The invention discloses a synchronous lifting device. The synchronous lifting device comprises a lead screw, a worm wheel, a multi-point synchronous worm rod, a driving hand wheel, a slide sleeve, a nut and a frame, wherein the lead screw is connected to the frame; the worm wheel is connected with the nut; the multi-point synchronous worm rod and the worm wheel are engaged; the driving hand wheel is connected with the multi-point synchronous worm rod; and the nut is mounted in the slide sleeve, and is connected with the lead screw. The synchronous lifting device is simple in structure and convenient to operate, uses a conventional transmission device to change the operation mode, changes the operation wasting labor, time and force to simple operation of saving labor, time and force, can easily finish the rope penetration, and improves the efficiency by above 50%.
