description The utility model relates to the technical field of excavator movable arm workpiece machining, and particularly discloses a large-tonnage lifting positioner device which comprises a fixed rotary power spindle box, a movable rotary power spindle box, two sets of lifting assemblies and a ground moving track. The rotating shafts are respectively arranged on the fixed rotating power spindle box and the movable rotating power spindle box in a matched manner through rotating supports; the bottom of the fixed rotary power spindle box is fixedly connected with the ground, the movable rotary power spindle box is installed on a movable sliding table in a ground movable track, and the ground movable track is fixedly arranged on the ground. Lifting tables are arranged in the lifting assemblies, and the lifting tables in the two sets of lifting assemblies are connected with the two ends of a workpiece to be machined correspondingly; the movable arm welding tool has great compatibility in the length direction of a workpiec
