Track Pad Folding for Shipping: Best Practices and Techniques

[MikePhua]

Introduction
Transporting heavy machinery such as track-type equipment (e.g., bulldozers, excavators) is a complex and meticulous process. One of the most critical aspects of preparing heavy equipment for shipping is managing the track pads. These large, rugged components are vital for mobility on rough terrain, but they present unique challenges when it comes to storage, transportation, and space efficiency. The practice of folding track pads for shipping is essential to ensure that machinery can be transported securely, safely, and within shipping constraints.
This article delves into the process of track pad folding for shipping, providing detailed insights into why it’s necessary, the techniques involved, and common issues that might arise during the preparation phase. It also highlights best practices, case studies, and expert tips for ensuring the machinery is ready for delivery.
Why Fold Track Pads for Shipping?
Track pads are the part of the machinery that makes contact with the ground, offering stability and traction. These pads, typically made of metal or rubber, vary in size depending on the machinery they are attached to. Due to their size and shape, track pads can take up a significant amount of space, which can complicate the transportation process.
Here are several reasons why track pad folding is essential for shipping:

1. Space Efficiency: Heavy equipment often needs to be loaded into shipping containers or onto flatbed trucks, and the track pads can be too wide or bulky to fit comfortably. By folding them, the footprint of the machine is reduced, making it easier to manage within the transportation space.
   
2. Safety: When track pads are left in their full operational position, they can create potential hazards during transport. They may catch on other equipment or be damaged when loading and unloading.
   
3. Cost Savings: Shipping costs are usually calculated based on the size and weight of the load. Folding the track pads minimizes the overall size of the equipment, leading to lower shipping costs.
   
4. Protection of Equipment: Folding the track pads helps ensure they don't get damaged during transport, as they are tucked away in a more compact position and are less prone to impact or abrasion.
   

The Track Pad Folding Process
Folding track pads for shipping is not a simple task, especially when dealing with large and heavy machines. The process requires specialized tools and equipment, as well as a detailed understanding of the machine's components. Here is an overview of the typical steps involved in folding track pads:

1. Preparation:
   • Before beginning the folding process, ensure that the equipment is parked on level ground and is properly secured.
     
   • Check that the tracks are clean and free of debris to prevent damage during the folding process.
     
   • Disconnect any power sources and hydraulics to avoid accidental activation during the process.
     
2. Removing Track Pins:
   • The first step in folding the track pads is to remove the track pins that hold the pads in place.
     
   • Specialized tools like track pin pullers are often required to remove these pins safely and efficiently. Make sure the correct size and type of pin puller are used to prevent damage.
     
3. Folding the Track Pads:
   • Once the pins are removed, the track pads can be folded inward. Depending on the equipment and the design of the track system, this process might involve manually rotating the pads or using hydraulic tools to adjust the track position.
     
   • In some cases, the tracks may need to be raised or lifted slightly to ensure that the pads fold in correctly without causing any damage to the undercarriage.
     
4. Securing the Folded Track Pads:
   • After the pads are folded, they should be secured in place to prevent them from shifting during transport.
     
   • This is typically done using heavy-duty straps or bolts that can hold the folded pads in a compact position.
     
   • It’s also essential to check the stability of the folded pads to ensure that they won’t loosen or move during transport.
     
5. Final Inspection:
   • Once the track pads are securely folded and locked into place, perform a final inspection of the equipment.
     
   • Check for any potential hazards, such as exposed sharp edges, loose parts, or any other issues that might arise during transit.
     

Challenges in Track Pad Folding for Shipping
While track pad folding is a necessary part of preparing heavy machinery for transport, it doesn’t come without its challenges. Below are some of the common obstacles operators and technicians may face during the process:

• Rust and Corrosion: Over time, track pins and other components can become corroded, making it difficult to remove them. In such cases, technicians may need to use specialized tools such as impact wrenches or even apply penetrating oil to loosen stubborn parts.
  
• Difficult or Stubborn Track Pads: Some track pads may be more difficult to fold due to their design or the condition of the machine. If the track pads have been heavily used or are particularly worn down, they may not fold as smoothly, leading to delays in the process.
  
• Weight and Size: The sheer weight and size of track pads make the folding process labor-intensive and require powerful equipment to assist in the process. The challenge of lifting and adjusting these large components can lead to safety concerns if not handled properly.
  

Case Study: Folding Track Pads for a CAT Bulldozer
In a recent case, a CAT D6 bulldozer was being prepared for international shipping. The equipment was undergoing transport from the United States to Europe, and the shipping company required that the track pads be folded to meet container size restrictions.
The bulldozer’s track pads were particularly large, and the removal of track pins required the use of a hydraulic track pin press to safely extract them without damaging the surrounding components. After removing the pins, the tracks were folded using a combination of manual effort and a hydraulic system to adjust the position of the track pads inward.
The folded track pads were then secured using heavy-duty ratchet straps, and the entire process was monitored by the technician to ensure that no component was at risk of being damaged during the procedure. After a final inspection, the bulldozer was successfully loaded onto the shipping container, with the folded track pads ensuring that the overall dimensions were within allowable shipping limits.
Best Practices for Folding Track Pads
Here are some best practices that experts follow when folding track pads for shipping:

• Use Proper Equipment: Ensure that the right tools are available, including track pin pullers, hydraulic equipment, and heavy-duty straps.
  
• Work in Pairs or Teams: Due to the size and weight of the components, having multiple people involved in the process is crucial to avoid accidents or injuries.
  
• Inspect Before and After: Always check the condition of the track pads and surrounding components before and after folding them to avoid any damage that could occur during the procedure.
  
• Consider Professional Help: For larger or more complex machinery, it might be worthwhile to hire professionals with experience in track pad folding to ensure the process is done safely and efficiently.
  

Conclusion
Track pad folding is a crucial part of preparing heavy machinery for transport. Whether it’s for international shipping or moving equipment between job sites, folding track pads ensures space efficiency, safety, and cost savings. While the process can be challenging, with the right tools and a systematic approach, operators can successfully fold track pads and prepare their equipment for shipping without compromising on safety or functionality.
By understanding the intricacies of the folding process and following best practices, operators can minimize the risk of damage during transport and ensure that the machinery reaches its destination in excellent condition.
