Double Sheave Stringing Block for 25-400mm Conductors with 5-20KN Load and Galvanized Steel Frame

Double Sheave Stringing Block 25-400mm for Small Conductor Crossarm Mounted Stringing

Product Overview

The Swerve Skyward Double Sheave Stringing Block is engineered for pulling small diameter conductors on crossarm mounted straight poles. Double sheave design provides enhanced stability and cable guidance for conductors from 25mm to 400mm. Available in 5KN to 20KN, sheave diameters 80mm or 120mm with 50mm or 60mm width. Frame from galvanized steel. Both aluminum alloy and MC nylon sheave options available.

Technical Specifications

Applications

· Pulling small diameter conductors on crossarm mounted straight poles

· Overhead transmission and distribution line construction

· Applications where maximum angle iron <90°

· Stringing requiring stable dual-sheave cable guidance

· Utility line maintenance and installation

Product Advantages

· Double Sheave Stability — Dual sheave provides superior cable guidance and stability, preventing conductor twisting during pulling operations.

· Ultra-Lightweight — Only 1.1-4KG, significantly reducing handling fatigue and simplifying installation at height.

· Wide Conductor Compatibility — Accommodates 25mm to 400mm conductors covering distribution and transmission applications.

· Ball Bearing Smooth Operation — Sealed ball bearings ensure low-friction rotation, reducing pulling force requirements.

· Dual Material Options — Aluminum sheave for durability; nylon sheave for superior cable protection.

· Galvanized Steel Frame — Hot-dip galvanized construction for excellent corrosion resistance.

Frequently Asked Questions (FAQ)

Q: Maximum angle?

A: Designed for max angle iron <90°. For larger angles, use our corner stringing block series.

Q: SHC vs SHCN difference?

A: SHC: aluminum sheave for durability. SHCN: MC nylon sheave, lighter and gentler cable handling.

Q: OPGW use?

A: Nylon sheave variants suitable for smaller OPGW. Consult our technical team.

Q: Mounting options?

A: Crossarm mounting on straight poles. Specify hanger type when ordering.

Q: MOQ?

A: Standard MOQ is 1 SET.
