The invention discloses a truss hoisting and mounting device for bridge construction, and mainly relates to the field of bridge construction. The device comprises a plurality of top plates, side plates are symmetrically and rotationally connected to the two sides of each top plate, lifting hooks are arranged at the tops of the top plates, adjusting rods are symmetrically and rotationally connectedto the two sides of each top plate, the bottoms of the adjusting rods are rotationally connected with the side plates, telescopic rods are rotationally connected to the top plates, a plurality of grooves are formed in the tops of the horizontal parts of the side plates, and lifting tables are arranged in the grooves. A rolling wheel is arranged on one lifting table, top blocks are arranged on theother lifting tables, positioning holes are formed in every two opposite side plates, positioning rods are movably inserted into the opposite positioning holes, lifting rods are slidably connected tothe top of the top plates, a plurality of auxiliary rods are rotatably connected to the top plates, sliding blocks are slidably connected to the auxiliary rods, and the sliding blocks are rotatably connected with the side faces of the lifting rods. The device has the beneficial effects that the contact area between a hoisting point and a truss is increased, the hoisting safety of the truss is improved, and the construction progress is guaranteed.
