SA-YQ180 Diesel Hydraulic Puller for Overhead Line Stringing | 180kN Power Line Construction Equipment

1. Overview

The SA-YQ180 Diesel Hydraulic Puller is a heavy-duty pulling machine designed for overhead transmission line construction and long-distance conductor stringing. With a maximum pulling force of 180 kN, this model ensures stable, efficient, and safe stringing operations for conductors, optical ground wires (OPGW), and ground wires in high-voltage power line projects.

Built with a powerful diesel engine and advanced hydraulic control system, the SA-YQ180 delivers consistent performance in challenging field conditions.

2. What Is a Hydraulic Puller?

A hydraulic puller is a machine used to pull conductors or OPGW during power transmission line construction.
It provides controlled pulling force, constant tension regulation, and high reliability for maintaining conductor safety and preventing damage.

The SA-YQ180 is specifically engineered for 132kV–500kV line construction.
