SD-DNV Series

The offshore SD-DNV series of man-rider winches are designed for general duty offshore use. Man-rider winches are classified for use where the load is used above the surface and below the surface (sub-sea). The sub-sea element is more stringent in load factors and material requirements. The winches are typically used on offshore cranes for manned baskets and for diving systems. The winch consists of a single hydraulic drive system with planetary gearbox, integral gearbox parking brake, dynamic hydraulic over-centre valve and an automatic emergency band brake. The winches are constructed from high quality Steel and painted with a Marine-Grade Primer and High-Gloss Topcoat. These winches are approved by classification societies.
