziweyo zodwa zisetyenziswa ikakhulu kwiibulldozers kunye neetrektara, kuba olu hlobo lomatshini lufuna izihlangu zomkhondo ukuba zibe ne-traction ephezulu ngaphambi kohlengahlengiso. Nangona kunjalo, ayifane isetyenziswe kumatshini wokumba, kwaye olu hlobo lwesihlangu somzila lusetyenziswa kuphela xa isakhelo se-drill sifakwe kumatshini wokumba okanye xa kufuneka i-horizontal thrust enkulu. Utsalo oluphezulu luyafuneka xa ujika usuka emntwaneni, ngoko ke ibar yokukhasa ephezulu (okt, i-crawler spur) iya kuwucudisa kude umhlaba (okanye umhlaba) phakathi kwemivalo ye-crawler, kwaye ichaphazele ukushukuma kwe-excavator.
Isihlangu somkhondo wensimbi sinokwahlulwa sibe: ipleyiti yokwemba, ipleyiti ye-bulldozer, ezi zimbini zisetyenziswa ngokuqhelekileyo, zisebenzisa intsimbi yecandelo njengento ekrwada. Kukwakho nomgangatho omanzi osetyenziswa ziibulldozers, ezaziwa njenge "triangular plates", eziziipleyiti eziphosiweyo. Olunye uhlobo lwe-slab yokuphosa lusetyenziswa kwi-crawler cranes. Ubunzima beli slab buncinci njengeekhilogram zamashumi, kwaye buninzi beekhilogram ezilikhulu.
