Tandem Sheave Stringing Block for Transmission Line Construction | Double Sheave Conductor Pulley

Product Introduction

The Tandem Sheave Stringing Block is a professional stringing tool designed for overhead transmission line construction, conductor installation, and cable pulling operations.

Featuring a dual sheave structure with a metal supporting frame and suspension hook, this stringing block provides guided support for conductors during pulling and stringing processes. The tandem pulley configuration helps maintain a controlled conductor path and reduces direct contact between the conductor and construction structures.

This double sheave stringing block is widely used in power transmission projects, utility construction, and electrical installation applications where smooth conductor movement and proper line routing are required.

The product can be used together with tensioners, pulling equipment, and other transmission line construction tools to support efficient field operations.

Product Specifications
