{"title":"Pulleys","description":"\u003cp\u003ePulley systems provide mechanical advantage for hauling loads, effecting rescues, and managing rope systems in climbing, canyoneering, and technical rope access applications where reducing effort or redirecting forces proves essential. Our collection of climbing pulleys includes single and multi-sheave designs, swivel configurations, and specialized rigging pulleys engineered for efficient rope management during big wall ascents, crevasse rescue, rope-intensive work positioning, and technical rescue operations requiring reliable mechanical advantage systems.\u003c\/p\u003e\n\u003cp\u003eClimbing pulleys reduce friction in rope systems through rotating sheaves that allow rope movement with minimal resistance compared to running rope directly through carabiners. Single-sheave rope pulleys suit basic hauling and directional changes, while double and triple-sheave models enable complex pulley systems generating 3:1, 5:1, or greater mechanical advantage ratios. Sealed bearing designs maximize efficiency, critical when hauling heavy loads on multi-day big wall climbs where every percentage of friction reduction eases workload.\u003c\/p\u003e\n\u003cp\u003eSelecting appropriate pulley systems requires understanding intended applications, rope diameters, and load requirements. Sheave diameter relative to rope size affects efficiency and rope longevity-larger sheaves reduce rope wear and friction. Working load limits must exceed anticipated forces with appropriate safety margins. Our climbing pulleys collection includes quality options supporting efficient rope management across diverse vertical environments and technical applications.\u003c\/p\u003e","products":[{"product_id":"edelrid-spoc","title":"Edelrid Spoc","description":"\u003cp\u003eUltra-light pulley with backstop.
