The invention discloses a transfer device special for an excavator manufacturing process. The transfer device comprises a forking transfer base, a connecting assembly and a supporting assembly, wherein the connecting assembly is arranged between the forking transfer base and the supporting assembly, and the supporting assembly is movably connected with the connecting assembly and can rotate relative to the connecting assembly. According to the technical scheme, in the excavator boom transfer process, excavator booms are specially transferred from small to big, universality is good, working efficiency is improved, and the transfer process is more stable and safer. Meanwhile, the situation that painted surfaces of the bottoms of the booms are damaged when the booms are transferred by a forklift directly is avoided, and therefore after-treatment cost is reduced. Furthermore, the transfer device has the advantages of being stable and reliable in operation, low in manufacturing cost, long in service life and the like.
