The High Speed Turning Block is a heavy-duty cable pulling and conductor stringing tool designed to guide cables, conductors, and ropes through directional changes during installation. It is especially suitable for cable pulling operations where sharp bends, high pulling force, and long-distance routing may increase friction or cause cable jacket damage.
This turning block is available with rated loads from 50KN to 300KN, sheave diameters from Φ308mm to Φ916mm, and sheave widths from 75mm to 125mm. The steel sheave structure supports demanding field applications in transmission line construction, power cable installation, fiber optic deployment, and underground duct cable laying.
By providing a controlled cable turning path, the product helps reduce pulling friction, protect the cable surface at bends, and improve cable routing during construction.

The High Speed Turning Block is suitable for:
It is commonly used where cables or conductors need to change direction while maintaining a smoother pulling path.
50KN to 300KN Rated Load for Heavy-Duty Pulling
The product range covers 50KN, 80KN, 160KN, and 300KN rated load options, allowing selection according to different cable pulling or conductor stringing requirements.
Large Sheave Diameter for Cable Direction Control
With sheave diameters from Φ308mm to Φ916mm, the turning block provides a defined turning radius for cable and conductor routing, helping reduce stress at directional changes.
Steel Sheave for Field Construction Use
The steel sheave structure is suitable for demanding power construction environments where cable pulling tools need mechanical strength and wear resistance.
Helps Reduce Friction During Cable Pulling
The turning block guides the cable through bends, helping reduce friction compared with dragging cables directly across corners or rough surfaces.
Helps Prevent Cable Damage at Sharp Bends
When cables pass through sharp bends, jacket abrasion and bending stress may occur. This turning block provides a guided sheave path to help protect cable surfaces during installation.
Suitable for Multiple Cable Installation Projects
The product can be used in transmission line work, power cable laying, fiber optic cable deployment, and underground duct cable installation.
