How Our Marine Mooring Consultancy Delivered Two Headfitt KSW300C-11/22 Swing Blocks to Scotland

When a Scottish harbour operator needed reliable mooring hardware for their operations, they turned to us. As specialists in marine mooring consultancy, we analysed their requirements, recommended the ideal solution and are now dispatching two Headfitt KSW300C-11/22 swing blocks with roller bearings.

You would use a roller-bearing block over a plain-bearing alternative when long service life, reduced rope wear and ease of operation are priorities. In confined quaysides or on deck, the compact swivel head of the KSW300C simplifies handling.  Being able to hook the rope over the roller, without having to feed the rope through the top of the roller is often needed.

What Is the Headfitt KSW300C-11/22 Swing Block?

The Headfitt KSW300C-11/22 is a heavy-duty mooring block engineered for high-load applications. Key specifications include:

• Working Load Limit (WLL): 11 tonnes
• Bearing type: Sealed roller bearings for minimised friction and extended service life
• Material: High-tensile steel with corrosion-resistant coating
• Swivel head fitting: Allows up to 360° rotation under load

We used a super green pin shackle and are supplying this fitted to the block.

Key Features and Benefits

• High Load Capacity
  • Supports lines or wire ropes up to 11 tonnes
  • Suitable for harsh tidal environments where peak loads occur during berthing or anchor handling
• Roller Bearing Design
  • Reduces operating friction by up to 70 per cent compared with plain bearings
  • Extends maintenance intervals by lowering wear on rope and block components
• Swivel Head Functionality
  • Eliminates line twist and reduces side-load stresses
  • Simplifies rigging adjustments during operations
• Durable Construction
  • Marine-grade coating protects against saltwater corrosion
  • Robust welds and bearing seals keep contaminants out

Typical Applications

You would specify a swing block of this class when:

• Mooring pilot boats, tugboats or ferries with dynamic multi-directional loads
• Anchor handling vessels requiring frequent reeving adjustments
• Offshore platforms needing high-efficiency fairleads to steer heavy mooring lines
• Cargo loading operations where line alignment must adapt to vessel movement
