The excavator H-link, also known as the H-frame or H-connection, is a structural component of an excavator's arm assembly. It plays a crucial role in connecting the boom and the bucket or attachment to the excavator's mainframe.
The H-link is typically shaped like the letter "H" and is located near the base of the excavator's arm. It consists of two parallel, horizontal beams connected by a vertical beam in the center, resembling the letter "H." The horizontal beams extend outward and connect to the boom and the bucket or attachment mounting points.
The H-link serves several important functions:
1. Structural Support: The H-link provides structural strength and support to the excavator's arm assembly, helping to distribute the forces and loads encountered during digging, lifting, and other operating tasks.
2. Articulation: The H-link allows for the articulation or movement of the excavator's boom and bucket. It acts as a pivot point, enabling the bucket to tilt or curl, and the boom to raise or lower.
3. Attachment Connection: The H-link provides the attachment mounting points for connecting the bucket or other attachments to the excavator. These mounting points typically include pins, bushings, and other hardware that secure the attachment to the H-link.
The H-link is designed to withstand the stresses and forces encountered during excavator operations. It needs to be robust and durable to ensure reliable performance and longevity. The specific design and dimensions of the H-link can vary depending on the excavator model, manufacturer, and size class.
Overall, the excavator H-link is a critical component that facilitates the movement and connection of the boom and bucket, enabling the excavator to perform various digging, lifting, and material handling tasks.
Types of excavator H-links
The types of excavator H-links can vary based on the specific design and construction used by different manufacturers. While there may be variations in terminology and design, here are a few common types of excavator H-links:
1. Boxed H-Link: This type of H-link has a box-shaped design, where the horizontal beams and the vertical beam are made from thick steel plates welded together. It provides strength and rigidity to the arm assembly.
2. Fabricated H-Link: This type of H-link is constructed by welding together multiple steel plates to form the horizontal and vertical beams. It is a common design used in smaller excavators or for cost-effective manufacturing.
3. Cast H-Link: In this type, the H-link is cast as a single piece using molten metal, typically iron or steel. Cast H-links are known for their strength and durability, making them suitable for heavy-duty excavators and demanding applications.
4. Forged H-Link: This type of H-link is made by forging a solid piece of steel into the H-shaped structure. Forged H-links are known for their exceptional strength and resistance to wear and tear. They are commonly used in larger excavators and for heavy-duty operations.
It's important to note that different excavator manufacturers may have their own proprietary designs or variations on these basic types. The choice of H-link design depends on factors such as the excavator's size, operating conditions, and the manufacturer's engineering preferences.
When looking for specific types of H-links for a particular excavator model, it's best to consult the manufacturer's documentation, parts catalogs, or authorized dealers to ensure compatibility and proper fitment. They can provide accurate information regarding the suitable H-link options for your excavator.
Price for different excavator H-links
The pricing for different excavator H-links can vary based on various factors such as the specific excavator model, size, manufacturer, material, and market conditions. As I mentioned earlier, I don't have access to real-time pricing information since it can change over time.
To obtain accurate and up-to-date pricing for excavator H-links, it's best to contact authorized dealers, distributors, or manufacturers directly. They will be able to provide you with specific pricing details based on your requirements, including the excavator model and size, as well as any customization needs.
When reaching out to suppliers, it's helpful to provide them with the necessary details about your excavator, such as the make, model, and year of manufacture, to ensure they can provide you with accurate pricing information for the compatible H-links.
Here are some rough estimates:
1. Small to Medium Excavators (1-10 tons):
- Boxed H-Link: $500 to $1,500
- Fabricated H-Link: $400 to $1,200
2. Medium to Large Excavators (10-40 tons):
- Boxed H-Link: $1,200 to $3,000
- Fabricated H-Link: $800 to $2,000
- Cast or Forged H-Link: $2,000 to $5,000
3. Large Excavators (40+ tons):
- Boxed H-Link: $3,000 to $6,000
- Fabricated H-Link: $2,000 to $4,000
- Cast or Forged H-Link: $5,000 to $10,000
These price ranges are provided as rough estimates to give you a general idea. Actual prices may vary significantly depending on the factors mentioned earlier. It's always recommended to contact suppliers directly for accurate pricing information based on your specific excavator model and requirements.
