Whether you're into tree climbing (arborist work), setting up ziplines, rope rescue systems, or just need a serious pulley for heavy loads, this Lixada 30kN pulley is built to handle it. Rated for 30kN (that's about 6,700 pounds!), it's seriously strong stuff. Made from aluminum and magnesium alloy, it's lightweight (284g/10oz) but tough as nails. Handles ropes up to 13mm diameter and cables up to 12mm. Dimensions are 10.8x7.8x3.6cm (4.3x3.1x1.4in), color is blue. Comes brand new in original packaging with ASIN B097THNR27. UPC is 759974616679. The sheaves (wheels) run smoothly, reducing friction when you're pulling loads or setting up mechanical advantage systems. Perfect for professional arborists, adventure course builders, rescue teams, or serious outdoor enthusiasts who need reliable gear. Not for climbing protection (like ascenders/descenders) but fantastic for haul systems, rigging, or moving equipment. Always check your setup and use within rated limits, but this pulley gives you that professional-grade performance without breaking the bank. A versatile, strong piece of kit for anyone working with ropes and loads.
