High Speed Turning Block: 300KN Heavy-Duty Single Steel Sheave for Conductor Stringing
Product Overview

The THZ series High Speed Turning Block is a professional-grade stringing tool designed for high-efficiency power construction. Engineered for steel wire rope traction, this block supports a maximum hauling speed of 80m/min and allows for the seamless passage of steel wire rope connectors. With a rated load capacity ranging from 50KN to 300KN, it is the ideal solution for complex turning angles in high-voltage transmission line projects.

Technical Specifications

Our turning blocks are constructed with reinforced steel sheaves to maintain stability under extreme tension:

Item Number Model Rated Load (KN) Sheave Diameter (mm) Sheave Width (mm) Weight (kg)
12141 THZ1-5 50 Φ308 75 22
12141A THZ1-8 80 Φ308 110 30
12142 THZ1-16 160 Φ600 110 115
12143 THZ1-30 300 Φ916 110 / 125 200
  • Maximum Allowable Speed: 80m/min
  • Sheave Material: High-strength Wear-resistant Steel
  • Compatible Media: Steel Wire Rope, Conductor, Fiber Optic Cable
Key Technical Advantages
  • Connector Pass-Through Design: Specially profiled sheave groove allows steel wire rope connectors to pass through without jamming, ensuring continuous operation.
  • High-Speed Stability: Optimized for hauling speeds up to 80m/min, significantly reducing project timelines compared to standard blocks.
  • Heavy-Load Durability: The full steel sheave and reinforced frame support up to 300KN (30 Tons), preventing deformation during high-tension turns.
  • Versatile Mounting: Equipped with a heavy-duty hanging eye for secure attachment in various field configurations.
Industrial Applications
  • Transmission Line Construction: Ideal for steering steel wire ropes during conductor stringing.
  • Long-Distance Traction: Used in hauling rope setups for fiber optic and overhead line deployment.
  • Complex Terrain Projects: Provides reliable turning points for traction systems in mountainous or restricted areas.
Professional Buyer FAQ
Q1: Can this block pass a standard steel wire rope connector?

Yes. The THZ series is specifically designed to allow high-speed passage of connectors, preventing manual intervention during the pulling process.

Q2: What is the maximum tension the THZ1-30 can handle?

The THZ1-30 is rated for a maximum load of 300KN, which is equivalent to 30 metric tons of pulling force.

Q3: Is the sheave material suitable for high-speed friction?

Absolutely. The sheaves are made of high-quality steel, designed to withstand the heat and friction generated at speeds up to 80m/min.
