250KN T Head Cast Iron HT200 Cross Bitt Bollard Mooring Bitts Polished Ship docking

Material and Manufacturing:

Materials

● Cast Iron Main Body: Usually, HT200 gray cast iron is adopted. It has excellent casting properties, enabling the formation of complex T - shaped structures. It features good shock absorption, effectively absorbing the vibrations generated when a ship is moored. It also has certain wear resistance, capable of withstanding the friction of mooring ropes and the erosion of the external environment. Additionally, HT200 is relatively low - cost, allowing for cost control while ensuring performance.

● Anchor Bolts and Connectors: Anchor bolts generally use high - strength steel such as Q345 to ensure a stable connection with the cast - iron main body and reliably transfer the external forces received by the bollard to the foundation structure. Nuts and washers can be made of ordinary carbon steel or stainless steel. Ordinary carbon steel is used in general environments due to its low cost, while stainless steel is used in highly corrosive environments for its good corrosion resistance.

● Auxiliary Materials: Materials such as asphalt and fibers are often used as core fillers. They play a sealing role, preventing water and impurities from entering the interior of the bollard, which could lead to problems such as rusting. They can also act as a buffer when mooring a ship, reducing the friction between the mooring rope and the bollard, thus protecting both the rope and the bollard.

Manufacturing Process

● Mold Making: Based on the design dimensions and shape of the T-shaped cast iron bollard, materials such as wood, metal, or plastic are used to make the mold. For complex shapes, 3D printing can be employed to fabricate the mold, enhancing accuracy and production efficiency.

● Casting: Sand casting is adopted. The molten cast iron liquid is poured into the sand mold cavity, and after cooling and solidification, the casting is formed. Alternatively, lost foam casting can be chosen. After the model gasifies, the molten metal fills the cavity, enabling the production of castings with high dimensional accuracy and good surface quality.

● Machining: The cast blanks undergo turning processing. Areas such as the installation surface and mooring holes are treated to ensure dimensional accuracy. Drilling techniques are utilized to drill anchor rod installation holes, mooring holes, etc. at designated positions, ensuring the accuracy of the hole diameter and position. Milling processes are applied to process the surface and edges of the bollard, making them conform to the designed shape and roughness requirements.

● Surface Treatment: Shot blasting is commonly used to remove rust, molding sand, and impurities on the surface by the impact of projectiles, increasing surface adhesion. For painting treatment, anti - rust paint can be selected to form a protective film and prevent the cast iron from rusting. Galvanizing treatment can also be carried out to improve corrosion resistance, especially suitable for humid coastal environments.

Design and Structure

In the field of dock facilities, mooring bollards are key components to ensure the safe berthing of vessels. The rationality of their design and structure is of vital importance. Today, we are delighted to introduce the meticulously developed T-shaped cast iron mooring bollard, aiming to provide a more efficient and reliable mooring solution for port operations.

I. Design Concept

The design of the T-shaped cast iron bollard integrates advanced engineering mechanics principles and rich practical application experience to meet the complex and changeable operational requirements of modern ports. We are well aware that when ships are berthing, unberthing, or encountering severe weather, bollards need to withstand huge pulling forces and impact forces. Therefore, during the design process, we prioritize safety and stability. Through in - depth research on material properties and structural mechanics, we ensure that the bollard can maintain excellent performance under various working conditions, providing a solid guarantee for ship mooring.

II. Structural Components

1. Main Structure: It is made of high - quality cast iron material through elaborate casting and processing. The unique T - shaped design enables it to effectively disperse stress when under force, enhancing the overall structural stability. Compared with traditional mooring bollards, the T - shaped structure has higher strength and rigidity in resisting forces in horizontal and vertical directions, greatly reducing the risk of damage caused by uneven stress.

2. Anchor Bolts and Anchor Plates: These are key components for the tight connection between the mooring bollard and the wharf foundation. The anchor bolts are made of high - strength steel, featuring excellent tensile properties to ensure that the mooring bollard will not detach from the foundation when subjected to strong external forces. The anchor plates, through reasonable size design and optimized shape, increase the contact area with the foundation, effectively dispersing the forces transmitted by the mooring bollard and making the entire mooring system more stable.

3. Nuts and Washers: High - quality nuts and washers are selected to ensure the tightness and reliability of the connection. The precise processing of the nuts and their good thread fit can effectively prevent loosening, ensuring the stability of the mooring bollard during long - term use. The washers play a role in dispersing pressure and protecting the structural surface, extending the service life of the mooring bollard.

4. Core Filler: A special material is filled in the core part of the mooring bollard to further enhance its structural strength and impact resistance. This filler not only has good compressive resistance but can also absorb part of the impact force, reducing damage to the main structure of the mooring bollard and improving the reliability of the mooring bollard in harsh environments.

At our company, we are committed to providing our customers with the highest quality products and services. Our Mooring Bollards are no exception - they are designed to meet the highest standards of quality and reliability, ensuring that you get the best value for your money.

Installation and Maintenance:

Installation and Maintenance

1. Ultra - easy Installation: Determine the location based on the conditions of the wharf and ship berthing. Use a lifting device to hoist the mooring bollard to the installation point, align it with the anchor bolt holes for preliminary fixation. Then, use a spirit level to calibrate the verticality and tighten the bolts to complete the installation. The whole process requires no complex operations, saving labor and time costs.

2. Maintenance Suggestions: Conduct regular comprehensive inspections. Check whether there are cracks and deformations on the surface, and whether the anchor bolts are loose. If there are slight cracks or deformations, evaluate and repair them in a timely manner. If the bolts are loose, tighten them immediately to ensure the stability of the mooring bollard.

3. Good Daily Maintenance: Daily maintenance mainly focuses on anti - rust. Regularly clean the rust on the surface with a wire brush and then apply anti - rust paint. These simple steps can extend the service life of the mooring bollard and ensure that it always serves the port in its best condition.
