How to Release the Brakes on a CAT 247B for Towing: A Step-by-Step Guide
#1
The CAT 247B skid steer loader is an essential piece of equipment used across a variety of industries, including construction, landscaping, and agriculture. While the 247B is known for its impressive versatility and power, there are certain situations where operators may need to tow the machine or move it when it’s not running. One of the most critical steps in this process is releasing the brakes, as the machine's parking brake system can prevent movement.
In this guide, we’ll walk you through the process of releasing the parking brake on a CAT 247B skid steer loader, provide troubleshooting tips, and offer advice for towing and transporting the machine safely.
Understanding the Parking Brake System on the CAT 247B
The CAT 247B uses a hydraulic parking brake system that is automatically engaged when the engine is turned off. This is a safety feature designed to prevent the machine from rolling unintentionally when parked. However, in certain situations, such as when towing the machine or moving it without power, it’s necessary to release the brake manually.
The parking brake on the 247B is typically released by using a manual release mechanism located on the machine. This system is designed to be simple and effective, allowing operators to disengage the brake when needed.
When Do You Need to Release the Brakes?
There are several reasons why you may need to release the parking brake on the CAT 247B:
  1. Towing the Skid Steer: If the machine is not running and you need to move it over a short distance, towing is the most viable option. Releasing the brakes ensures the wheels will rotate and the machine can be safely moved.
  2. Transporting the Machine: When loading the 247B onto a trailer for transportation, you may need to release the parking brake so the machine can roll onto the trailer without issue.
  3. Unresponsive Brake System: In rare cases, the parking brake may become stuck or malfunction, and releasing the brake manually may be necessary for recovery.
Steps to Release the Parking Brake on the CAT 247B
Releasing the parking brake on the CAT 247B is straightforward, but it’s important to follow the correct procedure to avoid causing damage to the brake system or any surrounding components. Here are the steps to follow:
  1. Locate the Manual Brake Release Valve
    The first step in releasing the parking brake is to locate the manual brake release valve. This valve is typically located near the back of the machine, near the hydraulic controls, or in the engine compartment. The exact location may vary depending on the model and year of the 247B, so consult the operator’s manual if you are unsure.
  2. Turn the Ignition Key to the "ON" Position
    Even though the machine is off, turning the ignition key to the "ON" position activates the hydraulic system, which may be necessary for releasing the brake. This is particularly important in machines where the hydraulic pressure is involved in the brake engagement process.
  3. Release the Parking Brake
    Using the manual release valve, disengage the brake. This may involve turning a knob, pulling a lever, or using a dedicated tool to release the brake. Depending on your model, you may need to apply slight pressure or release the valve to allow the brake to disengage fully.
  4. Test the Brake
    After releasing the brake, perform a quick check to ensure that the machine can move. You can do this by gently attempting to push or pull the machine (if on a flat surface). If the machine moves freely, the brake has been successfully released.
  5. Proceed with Towing or Transport
    Once the brake is released, you can safely tow or transport the CAT 247B as needed. Be sure to follow all safety precautions during transport, such as securing the machine to the trailer and ensuring that the towing equipment is rated for the weight of the skid steer.
Common Issues and Troubleshooting
While releasing the parking brake on the CAT 247B is usually a simple process, there are a few issues that could arise, especially if the brake system is malfunctioning. Here are some common problems and how to address them:
  1. Stuck or Malfunctioning Manual Release Valve
    If the manual release valve becomes stuck or doesn’t seem to disengage the brake, it could be a sign of wear or damage. In this case, applying a small amount of penetrating oil to the valve may help loosen it. If this doesn’t work, you may need to replace the valve or consult a technician.
  2. Hydraulic System Issues
    Since the parking brake system on the 247B is hydraulically operated, low hydraulic fluid levels or other issues with the hydraulic system can prevent the brake from releasing properly. Regularly check the hydraulic fluid and ensure there are no leaks in the system. If the brake fails to release even after using the manual valve, it may be time to inspect the hydraulic components.
  3. Brake Locking Up After Release
    If the parking brake appears to be released, but the machine still won't move, it could indicate that the brake is not fully disengaged or that there is another issue with the braking mechanism. In such cases, you may need to engage and disengage the brake multiple times or inspect the brake assembly for debris, corrosion, or other blockages.
  4. Power Loss During Towing
    In rare instances, if the machine’s power system is damaged or compromised, releasing the brake alone may not be enough to move the machine. In these situations, check for any damage to the engine, electrical components, or fuel system that could be causing the power loss.
Tips for Towing and Transporting the CAT 247B Safely
When towing or transporting the CAT 247B, it’s important to take safety precautions to avoid damaging the machine or compromising operator safety. Here are some tips to follow:
  1. Use Proper Towing Equipment: Ensure that the towing vehicle or trailer is properly rated to handle the weight of the 247B. Check for secure attachment points, and use quality straps or chains to ensure the machine stays in place during transport.
  2. Secure the Machine: Before transporting the 247B, ensure that it is properly secured to the trailer. Use heavy-duty straps or chains to tie down the machine, securing the tracks or wheels to prevent movement during transport.
  3. Check Terrain and Accessibility: Ensure that the area you are towing the machine through is free of obstacles and safe for movement. If towing over rough terrain, use appropriate equipment to guide the 247B and prevent additional strain on the system.
Real-World Example: Towing a CAT 247B to a Job Site
A construction company working on a large commercial project encountered an issue with their CAT 247B, where the machine’s engine failed before the job started. The operator needed to tow the machine to the site for repairs. After releasing the parking brake using the manual valve, the team was able to tow the machine to the repair area without further complications. They successfully used a flatbed trailer to transport the loader, securing it properly to avoid shifting. Once in the shop, they quickly diagnosed and replaced a faulty fuel pump, and the 247B was back in operation.
Conclusion: Safely Releasing the Parking Brake on the CAT 247B
Releasing the parking brake on the CAT 247B is an essential step for towing or moving the machine when it’s not running. By following the outlined steps and maintaining the brake system, operators can ensure safe and efficient transport of the machine. Regular checks on the hydraulic system, the manual release valve, and the overall brake components will help keep the system functioning properly and avoid any delays in case of emergencies.
Whether moving the machine for repairs or transporting it to a new job site, always take the time to follow proper safety procedures, check equipment conditions, and ensure that the machine is secure before towing. This proactive approach will help avoid unnecessary damage and keep the CAT 247B in prime operating condition.
