Dual Use Stringing Block with Nylon Sheave for Transmission Line Construction

Product Introduction

The Sitting and Hanging Type Dual-Use Stringing Block is a versatile conductor guiding tool designed for overhead transmission line construction, conductor stringing, and power engineering installation.

This dual-purpose stringing pulley combines sitting installation and hanging installation methods, allowing flexible application according to different construction environments.

The stringing block adopts a nylon/composite sheave, steel support frame, and hook mounting structure, providing smooth conductor guidance and stable support during stringing operations.

It is widely used in transmission line projects where reliable conductor routing and flexible installation methods are required.

Product Features

Dual Installation Modes

The key feature of this product is its dual-use structure, which supports both:

• Sitting type installation
• Hanging type installation

This design allows operators to select a suitable mounting method according to site conditions.

Applications include:

• Tower structures
• Line angle sections
• Temporary conductor support points
• Different overhead line construction environments

Nylon Sheave for Smooth Conductor Guidance

The pulley uses a nylon/composite sheave that provides a smoother contact surface compared with metal-only structures.

Benefits include:

• Reduced conductor surface abrasion
• Smooth conductor movement during pulling
• Improved guidance performance during stringing operations

Hook Type Supporting Structure

The upper hook structure allows convenient suspension installation.

The design helps:

• Simplify field installation
• Adapt to different working positions
• Provide flexible conductor support solutions

Steel Frame Construction

The steel supporting frame provides mechanical stability for the pulley assembly.

Suitable for:

• Outdoor power line construction
• Transmission engineering projects
• Long-term field operation environments
