{"product_id":"njtx-167","title":"Aluminum Alloy 360° Universal Parallel Pulley Series","description":"\u003cp\u003eA 360° swivel parallel multi-sheave pulley designed specifically for heavy-duty rope rescue, hauling systems, and tripod\/multi-pod lifting systems. It supports the rapid setup of high-mechanical advantage systems such as 4:1 and 5:1, and is widely used for fine-tuning stretcher orientation, lifting and transferring heavy loads, and controlled lowering. The integrated 360° smooth-swivel top attachment point allows for self-adaptive orientation based on the hauling angle, effectively eliminating rope tangling, flange abrasion, and uneven loading when using parallel lines, significantly improving rope operation efficiency.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003e4:1 \/ 5:1 High-Advantage System Hub\u003c\/b\u003e: The parallel double and triple sheave structure allows ropes to enter and exit in parallel without overlapping, drastically reducing friction loss and simplifying the setup of high-advantage hauling systems.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003e360° Swivel Self-Adaptive Attachment\u003c\/b\u003e: The top swivel ring rotates instantly to align with the direction of the load, preventing rope twisting, edge abrasion, or jamming.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eVersatile Rescue Adaptation\u003c\/b\u003e: Highly suitable for fine-tuning the balance\/tilt of rescue stretchers, anchoring at the top of rescue tripods, and for the lifting and controlled lowering of heavy loads.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eHigh-Visibility Finish\u003c\/b\u003e: Features high-saturation, job-site identification colors (vibrant orange for the double pulley \/ bright yellow for the triple pulley) for rapid identification of sheave configuration in complex systems or low-light environments.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eRugged, Wear-Resistant Construction\u003c\/b\u003e: Precision-crafted from high-strength aluminum alloy, the body is impact-resistant and durable, ensuring smooth and stable performance under heavy lifting loads.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eComparison of Models and Applications\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003e[Parallel Double Pulley | Orange]\u003c\/b\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eStructural Features\u003c\/b\u003e: Parallel double sheave configuration; compact and agile design.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eRecommended Applications\u003c\/b\u003e: 4:1 mechanical advantage hauling systems, dual-point stretcher orientation control, and moving anchor redirection .\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003e[Parallel Triple Pulley | Yellow]\u003c\/b\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eStructural Features\u003c\/b\u003e: Parallel triple sheave configuration, providing additional rope pathways.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eRecommended Applications\u003c\/b\u003e: 5:1 or higher mechanical advantage heavy-duty hauling systems, single-point heavy lifting for deep-well\/high-altitude operations, and complex block-and-tackle hubs.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"NJTX","offers":[{"title":"Double Pulley - Orange (Suitable for 4:1 system)","offer_id":45810007081095,"sku":"J019","price":400.0,"currency_code":"HKD","in_stock":true},{"title":"Parallel Triple Pulley - Yellow (Suitable for 5:1 system)","offer_id":45829430870151,"sku":"J020","price":440.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/1740\/1991\/files\/Page14_Img12_IM233_50de4732-3cd6-4ff0-a532-ef189944ff95.jpg?v=1789033795","url":"https:\/\/treeholic.co\/en\/products\/njtx-167","provider":"Treeholic","version":"1.0","type":"link"}
