Oceanographic Blocks and Sheaves
Nylatron-sheave counterbalanced and fairlead blocks, instrumented blocks and aluminium snatch blocks designed to extend oceanographic cable life.
Description
General Oceanics blocks are designed to make cable last. NYLATRON sheaves, a high strength cast nylon containing molybdenum disulfide, reduce crown and cable wear and weigh one seventh of equivalent sized sheaves. Counterbalancing keeps the sheave coplanar with the cable regardless of ship roll, pitch and yaw during trawling and towing; fairlead (non-counterbalanced) versions reduce weight and height. Instrumented blocks provide remote reading of cable payout and rate, with Hydroblock readouts. Blocks meet the requirements of the Handbook of Oceanographic Winch, Wire and Cable Technology by Alan H. Driscoll.
