Once the linkage is disconnected, the brake bands can be removed. Depending on the machine design, the bands might be secured with bolts, nuts, or other fasteners. Carefully remove these fasteners using the appropriate tools, and then slide the brake bands off the drum or rotor.
After removing the brake bands, inspect the brake drum or rotor that the bands press against. Look for grooves, scoring, or other signs of damage that might prevent proper engagement of the brake bands.
If the brake bands are worn or damaged, replace them with new or refurbished bands. Ensure that the new brake bands are the correct size and type for the AT7C model.
Once the brake bands are installed, and the system is reassembled, it’s essential to test the turning brake system before resuming full operation.
To prolong the life of the turning brake bands and avoid frequent replacements, it’s essential to perform regular maintenance. Some helpful tips include:
The turning brake bands on the AT7C are vital for ensuring the machine's stability and maneuverability, particularly when operating in challenging conditions. By following a methodical process for removing, inspecting, and replacing the brake bands, operators can maintain their machines’ performance and extend the life of these crucial components. Regular maintenance and timely replacement of worn brake bands can significantly reduce downtime and improve overall machine safety.

The Role of Turning Brake Bands in the AT7C
In construction machinery like the AT7C, turning brakes are essential for allowing precise control during operation. The turning brake bands are typically part of a larger system known as the differential brake system, which is used to control the turning radius and improve the vehicle’s handling when turning.
- Function of Turning Brake Bands: Turning brake bands apply braking force to specific parts of the differential, typically to the outer or inner wheels during turns. When the machine turns, the brake bands engage and prevent the wheels from spinning at different rates, allowing for smoother turns and reducing the risk of wheel slippage.
- Importance in Operation: Turning brakes help maintain control over the vehicle in difficult conditions, such as on slopes or uneven terrain, where excessive wheel slip can cause the machine to lose traction. These components allow the machine operator to control the vehicle's speed and direction effectively while preserving the integrity of the other braking systems.
Turning brake bands can face a variety of problems during their operational life, with the most common being wear, misalignment, or damage. When these issues arise, the performance of the vehicle can be significantly impacted, potentially compromising safety.
- Wear and Tear: Over time, brake bands can become worn out from constant use, particularly in high-stress environments. This can lead to reduced braking efficiency, causing slower response times when engaging the brakes during turns.
- Brake Slippage: If the turning brake bands are not properly tensioned, the vehicle may experience brake slippage. This means the brake bands will fail to engage properly, causing the machine to continue turning even when the brake is applied.
- Damage or Fractures: The brake bands may develop cracks or fractures due to excessive strain or poor maintenance, leading to a complete loss of braking function.
