Product Description
80KN Ending Block: Heavy-Duty Terminal Conductor Stringing Block with Open Side Plate
Product Overview

The SH30J - SH80J series Ending Block is a specialized terminal pulley designed for the final stages of overhead power line construction. Specifically engineered to tighten up conductor wires, this block acts as the last pulley in the stringing sequence. Its robust steel construction and openable side plate design allow for rapid line insertion and removal, significantly improving operational efficiency in high-tension environments.

Technical Specifications

Our ending blocks are available in multiple load capacities to meet diverse transmission project requirements:

Item Number Model Rated Load (KN) Sheave Diameter (mm) Sheave Width (mm) Weight (kg)
12191 SH30J 30 KN Φ140 mm 36 mm 5.3 kg
12192 SH50J 50 KN Φ160 mm 48 mm 9.0 kg
12193 SH80J 80 KN Φ180 mm 56 mm 16.5 kg
  • Rotation: Silence Rotation System for smooth traction
  • Feature: Convenient Side Plate Opening mechanism
  • Material: High-strength Steel Sheave and Frame
Key Technical Advantages
  • Rapid Line Construction: The side plate can be opened easily, making it highly convenient for linemen to position the conductor during terminal tightening
  • High Tension Capacity: With a maximum rated load of 80KN, it provides superior reliability for heavy-duty conductor tensioning
  • Silence Rotation Technology: Built-in precision bearings ensure a "silence rotation" effect, reducing friction and extending the service life of the hauling rope
  • Durable Build: ISO9001 certified manufacturing ensures each block withstands harsh field conditions in power utility projects
Applications
  • Terminal Stringing: Used as the final block in the stringing sequence to finalize conductor tension
  • Conductor Tightening: Essential for adjusting sag and securing conductors at end-tower positions
  • Overhead Line Maintenance: Reliable tool for re-tensioning existing transmission lines
Professional Buyer FAQ
Q1: What is the main advantage of an "Ending Block" compared to standard stringing blocks?
The Ending Block is specifically designed for the tightening phase. The side-opening feature allows it to be installed or removed even when the conductor is already under partial tension, which is crucial for terminal tower operations.
Q2: Can the SH80J model handle ACSR conductors?
Yes, with a sheave width of 56mm and an 80KN load rating, it is suitable for various ACSR (Aluminum Conductor Steel Reinforced) sizes commonly used in high-voltage lines.
Q3: Is the sheave made of nylon or steel?
To handle the extreme pressures of terminal tightening (up to 80KN), these models utilize high-strength steel sheaves for maximum durability.
