Product Description

Stringing Machine Series 916mm Diameter Single Sheave Pulley Block for Conductor Installation

Overview

The Stringing Machine Series 916mm Diameter Single Sheave Pulley Block is a vital tool used in overhead power line construction and conductor installation. Designed for smooth cable or conductor passage, this stringing pulley block ensures safety, efficiency, and stability during the stringing process. With a robust structure and precision-engineered sheave, it helps reduce conductor damage and friction loss during long-distance stringing operations.

Definition

A Single Sheave Stringing Pulley Block is a mechanical device used with stringing machines and tensioners to guide and support conductors or OPGW (Optical Ground Wire) during overhead line installation. The 916mm pulley diameter accommodates large-size conductors and ensures smooth running, even under high tension or heavy loads. It is an essential component in transmission line stringing equipment for electric power, communication, and railway electrification projects.

Features

High-Strength Material: The pulley frame is made of aluminum alloy or galvanized steel, providing lightweight durability and corrosion resistance.
Precision-Machined Sheave: The nylon or aluminum sheave offers excellent wear resistance and smooth rotation, minimizing conductor abrasion.
Sealed Ball Bearings: Ensure stable operation and long service life under tough field conditions.
Hook or Clevis Type Fittings: Suitable for various stringing configurations with hydraulic pullers and tensioners.
Safety Lock Design: Prevents accidental conductor release during installation.

Advantages

Smooth and Reliable Conductor Stringing: Reduces friction and prevents damage to expensive conductors and OPGW cables.
High Load Capacity: Engineered for heavy-duty transmission projects, ensuring performance under demanding field conditions.
Easy Handling and Installation: Lightweight yet strong, convenient for line workers to carry and mount.
Customizable Options: Available in different sheave materials, diameters, and configurations to match specific line stringing needs.
Cost-Effective and Long-Lasting: Offers long-term performance with minimal maintenance.

Application Fields

Overhead Transmission Line Construction
OPGW and ADSS Fiber Cable Stringing
Electrical Power Distribution Projects
Communication Cable Installation
Railway Electrification and Utility Pole Projects

Whether used with a hydraulic puller, tensioner, or stringing machine, this pulley block ensures safe, efficient, and precise conductor installation.
