JITAI
Crafted with a blend of high-strength aluminum alloy and MC nylon, the Stringing Block combines light weight with exceptional durability. The aluminum frame delivers rigidity and corrosion resistance, while the MC nylon sheave provides a smooth rolling surface that minimizes abrasion on cables.
The block can be supplied in hook type or joint plate type, offering flexible mounting options for different working environments. Each sheave runs on precision-sealed bearings, ensuring effortless rotation even under heavy load conditions.
In field operations, whether laying power lines over long spans or handling fiber optic cables in urban installations, this pulley guarantees efficient stringing with reduced manpower and safer cable handling.
Smooth Cable Handling:
The MC nylon sheave minimizes cable friction, extending wire life and maintaining insulation integrity.
Lightweight but Strong:
Aluminum alloy structure offers an excellent strength-to-weight ratio, simplifying transport and setup.
Multiple Configurations:
Single, 3-wheel, and 5-wheel models adapt to different conductor diameters and stringing conditions.
Flexible Suspension Options:
Available in hook or joint plate style for quick attachment to cross arms or anchors.
Corrosion & Weather Resistant:
Engineered for outdoor use, resistant to UV, moisture, and oxidation, suitable for harsh environments.
Labor & Time Saving:
Reduces physical strain during cable laying and enhances overall work efficiency.

Q1: Can this Stringing Block handle both aluminum and fiber optic cables?
Yes. The MC nylon sheave is gentle enough for fiber optic cables while strong enough for aluminum or steel conductors.
Q2: Are custom sizes or load ratings available?
Absolutely. We can manufacture stringing blocks based on your conductor diameter, weight, and stringing environment.
Q3: What’s the maximum load capacity?
Our standard models support from 10 kN to 20 kN, with heavy-duty versions available upon request.
Q4: How should I maintain the pulley?
Regularly check the bearings and ensure the sheave rotates freely. Apply light lubricant periodically for optimal performance.
Q5: What is the typical lead time?
For standard models, 7–15 days after order confirmation. Custom designs may require additional production time.
