Excavator Undercarriage Maximized Servicelife

Prolonged operation of an excavator can lead to chassis deformation. To address this excavator issue, you can use the following solution:

1. Chassis Alignment and Reinforcement

Check for chassis misalignment or deformation. If any issues are identified, it is important to align or replace the affected parts to ensure a stable base for the excavator.

2. Cross Braces Installation

To provide additional support and prevent further deformation, install cross braces at the location of the travel motors. These braces help distribute the weight and stress more evenly, reducing the chance of drifting. This measure directly responds to your requirement for adding lateral support to the travel motors.

3. Hydraulic System Check-up

Thorough inspection and maintenance of the hydraulic system, including the main pump, travel pedal valve, main valve, and travel motors. Ensure there are no leaks, blockages, or worn-out parts that could affect performance and cause drifting.

4. Pivot Point Lubrication

Lubricate the pivot points where the boom connects to the chassis. This can reduce friction and wear, helping to maintain proper alignment.

If your excavator tracks cannot turn left or right, it is generally due to severe wear on the distributor, causing pressure loss in the travel motor. This pressure loss prevents the tracks from turning. Rest assured, the hydraulic pump is not the issue. If the hydraulic pump were faulty or too small, you would also be unable to perform other excavation actions.

This problem may also be related to the hydraulic oil. If the hydraulic oil is not replaced on time, it can degrade and mix with impurities such as water, leading to emulsification and foaming. This can hinder normal operation and cause hydraulic components to rust.

Failure to replace hydraulic oil for an extended period can damage hydraulic parts, and the oil temperature may exceed normal levels. Fine hydraulic valves may frequently get stuck. And large hydraulic cylinders might overheat, causing cylinder damage.

Long-term neglect in replacing hydraulic oil can lead to oxidation, forming sludge at the bottom, rendering the oil unusable. If you have more questions about excavator operation or after-sales support, please feel free to contact us at any time.

If one side of the excavator track is not rotating, follow these steps:

1. Replace the key stock and reinstall it.

Try replacing the key stock and reinstalling it to see if that resolves the issue.

2. Consider replacing the travel motor.

If reinstalling the key stock does not solve the problem, it may be necessary to replace the travel motor with a new one. This is because the travel motor shaft is connected to the gear by a key stock. If the key stock breaks, it prevents the gear from being driven properly.

The main difference is where they work best. An off-road chassis is great for rough, tricky terrain. It can easily toss out anything caught in its tracks. It’s like a tank’s platform.

However, an engineering chassis usually does the job of dealing with less challenging situations. Our top recommendation is the engineering chassis. It can help your machine ensure a good balance of performance and practicality in regular situations.

Absolutely! YUFAN understands the importance of adaptability. Our standard machines are designed with your future upgrades in mind. We’ve incorporated a chassis expansion button on the control panel, allowing for potential modifications.

If you seek further customization or wish to explore detailed assembly specifications, feel free to reach out to our team. Our skilled engineering designers are ready to engage in discussions and tailor the design to your specific needs. Your excavator, your way!
