Built for professional and technical rope applications, it supports fast, controlled travel while maintaining reliable performance under load.\u003c\/p\u003e\n\u003ch4\u003eHigh-efficiency design for traverses and highlines\u003c\/h4\u003e\n\u003cp\u003eThe Tandem Speed uses stainless steel sheaves mounted on sealed ball bearings to deliver excellent rolling efficiency. This construction supports smooth rope travel with minimal friction, making it well suited to long Tyroleans or tensioned systems where consistent movement is required. The pulley is rated for ropes up to 13 mm in diameter and achieves a stated efficiency of 95 percent, helping conserve energy across the system.\u003c\/p\u003e\n\u003ch4\u003eDurable construction with stable handling\u003c\/h4\u003e\n\u003cp\u003eStainless steel sheaves provide long-term durability and resistance to wear in demanding environments. The pulley is designed to accept up to three carabiners, which helps facilitate flexible system configuration and stable attachment during use. With a sheave diameter of 27.5 mm and a maximum allowable speed of 20 m\/s, it supports controlled, predictable travel across rope systems.\u003c\/p\u003e\n\u003ch4\u003eCertified performance for professional use\u003c\/h4\u003e\n\u003cp\u003eThe Petzl Tandem Speed Pulley has a maximum working load of 10 kN and is intended for technical rope setups where reliability and efficiency are critical. Weighing 270 g, it balances strength and robustness without unnecessary bulk. The pulley is certified to CE EN 12278 and UKCA standards, confirming suitability for professional rope access, rescue, and rigging applications where certified equipment is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDouble pulley designed for Tyroleans and tensioned highlines\u003c\/li\u003e\n\u003cli\u003eStainless steel sheaves for durability and long service life\u003c\/li\u003e\n\u003cli\u003eSealed ball bearings for smooth running and high efficiency\u003c\/li\u003e\n\u003cli\u003e95 percent stated efficiency to reduce friction\u003c\/li\u003e\n\u003cli\u003eAccepts up to three carabiners for flexible system setup\u003c\/li\u003e\n\u003cli\u003eCompatible with ropes up to 13 mm diameter\u003c\/li\u003e\n\u003cli\u003eMaximum working load of 10 kN\u003c\/li\u003e\n\u003cli\u003eCertified to CE EN 12278 and UKCA standards\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Petzl","offers":[{"title":"Default","offer_id":52574147903831,"sku":"P21SPE","price":50.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/0785\/8263\/files\/Petzl-Tandem-Speed-Pulley.jpg?v=1768802066","url":"https:\/\/treeworker.com\/products\/petzl-tandem-speed-pulley","provider":"www.treeworker.com","version":"1.0","type":"link"}
