5KN Rated Load Skyward Corner Stringing Block for Cable Jump-Out Prevention and Ultra-Lightweight Overhead Line Angle Tower Cable Pulling

5KN Skyward Corner Stringing Block for Overhead Line Angle Tower Cable Pulling

Product Overview

The Skyward Corner Stringing Block is a specialized tool for navigating corners, angles, and dead-end structures. Unlike standard blocks, it manages significant side pressures when a conductor changes direction. Deeper, more enclosed sheave prevents cable jump-out. Mounted on angle towers or dead-end structures, it guides cables smoothly around corners. Available with aluminum or MC nylon sheave, only 1.8-2.4kg.

Technical Specifications

Applications

· Navigating corners and dead-end structures in overhead line construction

· Mounting on angle towers for line direction changes

· Continuous pulling through corners without re-rigging

· OPGW and fiber optic cable installation at direction changes

· High-risk corner pulling requiring enhanced safety

Product Advantages

· Cable Jump-Out Prevention — Deeper enclosed sheave positively contains cable, preventing dangerous jump-out events at corners.

· Stress Reduction — Larger diameter sheave and smooth guiding path increase bend radius, distributing forces over greater cable length.

· Side Pressure Management — Reinforced side plates and high-grade alloy construction handle extreme redirected tension.

· Ultra-Lightweight — Only 1.8-2.4kg, much lighter than comparable corner blocks.

· Efficient Workflow — Enables continuous pulling through angles, saving time and labor.

· Durable Construction — Reinforced side plates and oversized bearings for reliable long-term performance.
