Double Pulley Fiber Optical Cable Replacement Stringing Blocks
Product Overview
Double pulley fiber optical cable replacement stringing cradle blocks are designed for optical fiber cable replacement, OPGW stringing, ADSS cable installation and transmission line construction. With a 2kN rated load and lightweight double pulley structure, these stringing blocks provide stable cable guiding support during optical cable replacement work.
Two models are available: SH2-OPGW1 and SH2-OPGW2. The compact structure and light weight make them suitable for tower work, overhead line maintenance and field installation where easy carrying and quick operation are important.
Common Challenges
During fiber optical cable replacement and transmission line installation, contractors often face:
- Cable surface damage during pulling
- High friction during optical cable replacement
- Unstable cable movement on towers or crossarms
- Cable bending stress caused by unsuitable pulley structure
- Low efficiency when replacing OPGW or ADSS cables
- Difficult operation when tools are too heavy for tower work
Our Solution
The double pulley fiber optical cable replacement stringing cradle block solves these problems by:
- 2kN rated load for optical cable replacement and guiding work
- Double pulley structure for more stable cable movement
- Compact cradle design for OPGW and ADSS cable installation
- Lightweight 2.2-2.4kg body for easier tower operation
- Two model options for different working positions and site requirements
- Suitable design for transmission line installation and power line maintenance

How It Works
The fiber optical cable passes through the double pulley cradle block during replacement or stringing operation. The two-pulley structure supports and guides the cable more steadily than a single guiding point.
During pulling, the rotating pulleys help reduce friction and control cable movement. The cradle structure helps keep the optical cable in the correct position, reducing the risk of slipping, twisting or surface damage.
This design is especially suitable for OPGW and ADSS cable replacement projects where cable protection, stable guiding and lightweight operation are important.
Key Advantages
2kN Rated Load for Optical Cable Work: The 2kN rated load is suitable for fiber optical cable replacement, OPGW stringing and ADSS cable installation work.
Double Pulley Stable Guiding: The double pulley structure provides better cable support and improves stability during optical cable replacement.
Lightweight Tower Operation: With weights of only 2.4kg and 2.2kg, the blocks are easy to carry, install and operate during overhead line work.
Two Model Options: SH2-OPGW1 and SH2-OPGW2 are available to meet different installation positions and field working requirements.
Suitable for OPGW and ADSS: The cradle blocks are designed for OPGW cable replacement, ADSS installation and fiber optical cable pulling in transmission line projects.
Applications
This double pulley fiber optical cable replacement stringing cradle block is widely used for:
- Fiber optical cable replacement
- OPGW cable stringing
- ADSS cable installation
- Transmission line installation
- Power line construction
- Overhead communication cable installation
- Cable pulling and cable guiding work
- Tower maintenance and line replacement projects
Selection Guide
Based on model: Choose SH2-OPGW1 when the project requires model 20123 with dimension 152*110*343mm and weight 2.4kg. Choose SH2-OPGW2 when the project requires model 20124 with dimension 128*65*365mm and weight 2.2kg.
Based on cable type: For OPGW cable replacement, choose double pulley cradle blocks for stable cable guiding. For ADSS cable installation, choose lightweight structure for easier overhead operation. For general fiber optical cable replacement, choose the model according to tower position and installation space.
Based on operation requirement: For tower work, lightweight models are easier to carry and install. For cable replacement, double pulley design provides better cable stability. For long-distance pulling, multiple cable pulling blocks can be used together to reduce friction.
Based on rated load: Both SH2-OPGW1 and SH2-OPGW2 have 2kN rated load. The rated load should match the optical cable replacement requirement and site pulling tension.
