About the product
Characteristics
Core Construction
-
Body Material: High-strength aluminium alloy — optimized for low weight and high durability.
-
Sheaves (Wheels): Stainless steel, mounted on sealed ball bearings for smooth, efficient rotation and reduced friction under load (improves performance on steel cable).
-
Color: Grey.
-
Origin: Manufactured in Taiwan.
Size & Weight
-
Overall Dimensions: 83 × 108 mm — durable size for cable applications.
-
Weight: Approximately 288 g (lightweight for its strength class).
Performance Ratings
-
Breaking Strength (Minimum): 20 kN — the force at which the pulley itself will fail.
-
Working Load Limit (WLL): Around 10 kN — safe service load for repeated use.
-
Compatible Cable/Rope Diameter: 9–12 mm — suited for most medium-diameter steel cables and ropes.
-
Maximum Recommended Speed: Up to 10 m/s — rated for higher-speed traverses like zip lines.
Standards & Reliability
-
Safety Standard: Certified to EN 12278, the European standard for pulleys — ensuring tested structural strength and performance.
-
Ball Bearings: Sealed bearings enhance performance accuracy and longevity, especially in dynamic use.
High-Efficiency Dual Sheave Design
-
The two sheaves (wheels) allow better alignment and load distribution — ideal for zip lines and complex pulley systems.
-
Ball bearing mounting ensures smooth rotation, reducing friction and making hauling or sliding loads easier and more efficient.
Durable & Purpose-Built
-
Stainless steel sheaves offer superior abrasion resistance compared to softer metals, especially when in contact with steel cable.
-
Aluminium body keeps the unit lightweight without compromising on structural integrity.
Versatile Rigging Component
-
Works with both steel cable and suitable ropes (within the compatible diameter range), giving flexibility across applications.
-
Construction and ratings make this pulley well-suited for professional rigging, aerial adventure setups, and technical hauling projects.
