Product Specification

High Speed Turning Block for Transmission Line Stringing | Large Nylon Sheave, Heavy-Duty Galvanized Steel

Product Overview

The High Speed Turning Block is a professional stringing pulley designed for overhead transmission line construction, conductor installation, and high-speed cable pulling applications. It is primarily used to change the running direction of conductors, steel wire ropes, pilot ropes, and pulling ropes while maintaining smooth movement and minimizing friction during stringing operations.

Featuring a large-diameter high-strength nylon sheave, precision bearings, and a hot-dip galvanized steel frame, this turning block provides excellent wear resistance, low rolling resistance, and stable operation under high-speed and heavy-load conditions. The lifting eye design allows quick installation on towers, crossarms, or temporary structures, making it an essential tool for transmission line contractors and utility construction companies.

Designed for demanding field environments, the High Speed Turning Block helps improve pulling efficiency, reduce conductor wear, and ensure safe, reliable performance throughout transmission and distribution line construction projects.
