Umshini wokuqhumisa wohlobo lwe-Crawleryamukela umshini wokuqhumisa isihlabathi we-cantilever we-centrifugal, one-engeli enkulu yokuqagela, ukusebenza kahle okuphezulu futhi ayikho i-engeli efile. Impilo ende yenkonzo kanye nesakhiwo esilula; Ithrekhi yenjoloba engagqoki inciphisa ukungqubuzana nokulimala endaweni yokusebenza, futhi inciphisa umsindo womshini; Umshini wokuqhumisa isibhamu sesitimela usebenzisa isihlungi sesikhwama se-DMC pulse backwash, futhi ukugcwala kokukhishwa kothuli kuphansi kunemithetho kazwelonke. Leli zinga lithuthukisa kakhulu indawo yokusebenza yabaqhubi.
Umgomo wokusebenza womshini wokuqhumisa isibhamu sohlobo lwesiseshi ulula, kodwa futhi kukhona amaphuzu amaningi aphawulekayo. Ngemuva kokwengeza inombolo ecacisiwe yama-workpieces ekamelweni lokuhlanza, vala umnyango, qala umshini, shayela ama-workpieces ngokusebenzisa i-roller, qala ukujikeleza, bese uphonsa umshini we-sandblasting ngesivinini esikhulu.
Ama-projectiles akha induku emise okwefeni futhi ashaya ngokulinganayo indawo yokusebenza ukuze ihlanzwe. Ama-projectile ajikijelwe kanye nezinhlayiya zesihlabathi zigeleza zisuka emigodini emincane yethrekhi ziye ku-screw conveyor ezansi, futhi zithunyelwa ku-elevator nge-screw conveyor. I-hopper ihlukaniswa ibe isihlukanisi ukuze kuhlukaniswe.
Igesi enothuli imuncwa kumqoqi wothuli ngefeni, ihlungwe emoyeni ohlanzekile bese ikhishelwa emkhathini. Uthuli lomshini oqhumisayo wohlobo lwe-crawler luqhunyiswa lubuyiselwe ebhokisini lokuqoqa uthuli ngaphansi komqoqi wothuli ngomoya, futhi abasebenzisi bangalususa njalo.
