Rantai undhak-undhakan eskalator minangka komponen kunci sing nyambungake lan nggerakake undhak-undhakan eskalator. Biasane digawe saka baja paduan kekuatan dhuwur lan kasusun saka serangkaian pranala rantai sing digawe kanthi presisi. Saben pranala ngalami proses perawatan panas khusus kanggo mesthekake yen nduweni kekuatan tarik, tahan aus, lan tahan lelah sing dhuwur banget.
Rantai langkah nyambungake kabeh langkah eskalator lan mbentuk struktur cincin tertutup. Nalika eskalator diwiwiti, piranti penggerak nggerakake rantai langkah supaya obah, saengga narik langkah supaya sirkulasi ing sadawane jalur sing wis ditemtokake kanggo nggayuh fungsi transportasi penumpang.
Kita nyedhiyakake seri rantai langkah saka macem-macem merek:
