FTC Donut Rigging Ring / Pulley The FTC Donut Rigging Ring / Pulley is an innovative arborist rigging device that combines the functions of a large sheave pulley and a friction rigging ring in a single compact unit. Built for professional tree rigging, it supports lifting, lowering, redirects, and complex multi-rope systems while providing controlled friction and exceptional strength for demanding dismantling operations. Versatile rigging for simple and complex operations The Donut is designed to adapt to a wide range of rigging scenarios without the need for multiple specialist devices. The large sheave can be used for lifting or moving loads with minimal friction, while the central stainless steel ring provides controlled friction for lowering operations. Both sections can be used simultaneously, allowing two ropes to operate independently during complex rigging situations such as controlled load transfers or heavy sectional dismantling. High strength with lightweight construction Manufactured with hard anodised aluminium side plates and sheave alongside a stainless steel inner ring and spacers, the Donut combines durability with an excellent weight-to-performance ratio. Weighing just 1.6 kg, it offers a Working Load Limit of 80 kN through the sheave and 60 kN through the inner ring. It accommodates ropes up to 22 mm in diameter, or 14 mm when using a splice, making it suitable for a wide variety of professional rigging systems. Purpose-built for efficient arborist rigging Its compact circular design helps prevent incorrect positioning and reduces the risk of overhanging during installation. The symmetrical shape allows multiple rigging configurations using several slings or anchor points, including between two axes where positioning accuracy is important. Suitable for use both in the tree and at ground level as a redirect, the Donut delivers a practical solution for arborists seeking maximum versatility without increasing system complexity. Key Features Combined pulley and friction ring increases rigging versatility Supports simultaneous use with two independent ropes Large sheave provides efficient lifting and load movement Stainless steel inner ring delivers controlled rigging friction Compact round design reduces incorrect positioning Lightweight aluminium construction offers excellent strength Suitable for redirects and complex rigging configurations Accepts ropes up to 22 mm diameter or 14 mm with splice High Working Load Limits support demanding arborist rigging
