This <strong>friction system<\/strong> ensures smooth rotation and supports high loads without ball bearings. The cheeks are forged from <strong>hard anodized aluminum<\/strong>, which limits deformation under load and effectively protects the sheave. This material choice also provides <strong>good resistance to oxidation<\/strong>.<\/p>\n<p>The sheave is made from composite, resistant to corrosion. It operates without bearings, reducing maintenance needs and enhancing reliability in heavy-duty use. The overall design is optimized: the part&#8217;s mass is minimized without compromising mechanical strength. The model <strong>includes a swivel<\/strong> to allow the block to align freely under load.<\/p>\n<p>The block accommodates <strong>rope up to 16 mm in diameter<\/strong>. It is 191 mm long, weighs 915 g, and is fitted with a <strong>12 mm shackle<\/strong>. The maximum <strong>working load is 2750 kg<\/strong>, with a <strong>breaking load of 5500 kg<\/strong>.
