50–100mm Inclined Double Bitt Bollard | CB/T 169-2011 Type A Welded Mooring Bollard for Ship Deck
Product Overview
CB/T 169-2011 Type A welded incline type bollard is designed for light-duty ship mooring applications.
The inclined double-post structure improves rope holding performance and prevents rope slipping during vessel movement.
It is suitable for workboats, barges and small vessels where compact and reliable mooring is required.
Quick Specifications

Engineering Design Logic
Load transfer path: Rope → Bollard Post → Base Plate → Deck.
Inclined posts increase friction and reduce rope slip.
Structure is optimized for light-duty mooring points.
Why Inclined Bollard Design?
Prevents rope slipping → Safer mooring
Improves holding → Stable rope control
Reduces accidental release → Reliable operation
Structure
Inclined posts | Top plate | Base plate | Rib plates | Welded structure
Custom Attributes
Inclined posts → Anti-slip performance
Compact base → Space saving
Smooth finish → Protects rope
Welded fabrication → Reliable strength
Selection Guide
Step 1 – Select A50 / A75 / A100 → Based on SWL
Step 2 – Confirm rope size → From table
Step 3 – Confirm installation → Deck welding
Step 4 – Confirm coating & certification

Inquiry Guide
Provide rope size, SWL, vessel type, quantity and certification.
How It Works
Rope wraps around inclined posts → friction increases → load transfers to deck → stable mooring.
Applications
Workboats | Small vessels | Barges | Harbor service ships
