Elastic Wearlon sheaves take stress out of wire rope applications
Wire ropes used in a broad range of equipment – including lifting, winching and conveying applications – can benefit from durable sheaves and rollers (bottom right) made from engineered plastics, which protect against metal-to-metal contact and harsh abrasion from metal alternatives. Wire rope is integral to lifting, shifting and power transmission across a host of industries, starting with mining in the 1830s and extending since across wide swathes of industry. Uses today encompass cranes and lifting, cargo handling, elevators, construction, primary and food product harvesting, power generation technology (such as tendons in windmills), winching and conveying in manufacturing, minerals processing and materials handling and fixed and mobile plant used in paper and timber processing. Wire rope’s big initial advantage over the chains it originally replaced was that it would not snap catastrophically where there were flaws in chain links or solid bars, but rather individual strands could fail while others around them would take up the load safely and flexibly without shock. However, even the best quality wire rope will ultimately wear and potentially fail if it is subjected to constant abrasion, such as that induced by uneven metal-to-metal contact across sheaves and where lubricants attract grime to gradually compromise strength while attracting impurities into industrial processes. To help protect against such issues, Cut To Size Plastics custom-engineers sheaves and rollers for wire ropes using some of the world’s hardest-wearing engineering plastics, formulated to reduce wear and maintenance and enhance safety in a wide range of machinery and materials handling equipment. Examples of such sheaves are fabricated from Cut To Size’s internationally proven Wearlon range of hard-wearing cast polyamide engineering plastics, such as the LiNNOTAM products of the globally respected Licharz organisation. These products are formulated both for OEM use and metal replacement in applications involving transmission of mechanical force […]
