The invention relates to a winding device and a precast beam hoisting method. The winding device comprises a portal frame, a hoisting mechanism and a protection device, the portal frame is arranged on the ground, walking wheels are arranged at the bottom of the portal frame, the hoisting mechanism comprises a motor, a winding drum and a steel cable, and the protection device comprises a fixing shaft, a rotating wheel, a first action ring, a second action ring, a control ring, a clamping block, a balancing weight and a brake rod set. The steel cable is pulled out of the winding drum and wound on the slope sliding table for preset turns and then droops to suspend a heavy object. During working, the control ring is matched with the first action ring and the second action ring, so that the brake rod group has different deflection directions and deflection angles, and then different brake strategies are provided during heavy-load top rushing, heavy-load falling, light-load top rushing and light-load falling; in th
