Strong structure 270° rotatable zinc alloy hooks and high-strength bolts provide stable load support and easy operation from multiple angles. High-strength ropes High-strength polyethylene ropes guided by multi-strand filaments deliver excellent tensile strength, abrasion and corrosion resistance, and a high loading capacity for safe, reliable operation. Long-lasting design Rust-resistant metal bearings and a galvanized housing protect the pulley block and positioning pulley system, delivering durable, long-lasting performance while resisting corrosion, wear, and fading. Low-friction roller The roller turns smoothly to minimize rope friction and reduce the risk of rope breakage under heavy or dynamic loads. Use scenarios - Construction and rigging: lift and position heavy components at various angles in tight or awkward spaces. - Industrial warehousing: move and align equipment or parts with confidence where space is limited. - Marine or yard operations: handle loads outdoors, where corrosion resistance and reliability are important.
