The O&K RH120E!

The O&K RH120E is a hydraulic excavator/shovel manufactured by Terex (formerly Orenstein & Koppel). Here are some key specs:

- Operating weight: around 120 tons
- Engine power: approximately 670-700 HP
- Bucket capacity: up to 6.5 cubic meters
- Reach: up to 19.5 meters

The RH120E is commonly used in mining, quarrying, and heavy construction applications.

Clean out the metal residue, which was likely causing the aeration and flow issues!

Now, regarding the lack of pressure, I'd like to help you explore some potential causes:

1. *Clogged or restricted hydraulic filters*: Even after cleaning the tank, there might be debris or contaminants in the filters that are restricting flow and pressure.
2. *Faulty or worn-out hydraulic pump*: The pump might be damaged or worn out, causing it to lose its ability to generate pressure.
3. *Incorrect hydraulic fluid viscosity or level*: Using the wrong type or viscosity of hydraulic fluid can affect the system's performance, including pressure. Also, low fluid levels can cause cavitation and loss of pressure.
4. *Clogged or blocked hydraulic lines or hoses*: There might be kinks, blockages, or damage to the hydraulic lines or hoses that are preventing the fluid from flowing properly and generating pressure.
5. *Faulty or malfunctioning hydraulic valves*: The valves might be stuck, faulty, or improperly adjusted, causing the system to lose pressure.
6. *System contamination*: Even after cleaning the tank, there might still be contaminants in the system that are affecting performance.
7. *Pump calibration or setting issues*: The pump might need to be recalibrated or adjusted to ensure proper pressure settings.

To help you troubleshoot further, can you please provide more information about your excavator's hydraulic system, such as:

- What type of hydraulic pump is used?
- What is the recommended hydraulic fluid viscosity and level?
- Have you checked the hydraulic filters and cleaned or replaced them as needed?
- Are there any other symptoms or issues you've noticed besides the lack of pressure?

Let's work together to identify the root cause of the issue and get your excavator's hydraulic system running smoothly again!
