Chain-on Tire Spades for Dual Tires: Improving Traction and Efficiency

[MikePhua]

When it comes to heavy equipment, especially in construction, agriculture, and mining, ensuring the best possible traction is critical for safety, productivity, and maintaining operational efficiency. One common solution for enhancing traction on vehicles with dual tires—such as loaders, graders, and trucks—is the use of chain-on tire spades. These are devices that help to improve the grip of dual tires, particularly in challenging terrain, without the need for full tire replacements or other costly modifications. This article explores the concept of chain-on tire spades, their purpose, benefits, installation, and when to use them.
What Are Chain-on Tire Spades?
Chain-on tire spades are chains that wrap around the tires of heavy equipment, providing additional surface contact for enhanced traction. Typically used on vehicles with dual tires (tires mounted side by side on the same axle), these spades serve to enhance grip on slippery, muddy, or otherwise unstable surfaces. The chains are often made from hardened steel or other durable materials, designed to withstand harsh conditions and provide long-term reliability.
The key difference between traditional tire chains and chain-on tire spades is the method of attachment. Chain-on tire spades attach to the outer side of the dual tires, forming a more secure fit and preventing the chains from shifting or becoming detached during operation.
Purpose and Functionality
The primary function of chain-on tire spades is to improve traction. Dual tires are often used on heavy equipment to distribute the load more evenly and prevent excessive wear on individual tires. However, dual tires can sometimes have reduced contact with the ground, especially in soft or slippery conditions. Chain-on tire spades work by creating additional points of contact with the ground, increasing friction and traction.
Here are some of the key reasons for using chain-on tire spades:

• Improved Traction on Slippery Surfaces: In snow, ice, or mud, traditional tires may struggle to maintain grip. The additional metal links in the chain-on tire spades help dig into the surface, offering better traction and reducing the likelihood of getting stuck.
  
• Enhanced Stability: On soft or uneven ground, the added traction provided by the chains can improve stability, preventing the equipment from sinking or tipping over.
  
• Load Distribution: The dual tire setup already helps distribute the weight of the vehicle, but chain-on tire spades can further assist by ensuring the weight is more evenly spread, preventing damage to the ground and the tires themselves.
  
• Cost-Effective Solution: Instead of investing in more expensive, specialized tires with built-in traction technology, operators can add chain-on tire spades to existing dual tires, improving their performance without a full replacement.
  

Types of Chain-on Tire Spades
There are various types of chain-on tire spades available, each designed for different applications. Some are made specifically for certain types of vehicles, while others are more universal. Here are a few common types:

• Cross-Link Chain Spades: These chains feature cross-links that form a grid over the surface of the tire. They provide excellent coverage and traction, making them ideal for vehicles operating in very soft or unstable terrain.
  
• Diamond-Link Chain Spades: These spades are designed with a diamond-shaped pattern that provides a balance between traction and comfort. They are suitable for use on snow, ice, and general muddy conditions.
  
• Bar-Link Chain Spades: These spades consist of long bar-shaped links that are designed for aggressive traction, ideal for vehicles working in rugged or heavily uneven conditions.
  
• Custom-Fit Chains: Some companies offer custom-made chain-on tire spades tailored to specific vehicles and tire sizes, ensuring a perfect fit and maximum efficiency.
  

Installation and Use
Installing chain-on tire spades is typically a straightforward process, but it does require careful attention to detail to ensure a secure fit. Here’s how the installation process generally works:

1. Choose the Right Size: Before installing chain-on tire spades, it’s important to select the correct size for your vehicle’s dual tires. Measure the tire size and consult the manufacturer’s guidelines to ensure compatibility.
   
2. Clean the Tires: Clean the tires thoroughly before installing the chain spades to remove any dirt, debris, or excess mud that could interfere with the installation.
   
3. Attach the Chains: Position the chain-on tire spades around the outer edge of the dual tires. Depending on the design, they may need to be draped over the tire or fed through designated slots on the tire. Some systems use tensioning devices to secure the chains tightly.
   
4. Check for Secure Fit: After installation, double-check that the chains are securely attached and evenly distributed across the tires. Tighten any tensioning devices if necessary.
   
5. Test the Equipment: Once installed, test the equipment at low speeds to ensure that the chains are functioning properly. Check for any signs of slippage or shifting.
   

Benefits of Chain-on Tire Spades
Chain-on tire spades offer several advantages for operators working in difficult conditions. Some of the main benefits include:

1. Improved Performance in Soft Terrain: Whether working on mud, snow, or loose gravel, chain-on tire spades can make a significant difference in performance. The added traction allows for better maneuverability and reduces the risk of the equipment getting bogged down.
   
2. Cost Efficiency: Instead of buying expensive tires with built-in traction, chain-on tire spades offer a budget-friendly solution that can be applied to existing tires, making them a great option for companies looking to reduce operational costs.
   
3. Longevity of Tires: By reducing tire slippage and improving traction, these spades help protect the tires from excessive wear. This can extend the life of the tires, leading to less frequent replacements.
   
4. Versatility: Chain-on tire spades can be used on various types of heavy equipment, including loaders, excavators, graders, and trucks, making them a versatile tool in the construction and agriculture industries.
   
5. Ease of Installation: Installing chain-on tire spades is a relatively simple process that can be done quickly and efficiently without the need for specialized tools or expertise.
   

Considerations and Limitations
While chain-on tire spades are highly effective in many situations, there are some limitations and considerations to keep in mind:

• Wear and Tear: Over time, the chains can wear out, especially when used on rough terrain. Regular maintenance and inspection are required to ensure they remain effective.
  
• Limited Effectiveness on Hard Surfaces: While these chains are excellent for soft ground conditions, they may not offer significant benefits on hard, compacted surfaces like pavement or concrete. For these conditions, alternative methods like rubber tracks or all-terrain tires may be more appropriate.
  
• Safety Concerns: Improper installation or use of chain-on tire spades can cause damage to both the tires and the equipment. Always ensure that the chains are securely fastened and avoid over-tightening, which could lead to stress on the tires or axles.
  
• Fuel Efficiency: The additional weight of the chains may slightly reduce fuel efficiency, as the vehicle has to work harder to move.
  

Conclusion
Chain-on tire spades for dual tires are a cost-effective, practical solution for improving traction in challenging conditions. They are widely used in industries such as construction, agriculture, and mining, where equipment must operate on soft, uneven, or slippery ground. By adding these chains, operators can enhance the stability and performance of their equipment without the need for costly tire replacements. However, as with any piece of equipment, it is essential to regularly inspect and maintain the chains to ensure optimal performance and avoid any potential issues down the road.
