The invention provides a novel high-speed lift door which includes a door frame, a door panel, a rotating shaft, chains, a pair of tension springs and a power unit, wherein the door frame includes vertical door frames and a horizontal door frame which is perpendicular to the vertical door frames and fixed at the top ends of the vertical door frames; door panel sliding rails in smooth connection are arranged on both sides of the door frame in an opposite manner; clamping positions of the door panel are mounted in the sliding rails of the door panel; the rotating shaft is horizontally fixed at the top ends of the vertical door frames; a transmission chain wheel is fixedly arranged on each of both sides of the rotating shaft; one ends of the pair of tension springs are fixed on both sides of the tail end of the door frame, and the other ends of the tension springs are fixedly connected with one ends of the pair of chains; the other ends of the chains bypass the transmission chain wheels and are fixedly connected with both sides of the bottom end of the door panel; the output shaft of the power unit is fixedly connected with the rotating shaft. According to the novel high-speed lift door provided by the invention, the chains, tension springs and transmission chain wheels are used to replace the conventional steel wire rope and rope pulley, so that the problem of derail during the high-speed running of the steel wire rope is avoided, and the high-speed lifting of the lift door is realized.
