Material and Manufacturing:

Materials

● Cast Iron: Generally, HT200 gray cast iron is selected. It has excellent casting properties, shock absorption, and wear resistance, enabling it to withstand the tensile force and impact when mooring ships. In some cases, ductile iron is also used. Ductile iron has higher strength and toughness than gray cast iron, which can extend the service life and reliability of the T - shaped cast - iron bollard.

● Anchor Bolts and Connecting Components: Anchor bolts usually adopt high - strength steel, such as Q345, etc., to ensure the connection strength with the wharf foundation. Nuts, washers, etc. generally use ordinary carbon steel or stainless steel to prevent rust and corrosion and ensure the long - term stability of the connection.

● Core Filler: Elastic materials such as rubber and polyurethane can be used as the core filler. When mooring ships, it can play a buffering role, protect the mooring ropes from wear, and also reduce the collision force between the ship and the bollard.

Manufacturing

● Mold Making: Corresponding molds are made according to the design dimensions and shape of the T-shaped cast iron bollard. Commonly used molds include wooden molds, metal molds, and plastic molds. For mass production, metal molds or plastic molds are generally adopted due to their high precision and long service life.

● Casting: Sand casting or lost foam casting is employed. In sand casting, the prepared molding sand is filled into the mold, compacted, and then the mold is removed to form the casting cavity. Subsequently, the molten cast iron is poured into the cavity. In lost foam casting, the foam plastic model is buried in dry sand. During casting, the foam plastic model gasifies and disappears, and the cast iron fills its position to form the casting.

● Machining: The cast bollard blank undergoes machining. This includes turning the outer circular surface of the bollard on a lathe to meet the designed dimensional and surface roughness requirements. A milling machine is used to mill the installation surface, mooring holes, etc., to ensure their flatness and perpendicularity. A drilling machine is utilized to drill the bolt installation holes and mooring holes on the bollard, ensuring the position and dimensional accuracy of the holes.

● Surface Treatment: Hot - dip galvanizing is a common treatment method. The bollard is immersed in molten zinc liquid, forming a uniform and dense zinc layer on its surface, effectively preventing corrosion. Spraying anti - corrosion paint is also an option. Epoxy zinc - rich paint, acrylic polyurethane paint, and other anti - corrosion paints are sprayed on the surface of the bollard to provide protection and decoration.

● Assembly: The processed bollard shell is assembled with components such as bolts, nuts, washers, and anchor plates. During assembly, first pass the bolt through the installation hole of the bollard shell, then put on the washer and nut on the bolt, and tighten the nut to firmly connect the bollard to the dock foundation. The core filler is evenly filled inside the bollard.

Design and Structure

In the current booming development of the water transportation industry, the safety and efficiency of ship berthing have become the core elements of port operations. To better meet the industry's needs, after a long period of meticulous research, development, and testing by our team, today, with great excitement and pride, we officially release the new T-shaped cast iron bollard. This product has achieved significant breakthroughs in both design concepts and structural construction, bringing unprecedented safety guarantees and convenient experiences to ship mooring.

Design Concept: People - oriented and Safety - first

1. Convenience - based Design for Practical Operations

We went deep into ports and docks, communicating closely with front - line crew members and dock workers to understand the problems they encountered in mooring operations. When using traditional bollards for mooring, crew members had to spend a significant amount of time and effort adjusting the position of the mooring ropes, and the operation was not very convenient. The unique T - shaped head design of the T - shaped cast iron bollard enables mooring ropes to be wound and fixed more easily, greatly shortening the time for mooring and unmooring. Taking a medium - sized cargo ship as an example, it takes an average of 15 minutes to complete the mooring operation using a traditional bollard, while with the T - shaped cast iron bollard, this time can be shortened to about 8 minutes, effectively improving the operational efficiency of the port.

2. Safety Considerations Throughout

When a ship is berthing, it is affected by various external forces such as wind, waves, and water currents. The bollard must have sufficient stability and strength to ensure the safety of the ship. The T - shaped cast iron bollard takes these factors fully into account in its design. By optimizing the structure, it can better distribute the tension generated during ship mooring. In the mooring test simulating strong typhoon weather, the T - shaped cast iron bollard withstood a tension of over 1000 kN and remained stable, while under the same conditions, some traditional bollards tilted or even broke.

Structural Analysis: Robust, Durable, and of Superior Quality

1. High - Quality Cast Iron Material
The T - shaped cast iron mooring bollard selects high - strength HT200 cast iron as the main material. This material has excellent strength and impact resistance, with a tensile strength of over 200MPa, which is much higher than that of ordinary cast iron. Meanwhile, it also has good corrosion resistance. Even under long - term seawater immersion and sea breeze erosion, it can still maintain stable performance, greatly extending the service life of the mooring bollard and reducing maintenance and replacement costs.

2. Scientific and Rational Component Composition

● Sturdy Shell: It adopts a thickened design, with the shell thickness increased by about 20% compared to ordinary mooring bollards. This enables it to effectively withstand the huge pulling force and impact force during ship mooring. The surface of the shell has undergone special anti - rust treatment, further enhancing its corrosion resistance.

● High - Strength Anchor Bolts: The anchor bolts penetrate deep into the wharf foundation and cooperate closely with nuts, washers, and anchor plates. The anchor bolts are made of high - strength alloy steel, with a yield strength of over 500MPa, ensuring that they will not loosen or break under various harsh working conditions and providing a solid guarantee for the stability of the mooring bollard.

● Anti - Loose Nuts and Thickened Washers: The anti - loose nuts are specially designed to effectively prevent the nuts from loosening due to vibration and shaking during ship mooring. The thickened washers increase the contact area and disperse the pressure, making the connection between the mooring bollard and the wharf foundation closer.

● Large - Sized Anchor Plates: The size of the anchor plates is about 30% larger than that of traditional mooring bollard anchor plates. This increases the contact area with the foundation, enabling it to better disperse the pulling force borne by the mooring bollard and effectively preventing the mooring bollard from being pulled out or displaced.

● High - Performance Core Fillers: The core fillers filled in the shell have good buffering and sealing properties. During ship mooring, they can absorb part of the impact force and reduce damage to the structure of the mooring bollard. At the same time, their good sealing performance effectively prevents seawater, impurities, etc. from entering the interior of the mooring bollard and protects the internal structure from corrosion.

3. Optimized Connection and Anchoring Methods
The connection between the anchor bolts and the wharf foundation adopts a new anchoring technology. Through special anchor固件 and grouting processes, the mooring bollard and the wharf foundation are integrated into a whole. This connection method greatly increases the connection strength between the mooring bollard and the wharf foundation. After actual tests, under extreme working conditions such as strong winds and huge waves, the connection between the T - shaped cast iron mooring bollard and the wharf foundation remains firm and reliable, ensuring the safe berthing of ships.

The launch of the T - shaped cast iron mooring bollard represents our deep understanding and active contribution to the development of the water transportation industry. We believe that with its innovative design concept and excellent structural performance, this product will become a powerful assistant for wharf operations, safeguard the safety of ship mooring, and help the water transportation industry reach new heights.
