The utility model discloses a small box girder hoisting rigging, and relates to the technical field of hoisting tools, the small box girder hoisting rigging comprises a hoisting seat, and the bottom of the hoisting seat is rotatably connected with a connecting rod. Through cooperative arrangement of the buckle, the spring, the connecting bolt, the limiting ring, the abutting rod and other structures, during hoisting, the connecting bolt penetrates through the turning lug plate on the small box girder, then passes through the circular through holes in the two ends of the buckle and pushes the abutting rod to abut against the buckle through the spring, and during hoisting, the connecting bolt is pulled to be tightly attached to the buckle due to the gravity effect of the small box girder; through limiting of the limiting ring, the situation that the connecting bolt falls off from the interior of the buckle and loses the gravity compression effect of the small box girder after hoisting is completed is avoided as
