The invention discloses an adjustable lifting tool for a vertical unstable joist piece type structure, and relates to the technical field of bridge steel structure lifting. The adjustable lifting toolcomprises a rod fixing system and a lifting lug system. The rod fixing system comprises a framework and a locking rod. An opening is formed in one side of the fixing system. A limiting rod is arranged on the opening of the fixing system, the space defined by the frame and the limiting rod is used for containing inclined rods of the to-be-lifted joist piece type structure, and the locking rod penetrates through the limiting rod and the frame to be right opposite to the side edge of the limiting rod. The lifting lug system comprises a main lifting lug, an upper lug plate and a lower lug plate,wherein the main lifting lug is arranged above the frame and used for lifting the to-be-lifted joist piece type structure and assisting the adjustable lifting tool in disassembly, the upper lug plateis arranged below an upper cross rod of the to-be-lifted joist piece type structure and used for connecting the adjustable lifting tool and the upper cross rod of the to-be-lifted joist piece type structure, and the lower lug plate is arranged above a lower cross rod of the to-be-lifted joist piece type structure. Normal lifting of the to-be-lifted joist piece type structure can be effectively guaranteed.
