The invention discloses a derrick head and a derrick device and relates to the technical field of engineering machines. The derrick head and the derrick device aim at solving the problem that eccentric force on a derrick is too large when an iron tower component is lifted and ensuring the stability and the construction safety of the overall derrick. According to the main technical scheme, the derrick head comprises a stand column and pulley set supporting frames, the stand column is of a hollow structure and is installed at the upper end of a derrick body, two through holes which are arranged oppositely are formed in the outer wall of the stand column, the connecting line of the two through holes penetrates through the center of the stand column, and the two through holes are formed in the same horizontal plane. The two pulley set supporting frames are installed on the parts, below the through holes, of the outer wall of the stand column, and pulley assembly installation parts are arranged at the tail ends of the pulley set supporting frames. The invention further discloses the derrick device which comprises the derrick body and the derrick head, and the derrick head is arranged at the top end of the derrick body. The derrick head and the derrick device are mainly used for erecting of high-voltage iron towers and the like in the electric transmission line construction, and stability and the construction safety are good.
