Ropeblock sheaves promote wire rope longevity and prevent block rotation or cabling, leading to lower costs and higher crane uptime. They have proven themselves over twenty years of use in a wide range of applications. Ropeblock sheaves experience notably less wear than other materials due to their use of graphite, which reduces friction between the rope and sheave groove. They also perform well in low temperatures down to -40°C. Ropeblock B.V. is an engineering and manufacturing specialist that produces sheaves and other lifting components used globally in critical applications.
