Multi-Groove Corner Ground Roller For Parallel Cable Pullin

The ​​Corner Ground Roller Tri-sheave​​ is a specialized cable handling device designed for directional changes during power line construction and cable installation projects. Featuring three independent sheaves in a triangular configuration, this professional-grade equipment ensures smooth cable transition around corners while minimizing friction and preventing conductor damage.

​​Construction & Design Features:​​

• ​​Sheave Configuration:​​ Three precision-machined sheaves at 120° angles
• ​​Frame Material:​​ High-strength galvanized steel or aircraft-grade aluminum
• ​​Bearing System:​​ Sealed ball bearings with grease fittings
• ​​Sheave Lining:​​ Replaceable nylon or polyurethane inserts
• ​​Load Capacity:​​ Rated for 4 tons (3.6 metric tons) working load
• ​​Safety Factor:​​ 4:1 minimum breaking strength
• ​​Mounting System:​​ Adjustable base for terrain adaptation

​​Performance Advantages:​​

• ​​Directional Control:​​ Maintains proper cable alignment during angle changes
• ​​Reduced Friction:​​ Independent sheave rotation minimizes pulling tension
• ​​Cable Protection:​​ Non-metallic lining prevents conductor damage
