The invention discloses a torsion-proof arm section structure and an electric derrick thereof. The torsion-proof arm section structure comprises an arm section frame structure (I). One end of the arm section frame structure (I) is connected with a rocker arm. The torsion-proof arm section structure is characterized in that an arm section head structure (II) is connected to the outer side of the other end of the arm section frame structure (I), a cross beam (III) is connected to the lower portion of the arm section head structure (II), the installation direction of the arm section frame structure (I) is perpendicular to the length direction of the cross beam (III) in different planes, a second pulley assembly communicating with a steel wire rope between the rocker arm and a lifting hook is arranged on the cross beam (III), and the second pulley assembly comprises a first anti-winding pulley with the rotating plane parallel to the vertical plane of an arm frame and a second anti-winding pulley with the rotating plane perpendicular to the vertical plane of the arm frame. The torsion-proof arm section structure and the electric derrick are reasonable in structural design, safe, reliable, detachable, convenient to transport and capable of effectively preventing twisting under the condition that the structural strength and use requirements are met.
