Universal Stringing Pulley Block For Overhead Power Transmission Line Stringing

The Model SH10TY Universal Stringing Pulley Block is a versatile and robust choice for overhead power line stringing, offering a good balance of strength, durability, and smooth operation.

Here are key recommendations and insights about the SH10TY Universal Stringing Pulley Block:

1. Durability and Materials

   • The SH10TY features pulley wheels made from aluminum alloy or MC nylon mounted on ball bearings, which ensures smooth rotation and reduces friction during cable stringing.

   • Its frame is constructed from high-quality steel with an anti-rust surface spray paint, enhancing corrosion resistance and longevity in outdoor environments.

   • This combination of materials makes it well-suited for demanding field conditions typical of power line installation.

2. Load Capacity and Specifications

   • The SH10TY has a rated load capacity of 10 kN (about 2,248 lbs), making it capable of handling medium to heavy cable loads during stringing operations.

   • The sheave diameter is approximately 178 mm by 76 mm, providing a good size for various cable diameters and minimizing cable wear.

   • Its weight is around 4.3 kg, which balances portability and sturdiness.

3. Versatility and Application

   • This block is described as "universal," meaning it can be used for a wide range of cable types and stringing scenarios, ideal for overhead power lines including ADSS and OPGW cables.

   • Its design allows easy integration with different rigging setups, making it a flexible tool for line stringers.

4. Advantages Compared to Other Stringing Blocks

   • Compared to lighter or smaller pulleys, the SH10TY offers a higher load rating and more robust construction, which is critical for safety and efficiency in power line work.

   • The use of ball bearings in the sheave reduces wear and operator effort, unlike some simpler pulley blocks that may have plain bushings.

   • Its anti-rust coating and steel frame provide better durability than many zinc-plated or plastic-framed blocks.

5. Considerations

   • While the SH10TY is strong and versatile, its weight (4.3 kg) is higher than some lightweight nylon or aluminum-only pulleys, which might be a factor if minimizing weight is critical.

   • The rated load of 10 kN is suitable for many but not all heavy stringing tasks; for extremely heavy cables or loads, higher-rated blocks might be necessary.

Summary

The Model SH10TY Universal Stringing Pulley Block stands out as a reliable, well-constructed choice for overhead cable stringing, combining durable materials, smooth operation, and a solid load rating. It is especially fitting for medium-duty power line projects requiring a universal, corrosion-resistant block with ball bearing sheaves. If your application demands a balance of strength, longevity, and ease of use, the SH10TY is an excellent option to consider.
