The invention discloses an automatic balancing device and method for a tower crane. The automatic balancing device comprises a balancing weight carrier, a movable balancing weight, a sliding rail, a balancing motor, a steering fixed pulley, a hoisting arm torque limiter and a balancing arm torque limiter. The sliding rail and the balancing motor are arranged on the balance arm, the steering fixed pulleys are arranged on the left side and the right side of the balancing motor, an annular steel wire rope is arranged at the driving end of the balancing motor and arranged on the outer sides of the steering fixed pulleys in a sleeving mode, and the movable balancing weight is arranged in the balancing weight carrier. The balancing weight carrier is connected to the steel wire rope and matched with the sliding rail in a sliding mode, the balancing motor drives the balancing weight carrier to slide on the sliding rail through the annular steel wire rope so as to balance the torque of the cargo boom and the torque of the balance arm, and the cargo boom torque limiter and the balance arm torque limiter are arranged at the end of the cargo boom and the end of the balance arm respectively. And the balance weight can be controlled to automatically trim, and the use requirement is met.
