Fibre-rope crane lifts heavier loads for less

摘要

Fibre rope weighs very little in water, meaning that regardless of the length of rope paid out, no additional load is experienced by the crane. Wire rope, on the other hand, is heavier and so as more rope is paid out, the permissible load in relation to depth is reduced. A fibre-rope crane with a safe working load capacity of 150 tonnes can replace a wire-rope crane with a safe working load capacity of 250 tonnes when lifting at depths of 3,000 m and can continue to lift loads at even greater depths.
