Accessing the Undercarriage of Tracked Skid Steers: Practical Solutions

[MikePhua]

Tracked skid steers, often referred to as track loaders, are invaluable machines for construction, landscaping, and agricultural work. Their ability to handle a variety of terrains, from soft soil to rough ground, makes them versatile. However, performing maintenance, inspections, or repairs on the undercarriage can be challenging due to their design. Accessing the underside of a tracked skid steer often requires specific equipment or techniques to ensure safe and efficient lifting. This article explores the different methods used to lift or drive a tracked skid steer to access its undercarriage and the advantages of each approach.
Importance of Undercarriage Maintenance
The undercarriage of a tracked skid steer is essential for its mobility and overall performance. It includes critical components like the tracks, rollers, sprockets, and idlers, which must be regularly inspected and maintained to avoid premature wear or failure. Given the tough conditions these machines often operate in, from muddy work sites to rocky terrains, the undercarriage is exposed to significant stress. Proper maintenance not only extends the machine's lifespan but also ensures operational efficiency and safety.
Challenges of Accessing the Undercarriage
Accessing the undercarriage of a tracked skid steer can be difficult because of the machine's low ground clearance and compact design. Unlike wheeled skid steers, which can simply be driven onto ramps or raised by a jack, the tracks of a tracked skid steer cover a significant portion of the machine's underside, limiting easy access.
Additionally, many operators prefer to inspect or repair the undercarriage themselves to reduce maintenance costs, but doing so requires specialized equipment or techniques to raise the machine safely. The following solutions are commonly used to overcome these challenges.
Methods for Accessing the Undercarriage

1. Using a Set of Ramps
   

One of the most common methods for accessing the underside of a tracked skid steer is by driving it onto a set of ramps. These ramps need to be sturdy enough to support the weight of the machine. Heavy-duty steel or aluminum ramps are recommended for this task. The machine is driven up the ramps, raising the undercarriage off the ground for easy access.
Pros:

• Simple and quick setup.
  
• Ideal for routine inspections or cleaning the undercarriage.
  
• No need for additional lifting equipment.
  

Cons:

• Ramps may not provide enough height for extensive repairs or detailed inspections.
  
• Requires a flat, solid surface for stability.
  
• Not always suitable for machines with very low ground clearance.
  

1. Hydraulic Lift Jacks
   

For more comprehensive maintenance or repairs, using hydraulic lift jacks is another effective method. A tracked skid steer can be lifted from the undercarriage using a hydraulic jack, either with a single jack or multiple jacks placed at key points. This method offers more control and precision when lifting the machine and can provide greater height than ramps.
Pros:

• Provides significant height and access for detailed work.
  
• Allows for more stable and controlled lifting.
  
• Suitable for a wide range of undercarriage repairs.
  

Cons:

• Requires proper training and knowledge of jack placement.
  
• May require additional safety equipment, such as jack stands, to prevent accidents.
  

1. Using a Lift Platform
   

For a safer and more reliable solution, some operators opt to use a lift platform or hydraulic lift table. These platforms allow the skid steer to be driven onto the lift, and then the platform can be raised to provide access to the undercarriage. This method is especially helpful for workers who need to perform repetitive undercarriage inspections or repairs on multiple machines.
Pros:

• Provides substantial height and full access to the undercarriage.
  
• More stable and safer than using jacks.
  
• Ideal for routine maintenance in fleet operations.
  

Cons:

• Expensive and may not be feasible for smaller operations.
  
• Requires a flat and level area to function correctly.
  

1. Pit or Raised Work Area
   

In some cases, operators may use a dedicated work pit or a raised platform. This method involves creating a recessed area in the ground or using a raised platform where the skid steer is driven onto. This method allows for easy access to the undercarriage without needing to lift the machine. It's a popular solution for facilities with a high volume of equipment maintenance.
Pros:

• Provides permanent access to the undercarriage, making maintenance easier.
  
• Ideal for shops that service a variety of heavy equipment.
  
• No need for ramps or lifting equipment.
  

Cons:

• Requires significant space and investment in the facility.
  
• Permanent installation may not be practical for all operators.
  

1. Using a Track Tensioner or Track Adjuster
   

For more specialized tasks, such as adjusting or maintaining the tracks themselves, a track tensioner or track adjuster may be used. These devices are designed specifically to relieve tension on the tracks, making it easier to inspect or replace them. Some track tensioners can also be used to raise the machine's rear end slightly, allowing for easier access to the undercarriage.
Pros:

• Specifically designed for maintaining or adjusting tracks.
  
• Can help relieve tension to make track work easier.
  
• Lightweight and portable.
  

Cons:

• Not suitable for lifting the entire machine off the ground.
  
• Requires proper handling and knowledge to avoid damaging the tracks.
  

Best Practices for Safety
Regardless of the method used to access the undercarriage, safety should always be a top priority. Here are some best practices:

• Use High-Quality Equipment: Ensure that ramps, jacks, and lift platforms are rated for the weight of the machine and are in good condition.
  
• Stabilize the Machine: If using jacks or a lift platform, make sure the skid steer is securely stabilized with safety supports or jack stands.
  
• Level Ground: Always work on level, solid ground to ensure that the machine remains stable during the process.
  
• Wear Protective Gear: Wear appropriate protective gear, including steel-toed boots, gloves, and eye protection, to minimize the risk of injury.
  
• Work with a Partner: If possible, have a second person available to assist with the process, especially when lifting or driving the machine onto ramps.
  

Conclusion
Accessing the undercarriage of a tracked skid steer is a vital part of maintenance, and choosing the right method to achieve this can significantly impact the safety and efficiency of the process. Whether using ramps, hydraulic jacks, a lift platform, or a pit, operators should select the method that best suits the type of work being performed and the available equipment.
By ensuring proper undercarriage maintenance, including regular inspections and timely repairs, operators can extend the lifespan of their tracked skid steers and ensure they remain reliable for tough jobs.
