Iikreni zedekhizizixhobo ezibalulekileyo ezisetyenziswa kakhulu kwiindawo zaselwandle nakwimizi-mveliso ukuphakamisa nokuhambisa imithwalo enzima. Ezi cranes zihlala zixhonywa kwidekhi yenqanawa, inqanawa, okanye iqonga laselunxwemeni ukuze kube lula ukuphatha imithwalo kakuhle kunye nokuhambisa izinto.
Ingundoqo yokusebenza kwekreyini yedekhi ikwindlela yoyilo lwayo loomatshini, oludla ngokuquka inkqubo ye-boom, i-winch, kunye ne-winch. I-boom yingalo ende ephuma kwisiseko sekreyini, eyivumela ukuba ifikelele ngaphaya komphetho wedekhi. I-winch inoxanduva lokuphakamisa nokwehlisa umthwalo, ngelixa inkqubo ye-winch inika amandla afunekayo ukwenza ezi zenzo.
Ukusebenza kwekreyini yedekhi kuqala ngomqhubi evavanya umthwalo oza kuphakanyiswa. Emva kokubopha umthwalo esebenzisa isilingi okanye ihoko, umqhubi uqhuba ikreyini esebenzisa iphaneli yokulawula. Ulawulo ludla ngokuquka iilevers okanye iijoysticks zokulawula ngokuchanekileyo i-boom kunye ne-winch. Umqhubi unokwandisa kwaye abuyisele i-boom, aphakamise kwaye anciphise umthwalo, aze ajikelezise ikreyini ukuze ibeke umthwalo ngokuchanekileyo.
Iikreyini zedekhi zixhotyiswe ngezixhobo zokhuseleko ukuthintela iingozi nokuqinisekisa ukuphathwa ngokukhuselekileyo kwemithwalo enzima. Ezi zixhobo zinokubandakanya izinzwa zokugqithisa kakhulu, iiswitshi zokunciphisa, kunye namaqhosha okuma ngexesha likaxakeka. Ukongeza, abaqhubi badla ngokufuna uqeqesho ukuze baqonde amandla kunye nemida yekreyini ukuqinisekisa ukusebenza ngokukhuselekileyo nangokufanelekileyo.
