125–250 mm Inclined Double-Bitt Mooring Bollard | CB/T 169-2011 Type B Double-Base
Product Overview
CB/T 169-2011 Type B inclined double bitt bollard is designed for medium to heavy-duty ship mooring applications.
The inclined double-post structure increases friction and prevents rope slipping or accidental release during vessel movement.
It is widely used on cargo vessels, barges and harbor service ships requiring stable and high-load mooring performance.

Engineering Design Logic
Load transfer path: Rope → Bollard Posts → Base Plate → Deck Structure.
Inclined posts increase friction and reduce rope slip under dynamic vessel movement.
Double base plate improves load distribution and structural stability.
Why Inclined Bollard Design?
Prevents rope slipping → Higher mooring safety
Improves holding force → Better stability under vessel movement
Reduces accidental release → Safer operation
Suitable for dynamic conditions → Cargo vessels and barges
Structure
Inclined Double Posts | Double Base Plate | Reinforcement Plates | Welded Structure
Custom Attributes
Selection Guide
Step 1 – Select diameter → Based on rope size
Step 2 – Confirm rope type → Wire / fiber
Step 3 – Confirm load → Based on SWL
Step 4 – Select Type → Type B for heavy-duty application
Step 5 – Confirm certification requirement
Not sure about the correct model? Contact us — we will recommend the right solution based on your rope and working conditions.
Inquiry Guide
Please provide rope diameter, rope type, vessel type, installation position and certification requirement.
How It Works
Rope wraps around inclined posts → friction increases → load transfers to base → ensures secure mooring without slipping.
Applications
