Product Description
100–320mm Four Roller Universal Fairlead | CB/T 3062 Type B Multi-Directional Mooring Fairlead for Ship Deck
Product Overview
CB/T 3062 Type B four roller universal fairlead is designed for multi-directional mooring rope guiding on ship decks.
The structure consists of two vertical and two horizontal rollers, allowing rope guidance from four directions with improved load distribution.
It is suitable for complex mooring conditions where rope direction varies, providing reduced rope wear and stable operation.
Engineering Insight (Why This Design)
In multi-direction mooring conditions, rope load is not evenly distributed.
Four roller configuration distributes load across multiple contact points, reducing localized stress and improving safety.
This design also minimizes rope bending and abrasion, extending service life.

Engineering Validation & Testing
Finite Element Analysis (FEA) is performed to verify structural strength and load distribution.
Load testing has been conducted on similar products to validate SWL performance.
Design and manufacturing comply with classification society requirements.

Fairlead Type Comparison
3 Roller Fairlead → Standard directional guiding for moderate load conditions
4 Roller Fairlead → Multi-direction guiding with better load distribution and reduced rope stress
Open Type Fairlead → Flexible rope entry, suitable for variable rope angles
Closed Type Fairlead → Controlled rope path, prevents rope escape under load
Selection Tip:
For complex mooring conditions or multi-direction rope leads, 4 roller fairlead is recommended.

Structural Optimization
Optimized lubrication system ensures smooth rotation and long-term operation.
Bush bearing design improves wear resistance and load transfer efficiency.
Pin shaft is designed as primary load-bearing component.
Material & Surface Options
Rollers can be manufactured in full stainless steel or stainless steel cladding for corrosion resistance.
Synthetic material protection layer can be added to rollers to reduce rope wear.
Ground smooth surface protects rope and improves service life.
Selection Guide
Step 1 – Select roller size → Based on rope diameter
Step 2 – Confirm rope type → Steel wire / synthetic
Step 3 – Confirm rope direction → Multi-direction requirement
Step 4 – Confirm load requirement → Refer SWL
Step 5 – Confirm installation location → Deck position
