Isidlulisi sebhande sihlola isisindo sezinto ezidlulayo kudivayisi yokulinganisa ukuze kuqinisekiswe isisindo sezinto ezisetshenziswayo kutheyiphu; inzwa yokulinganisa isivinini sedijithali efakwe emsila ngokuqhubekayo ikala isivinini sokusebenza sedivayisi yokondla, ukuphuma komfutho wenzwa yesivinini kuhlobene ngokuqondile nesivinini sedivayisi yokondla; isignali yesivinini kanye nenzwa yesisindo kuthunyelwa kusilawuli sedivayisi ephakelayo ndawonye, i-microprocessor kusilawuli ibhekana nalawa masignali futhi ibonise ukugeleza okuhlanganisayo noma ukulethwa okusheshayo. Leli zinga lokugeleza liqhathaniswa nezinga lokugeleza elimisiwe, imitha yokulawula ukuphuma kwesignali ilawula isidluliseli sebhande futhi ibona imfuneko yomthamo. Isidlulisi sebhande sakhiwe uhlaka, ibhande lokudlulisela, isigubhu sebhande, idivayisi ye-tension kanye nedivayisi yokushayela. Umzimba womshini uxhunywe ipuleti lensimbi lekhwalithi ephezulu futhi umehluko wobude phakathi kwezisekelo zangaphambili nangemuva zakha uhlaka olunokuthambekela okuthile kwe-engeli endizeni. Isigubhu sebhande kanye ne-roller yenkampani zifakwe kuhlaka ukuze zishayele futhi zisekele ibhande lokudlulisela. Izindlela zokushayela zihlanganisa ukunciphisa ukushayela kwezimoto kanye nokushayela kwe-pulley motorized.
