This 2 x 7t Double Bundle Overhead Line Stringing Equipment is engineered for efficient installation of bundled conductors in power transmission line construction. With a maximum conductor diameter capacity of 46mm and dual 70kN pulling force, this machine delivers reliable performance for demanding electrical infrastructure projects.

Features a closed hydraulic circuit for stepless speed variation in both rotating directions. The machine includes 2 pull pre-setting systems that maintain the pre-set pulling value (even when speed is reduced to zero) by automatically adjusting operation speed according to friction and unexpected loads.
