Izinhlangothi eziphezulu nezingezansi zebhande lokuhambisa ziyathinteka futhi zizimele. Ngokuvamile, ukufana okunganele kwama-idlers aphansi kanye nokulingana kwama-roller kuzobangela ukuphambuka ohlangothini olungezansi lwebhande lokuhambisa. Isimo sokuthi uhlangothi olungezansi lugijima futhi uhlangothi oluphezulu lujwayelekile ngokuyinhloko kungenxa yedivayisi yokuhlanza embi, i-roller engezansi inamathele ezintweni, ama-roller aphikisayo awalingani, noma ukwesekwa kwe-counterweight kugobile, futhi ama-roller aphansi awalingani. Isimo esithile kufanele silungiswe ngokwesimo sangempela. Ngokuvamile, ukuphambuka okungaphansi kungalungiswa ngokuthuthukisa isimo sokusebenza sedivayisi yokuhlanza, ukususa i-roller nezinto ezinamathele ku-roller, ukulungisa i-roller ephansi engaphansi, i-roller enomumo we-V engaphansi, noma ukufaka i-roller yokuqondisa engaphansi.
