The invention discloses a material lifting device. The material lifting device comprises a driving mechanism (2) and a holding mechanism (3), the holding mechanism (3) is arranged in a quenching chamber (1) and can vertically move in the quenching chamber (1), the cross-sectional shape of the holding mechanism (3) is matched with the shape of a through hole (41) in a heating door (4) of a heating chamber, the top end of the holding mechanism (3) is opposite to the through hole (41) so that the holding mechanism (3) can enter the heating chamber when the heating door (4) is closed, and the driving mechanism (2) is used for driving the holding mechanism (3) to vertically move in the quenching chamber (1). According to the material lifting device, time consumed by materials entering the quenching chamber from the heating chamber is shortened when the heating door is opened.
