The invention discloses a large-height escalator with a heavy-load safety step chain. The large-height escalator comprises the heavy-load safety step chain, and the heavy-load safety step chain comprises a plurality of chain link units which are circularly connected; each chain link unit comprises inner chain plates, outer chain plates and pin shafts, wherein the inner chain plates are configured in a paired manner and are mutually parallel, the outer chain plates are configured in a paired manner and are mutually parallel, and every two adjacent inner chain plates are connected through one outer chain plate and connected with the outer chain plates through the pin shafts; the pin shafts are sleeved with inner rolling wheels which are sleeved with sleeves, the thickness of the outer chain plates is 10mm, and the width of the outer chain plates is 7.5mm; and the lowest tensile limit loads of the heavy-load safety step chain are 520KN. The escalator has the beneficial effects of being high in safety and capable of meeting the requirements and being widely applied to an occasion where the lifting height is below 50 meters.
