The CAT 980H is a large loader widely used in construction and mining industries. As a heavy-duty machine, the stability of its parking brake and hydraulic systems is critical to its work efficiency. When issues arise with the parking brake or hydraulic systems, timely diagnosis and repair can prevent equipment failure and ensure operational safety and performance.
Parking Brake Issues
The parking brake is a key system that keeps the equipment stationary, especially important when working on slopes or uneven terrain. The parking brake system of the CAT 980H is typically hydraulic, applying pressure to the brake pads against the brake disc to prevent the loader from moving. Common parking brake issues include:
The hydraulic system is essential for the operation of various functions in the CAT 980H, including bucket operation, steering, and lifting. Hydraulic system failure can significantly affect the overall performance of the machine. Common hydraulic issues include:
The proper functioning of the parking brake and hydraulic systems is crucial for the efficient operation of the CAT 980H loader. Timely diagnosis and repair of issues such as brake failure or low hydraulic pressure can help extend the machine's lifespan and improve work efficiency. Regular maintenance, including checking hydraulic oil and inspecting the brake system, is the best way to ensure the machine operates smoothly over the long term.

The parking brake system of the CAT 980H is typically hydraulic, applying pressure to the brake pads against the brake disc to prevent the loader from moving. Common parking brake issues include:
- Brake Failure: The brake is unable to fully lock, which can cause the equipment to move after being parked.
- Reduced Braking Efficiency: The brake feels loose during operation, and the braking effect is poor, possibly due to hydraulic oil leaks or insufficient pump pressure.
- Brake Pad Wear: Over time, brake pads wear down, causing a decrease in braking efficiency. Regular inspection and replacement are necessary.
The hydraulic system is essential for the operation of various functions in the CAT 980H, including bucket operation, steering, and lifting. Hydraulic system failure can significantly affect the overall performance of the machine. Common hydraulic issues include:
- Hydraulic Oil Leaks: Long-term use can lead to the aging or damage of hydraulic hoses, resulting in oil leaks, which reduce system pressure and efficiency.
- Hydraulic Pump Failure: If the hydraulic pump is damaged or deteriorates, it can cause low hydraulic pressure, impacting operation speed and precision.
- Hydraulic Oil Contamination: Using substandard hydraulic oil or failing to change the oil on time can lead to oil contamination, negatively impacting system performance.
- Check Hydraulic Oil: Ensure the hydraulic oil is of the correct quality and at the proper level. Regularly change the hydraulic oil and clean the filters to prevent contamination in the system.
- Inspect the Brake System: Check the hydraulic lines for leaks. Inspect the brake pads for wear, and replace them as needed.
- Maintain Hydraulic Pump and Hoses: Regularly inspect the hydraulic pump for proper operation. If you notice low pressure or unusual noise, repair or replace the pump. Also, inspect all hydraulic hoses for leaks or damage.
- Replace Damaged Parts: If the hydraulic pump, hoses, or brake components are severely damaged, they should be replaced promptly to avoid further damage and operational delays.
