Rugged Marine Performance: Anchor Boom Blocks

Anchor Boom Blocks (BBA Series) are heavy-duty rigging components engineered for specialized marine and anchor handling applications. These blocks feature a robust, shielded housing designed to protect the sheave and wire rope from impact and environmental damage during intense operations. Equipped with a swivel eye for natural load alignment, they provide reliable performance for working load limits ranging from 3.3 to 22.0 UStons.

Safety and Structural Durability
  • Structural Safety Factor: Every block is designed with a Minimum Ultimate Strength equal to four times the Working Load Limit (4 X WLL).
  • Head Fitting Rating: The Working Load Limit (WLL) is specifically rated based on the capacity of the head fitting.
  • Reliable Rotation: Sheaves are standard-fitted with bronze bushings for consistent operation in harsh conditions.
  • Safety Documentation: Comprehensive warning and safety information is provided on pages 136-145.
Advanced Technical Options
  • Enhanced Rotation: Units can be optionally supplied with a roller thrust bearing for the lifting eye to facilitate easier rotation under load.
  • Custom Wire Compatibility: The sheave groove can be precision-adjusted during manufacturing to accommodate various wire rope diameters.
  • Versatile Range: Standard models accommodate wire rope sizes from 3/8″ to 1 1/16″.
  • Broad Capacity Range: The BBA series offers solutions starting at 3.3 UStons and scaling up to 22.0 UStons.
