The invention discloses a special hoisting tool for mounting an ash lock lower valve of a Lurgi gasification furnace. The special hoisting tool comprises a cross-shaped supporting frame, and lifting lugs which are arranged on the cross-shaped supporting frame and symmetrically arranged; the circle center of the cross-shaped supporting frame is provided with a supporting steel pipe; a circular supporting plate is arranged at the top of the supporting steel pipe; locking nuts are arranged at the circle centers where the circular supporting plate and the circular supporting plate are connected with the cross-shaped supporting frame; and single-end bolts penetrate into the locking nuts. The special hoisting tool has the effects that a valve head can be locked so that the valve head is in tight contact with a hanger; and the axial and radial positions of the valve head are fixed so that a phenomenon that a sealing surface is damaged because the collision occurs in a hoisting process is prevented, and the condition that valve rod groove holes deviate and cannot be in butt joint also can be avoided. The axial position of the valve head can be adjusted according to readings of a scale rule so that the valve rod and an inner swinging rod are paired and the operation is relatively accurate. The device has a reasonable structure, the hoisting process is safe and reliable, the installation difficulty is extremely reduced and the overhauling schedule is accelerated; and meanwhile, the safety of equipment and workers is guaranteed and occurring of accidents is prevented.
