Cast sheaves, rigging

Ropeblock self-lubricating cast sheaves are often applied in lifting, luffing and wire rope routing with intensive operating cycles. The groove opening angle was carefully designed to reduce potential twist resulting from fleet angles. In combination with the self-lubricating effect, the wire rope in your system will last longer. The latter was proved in recent research, in which several sheave materials where compared in terms of their effect on rope twist. It should come as no surprise that Ropeblock has been using these sheaves in most blocks for over 25 years. In most cases our standard sheaves can be fine-tuned to suit your application with only minor modifications.
