The invention discloses an electric transmission line tower facilitating mechanical construction. The electric transmission line tower facilitating mechanical construction comprises a tower upper bodysection, and further comprises a tower leg section, a plurality of first tower body sections, a plurality of second tower body sections and a plurality of third tower body sections, wherein the firsttower body sections, the second tower body sections and the third tower body sections are arranged into a line from bottom to top and are fixedly connected with one another end to end; the tower upper body section is fixedly arranged above the third tower body section; the first tower body sections are fixedly arranged above the tower leg section; the tower leg section comprises a plurality of tower supporting leg sections; and the tower supporting leg sections are symmetrically and fixedly connected at a position. The structure of a tower body is properly optimized by a reasonable design method, the electric transmission line tower in the prior art is disassembled to implement separate hoisting of the structure of the tower body, safety reliability of high-altitude connection between separate integral hoisting pieces is ensured, mechanical and streamlined assembling efficiency of the structure of the electric transmission tower are improved, the labor intensity is reduced, and the intrinsic safety level of construction and erection of the tower is improved.
