Open-Sided Last Block: The Efficient & Convenient Solution for Final Conductor Sagging

As a prominent China manufacturer and exporter, Ningbo Changshi Electric Power Machinery Manufacturing Limited is dedicated to providing specialized equipment that makes every stage of power line construction more efficient. The Open-Sided Last Block for Conductor Tensioning is a perfect example of this. This innovative block is specifically designed for use as a "last block" at the end of a stringing run, where conductors are often "tightened up" and finalized for sagging. Its most significant feature is the "open side board," which allows the operator to easily and quickly place the conductor into the sheave without the need for complex threading. This unparalleled convenience makes it an indispensable tool for enhancing productivity and safety during the critical final stages of construction.

This last block is built on a foundation of robust and durable construction, ensuring it can handle the high tensions involved in conductor work. The secure latching mechanism on the side board guarantees the conductor remains safely in place during operation, while the heavy-duty sheave and frame provide a stable anchor point. The convenience of the open side not only saves valuable time but also reduces the physical effort required for rigging, making the entire process more manageable for your crew. By choosing this specialized, user-friendly tool, you are not just purchasing a block; you are investing in a solution that provides a substantial operational advantage in terms of both speed and ease of use.

Product Features & Benefits:

  • Open-Sided Design: The primary benefit is its side board that opens, allowing for quick, easy, and safe placement and removal of the conductor, drastically reducing setup and changeover time.

  • Designed for Final Tensioning: This block is purpose-built for the critical process of tightening and sagging conductors, making it an essential tool for the terminal stages of line construction.

  • Convenient & Easy to Use: The open-sided design eliminates the need for complex threading, making the block exceptionally easy to operate, even with heavy conductors.

  • Durable & Robust Construction: Built with a high-strength sheave and frame, the block is designed for long-term use and reliability in demanding outdoor environments.

  • Enhanced Worksite Efficiency: The combination of an open-sided design and a stable rigging point streamlines the tensioning process, leading to greater productivity and project completion speed.

Product Applications:

The open-sided last block is an essential tool for:

  • Final Conductor Sagging & Tensioning: The primary application for creating a secure rigging point for a puller or winch line to finalize the tension and sag of conductors at the end of a line section.

  • Dead-Ending Operations: Ideal for positioning conductors for dead-ending, as it allows for easy removal of the line from the block after tensioning is complete.

  • Re-conductoring Projects: A versatile and indispensable component for a wide range of tasks during line maintenance and re-conductoring operations where conductors need to be managed efficiently.

  • Any Rigging Point Requiring Access: Perfect for any situation where a quick-access sheave is needed for easy line placement.
