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.

Main Technical Parameters (CB/T 169-2011 Type A)

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
