BEAL TRANSF'AIR 2B Swing-Sided Double Pulley (Ball Bearings)

• The TRANSF'AIR 2B is a piece of professional equipment featuring a double pulley with swing-open side plates, specifically designed for creating complex mechanical advantage systems (such as rescue hauling and heavy load lifting). It utilizes high-performance ball bearings to ensure maximum mechanical efficiency under heavy loads. Additionally, its wide structure accommodates larger diameter ropes, making it the preferred choice for professional rope access technicians and rescue teams.
• Top-tier Mechanical Efficiency: With an extreme efficiency rating of up to 93%, it minimizes friction loss during hauling, allowing technicians to move heavy loads with greater ease and efficiency.
• Professional Double-Pulley Structural Design: Engineered for setting up high-ratio mechanical advantage systems (such as 4:1 or 5:1), the double-pulley construction provides more stable load distribution and ensures the hauling process remains aligned.
• Swing-Open Side Plate Design: The pulley's side plates can be opened at any time, allowing for rapid installation at any point on the rope without the need to thread the rope through from the end, providing users with great flexibility and operational convenience. Compatible with O-shaped and D-shaped carabiners; not intended for use with steel cables to ensure correct equipment operation.
• High-Efficiency BALL BEARINGS: The internal assembly features stainless steel ball bearings and washers to ensure smooth operation and improved transmission efficiency, making it suitable for long-term heavy-duty tasks with excellent durability.
• Extensive Rope Diameter Compatibility: Supports professional ropes up to 16mm in diameter, offering high versatility for both traditional industrial rigging and large-scale mountain rescue scenarios.
• Lightweight Design: The side plates are made of aluminum alloy, providing excellent strength and durability while effectively reducing the total weight of the pulley for easy carrying and handling.
• Product Traceability: Each pulley has a unique idN identification number, facilitating equipment management and tracking, enhancing the product's professional standard and reliability.
• Certification: EN 12278:2007, CE.
