Moving a Non-Running TD20E: Key Considerations and Methods

[MikePhua]

When dealing with heavy equipment like the International Harvester TD20E bulldozer, moving a non-running machine presents its own set of challenges. Whether you're transporting a machine across a job site, between locations, or for repair, the method chosen depends on several factors. These include the machine's condition, the terrain, available equipment, and the resources at hand. This article discusses how to safely and efficiently move a non-running TD20E, outlining potential solutions and methods for different scenarios.
Understanding the TD20E Bulldozer
The International Harvester TD20E is a robust crawler dozer that was widely used for heavy construction tasks such as land clearing, grading, and trenching. With a 6-cylinder diesel engine and a weight range of around 20-25 tons, it is designed for demanding tasks, and its size and weight can make moving it without operational power a complex issue.
The TD20E is equipped with a hydraulic system that powers the dozer blade and other components, but if the engine is non-operational, the hydraulic systems may not function, complicating tasks like steering, braking, and blade positioning. Hence, moving the machine without causing damage requires proper planning and specialized techniques.
Step 1: Assessing the Situation
Before attempting to move the non-running TD20E, it’s essential to understand the machine's condition. Key points to check include:

1. Engine Condition: Verify whether the engine has completely failed or if it can be temporarily restored to operation.
   
2. Hydraulic Functionality: Check if the hydraulics are still functional. If they are not, the blade and other components may remain fixed, limiting the machine's mobility.
   
3. Tracks and Undercarriage: Inspect the tracks, sprockets, and undercarriage for wear or damage. Non-running equipment may have additional wear if not properly stored.
   
4. Brakes: If the machine is going to be moved over any significant distance, understanding the brake condition is essential. If the brakes are non-functional, alternative methods for securing the machine during transit may be needed.
   
5. Towing Options: Determine whether the machine can be towed or if it will require a flatbed trailer or other transport methods.
   

Step 2: Manual or Powered Movement?
There are generally two primary approaches to moving a non-running bulldozer like the TD20E: manual movement or powered movement (if possible). The right choice depends on the specific condition of the machine.
Powered Movement
If the engine is still functional but the hydraulics or other systems are not, it might be possible to start the engine and use the tracks to drive the machine a short distance. However, in most cases of non-running machines, the engine won’t function, and the only viable option is to move the machine without power.
Manual Movement
If the machine is completely non-functional, or if you prefer not to risk further damage by trying to start the engine, manual methods will likely be required. These methods include:

1. Towing by Another Vehicle
   Towing a TD20E with another working vehicle, such as a larger bulldozer or a truck, is a common approach. To do this safely:
   • Secure the Tow: Use a strong tow rope or chain attached to a secure towing point. The TD20E has a heavy frame and requires a reliable anchor for towing.
     
   • Use a Tow Bar or Trailer Hitch: If possible, attach the machine to a tow bar or similar device. This reduces the risk of damaging the machine during the tow and allows better control over steering and stopping.
     
   • Slow and Steady Movement: When towing, always move slowly. Avoid sudden starts or stops, as they can cause damage to the tracks or frame.
     
2. Using a Lowboy Trailer
   For longer distances or when towing is impractical, using a lowboy trailer is often the best solution. Here’s how you can load the TD20E:
   • Loading the Machine: If the bulldozer can’t move under its own power, you’ll need a winch to pull it onto the trailer. A hydraulic winch, mounted on another machine, or a portable winch can be used to drag the dozer up the lowboy.
     
   • Secure the Machine: Once the machine is on the trailer, secure it with heavy-duty straps or chains to prevent shifting during transport. Ensure the straps are positioned correctly, securing the undercarriage and the frame without damaging the tracks.
     
   • Transport Considerations: Ensure that the route is accessible to a truck capable of hauling a heavy machine like the TD20E. Consider bridges, narrow roads, and other restrictions.
     

Step 3: Specialized Equipment for Transport
When the bulldozer must be moved across a long distance, relying on specialized equipment for loading, transport, and unloading is crucial. Some common methods include:

1. Hydraulic Winch or Rollback Tow Truck
   If the bulldozer is stuck in place, a hydraulic winch can be used to slowly pull it onto a flatbed or lowboy trailer. Rollback tow trucks are ideal for situations where the dozer can't be started and must be loaded onto a transport vehicle.
   
2. Tracked Transporters
   In cases where a more intricate transport solution is needed (such as navigating rough terrain or narrow spaces), tracked transporters (also known as tracked carriers or crawler transporters) can be used. These machines are designed to transport other heavy equipment, making them ideal for non-running dozers.
   

Step 4: Moving the Machine on Site
If the non-running TD20E is being moved on-site (rather than transported over long distances), there are additional considerations to make:

1. Level Terrain
   It’s much easier to move a dozer on level ground. If possible, try to move the machine across flat, stable surfaces to avoid tipping or getting stuck.
   
2. Use a Second Bulldozer or Skid Steer
   In some cases, using a second operational bulldozer or skid steer may help maneuver the non-running TD20E. The second machine can assist by pushing or pulling the TD20E to its destination, helping to overcome the lack of functional hydraulics or engine power.
   
3. Assistance from an Experienced Operator
   Moving heavy machinery, especially non-running equipment, requires experience to avoid accidents or equipment damage. It’s always advisable to have an experienced operator assist in planning and executing the movement.
   

Step 5: Final Check and Maintenance
After successfully moving the TD20E to its new location or transport vehicle, it’s crucial to conduct a thorough inspection. Check for any damage that may have occurred during the move, particularly around the undercarriage, tracks, and hydraulic system. If the machine is being transported for repairs, ensure that any loose parts are secured to avoid further issues during transport.
Additionally, if the TD20E is being moved for repairs or maintenance, it may be an ideal time to assess the condition of key components, such as the engine, transmission, and hydraulics. Scheduling necessary repairs before moving the machine again can prevent future difficulties.
Conclusion
Moving a non-running TD20E bulldozer requires careful consideration of the machine’s condition and the available resources. Whether you are towing it short distances or using specialized equipment for long-distance transport, the process demands attention to safety, the proper use of equipment, and, ideally, the assistance of skilled operators. By following the right steps, you can successfully move a non-running bulldozer with minimal risk of damage and ensure it reaches its destination safely, whether it’s for storage, repair, or further use.
