Product Description
20–200T Single Bitt Dock Bollard | Casting Steel & Ductile Iron Marine Mooring Equipment
Product Overview
The single bitt dock bollard is a heavy-duty marine mooring fitting designed for secure vessel berthing at ports, shipyards, and offshore structures. Manufactured from high-quality cast steel or ductile iron, it provides reliable performance under dynamic load conditions. Ductile iron offers superior wear resistance, while cast steel ensures high structural strength. All anchor bolts are hot-dip galvanized for enhanced corrosion resistance. Finite Element Analysis (FEA) is applied to verify structural integrity and optimize load distribution.
Quick Specifications
Capacity: 20–200 tons → Defines mooring load capacity
Material: Cast Steel / Ductile Iron → Strength vs wear resistance selection
Safety Factor: 3× → Ensures operational reliability
Cable Angle: Vertical -15° to +75°, Horizontal 0–180° → Flexible rope direction
Anchor Bolts: Hot-dip galvanized → Corrosion protection
Surface Treatment: Sa2.5 + Epoxy primer → Marine durability
