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.
