The invention relates to the technical field of engineering equipment, and provides a movable balance weight lifting device, a method and engineering machine for controlling the device. The movable balance weight lifting device comprises a rotary table (1), a lifting oil cylinder (10) and a locking mechanism; a cylinder barrel of the lifting oil cylinder (10) is fixed to the rotary table, and a lifting piston rod (5) of the lifting oil cylinder is connected with a balance weight (2); a first through hole (11) is formed in the lifting piston rod; the locking mechanism comprises a safety pin (6), and the safety pin is provided with a locking position and an unlocking position, the locking position is inserted into the first through hole to lock the lifting piston rod after the balance weightis lifted to the designated position, and the unlocking position is separated from the first through hole to enable the lifting piston rod to drive the balance weight to move. According to the movable balance weight lifting device and the engineering machine, the lifting oil cylinder can be mechanically locked after the balance weight is lifted to the designated position, and the locking mode ismore reliable.
