Blocks and Sheaves
General Oceanics blocks are designed to make your cable last.
Available sizes: .5M, 1M, 1.5M, 2M (sheave circumference)
- Increase Wire Rope Endurance Life
- Reduce Weight
- Corrosion Resistant
NYLATRON sheaves reduce crown and cable wear. Weight is one seventh (1/7) the weight of equivalent sized sheaves. NYLATRON is a high strength cast nylon containing fine particles of molybdenum disulfide (MoS2), a solid lubricant; the increased lubricity aids in extending cable life.
COUNTERBALANCING keeps the sheave coplanar with the cable regardless of ship roll, pitch, and yaw under trawling/towing operations.
Available configurations: Counterbalanced, fairlead (non-counterbalanced) for reduced overall weight and height. Instrumented blocks are used to provide remote reading of cable payout and rate.
Meets the requirements of “Handbook of Oceanographic Winch,
Wire and Cable Technology” by Alan H. Driscoll.
