MARINE CHOCKS & FAIRLEADERS OVERVIEW
Mooring chocks and marine fairleads may appear to be simple deck fittings, but they play an absolutely vital role in the safety and efficiency of any vessel or dock operation.
We offer a full spectrum of standardized and customized equipment:
Mooring Chocks: Including EU-Type, Panama Chocks (UL/ISO 13729 compliant), and Deck/Bulwark Mounted varieties.
Marine Fairleads: Featuring Roller Fairleads (2 to 10 rollers), Swivel Head Fairleads for offshore positioning, and Universal Fairleads for multi-directional tension management.
MARINE CHOCKS OVERVIEW
Mooring Chocks are reinforced openings installed on the bulwark or deck edge. Their primary function is to guide mooring ropes from the vessel to the dock while preventing the ropes from rubbing directly against sharp metal edges of the ship’s structure. Without properly designed chocks, mooring lines would quickly wear, fray, and fail — leading to vessels breaking free from their berths, colliding with docks or other ships, causing injuries, cargo damage, or environmental pollution.
MARINE FAIRLEADERS OVERVIEW
Marine Fairleads are more advanced than chocks. They incorporate rollers (horizontal, vertical, or both) that allow mooring lines to move freely with minimal friction. Fairleads are essential for large vessels, offshore platforms, and locations with significant tidal changes. By reducing friction, fairleads extend rope life, reduce crew workload, and allow mooring lines to self-adjust as the vessel rises and falls with the tide.
PRODUCTS SHOW
PANAMA CHOCK
A heavy-duty closed chock designed to meet Panama Canal regulations. It features reinforced construction and smooth rounded edges to guide mooring lines without cutting.
- Material: Cast steel (ZG230~450) or ductile iron
- Finish: Hot-dip galvanized or epoxy coating
- Safe working load (SWL): 50~150 tonnes
- Dimensions (opening size): 300mm × 200mm to 600mm × 400mm
- Weight: 50~300 kg
OPEN CHOCK
A U-shaped or C-shaped chock with an open top, allowing mooring ropes to be placed directly into the chock without threading through.
- Material: Cast steel,ductile iron,or stainless steel (SS316)
- Finish: Hot-dip galvanized,epoxy,or polished stainless steel
- Safe working load(SWL): 0~80 tonnes
- Dimensions (opening size): 150mm×150mm to 400mm×300mm
- Weight: 15~150 kg
CLOSED CHOCK
A fully enclosed ring-shaped chock. The rope must be threaded through the opening, but once in place, it is completely captive and cannot jump out.
- Material: Cast steel or ductile iron
- Finish: Hot-dip galvanized or epoxy coating
- Safe working load(SWL): 10~100 tonnes
- Dimensions (opening size): 100mm×100mm to 350mm×250mm
- Weight: 10~120kg
UNIVERSAL ROLLER FAIRLEAD
A multi-directional fairlead with both horizontal and vertical rollers, allowing mooring ropes to move freely in any direction with minimal friction.
- Frame Material: Cast steel, ductile iron, or stainless steel
- Roller material: Cast steel, stainless steel, or polyurethane
- Roller configuration: 2 horizontal + 2 vertical (2H+2V) or 3H+3V
- Finish: Hot-dip galvanized, epoxy, or polished
- Safe working load (SWL): 20 – 150 tonnes
- Dimensions (overall): 300mm × 300mm to 800mm × 600mm
- Weight: 50 – 400 kg
VERTICAL ROLLER FAIRLEAD
A fairlead with one or two vertical rollers. The rope passes against the roller face, reducing friction when the rope moves vertically (up and down).
- Frame material: Cast steel or stainless steel
- Roller material: Cast steel, stainless steel, or polyurethane
- Roller configuration: 1 or 2 vertical rollers
- Finish: Hot-dip galvanized or epoxy
- Safe working load (SWL): 10~80 tonnes
- Dimensions (overall): 200mm × 200mm to 500mm × 400mm
- Weight: 20~200 kg
