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.

    本发明涉及工程设备技术领域,提供一种活动配重提升装置、控制该装置的方法及工程机械。其中,该活动配重提升装置包括:转台(1);提升油缸(10),所述提升油缸的缸筒固定于所述转台上,所述提升油缸的提升活塞杆(5)与配重(2)连接,所述提升活塞杆上设置有第一通孔(11);锁定机构,所述锁定机构包括安全销(6),所述安全销具有插入于所述第一通孔以对将所述配重提升至指定位置后的所述提升活塞杆进行锁定的锁定位置以及脱离于所述第一通孔以使所述提升活塞杆能够带动所述配重移动的解锁位置。该活动配重提升装置及工程机械能对将配重提升至指定位置后的提升油缸进行机械锁定,且锁定方式更可靠。
