How to Add Another Hydraulic Control to the Hough H-60: A Comprehensive Guide

[MikePhua]

The Hough H-60 is a versatile and durable piece of heavy equipment that has been a staple in construction and industrial applications for decades. One of the features that make the H-60 so useful is its hydraulic system, which powers various attachments and functions. However, as equipment needs evolve, there may be a requirement to add another hydraulic control to the system for additional attachments or improved operational flexibility.
This article provides a detailed guide on how to add another hydraulic control to the Hough H-60, covering the necessary steps, parts, and considerations for the modification. We’ll discuss the basic principles of hydraulic systems, the steps for adding a control, and some essential maintenance tips to ensure smooth operation.
Understanding Hydraulic Systems on the Hough H-60
Before diving into the steps for adding another hydraulic control, it’s important to understand how the existing hydraulic system works in the Hough H-60. Hydraulic systems in heavy equipment use fluid pressure to transfer power. In the case of the Hough H-60, the system is responsible for powering various functions such as lifting, tilting, and controlling attachments.
Hydraulic systems are typically powered by a hydraulic pump that draws fluid from a reservoir. The pressurized fluid then travels through hoses to control valves, which manage the flow of fluid to the necessary actuators or cylinders. Adding another hydraulic control means introducing a new valve or circuit that can be operated independently or in conjunction with existing controls.
Reasons for Adding Another Hydraulic Control
There are several reasons why an operator might want to add another hydraulic control to their Hough H-60. These include:

1. To Operate Additional Attachments: The Hough H-60 may be used with a variety of attachments like buckets, grapples, or hydraulic augers. If new attachments are added to the machine, they might require an additional hydraulic control to operate them effectively.
   
2. For Increased Flexibility: Sometimes, operators require more precision or the ability to control multiple functions simultaneously. Adding another control can help in improving the efficiency of work by allowing more flexibility with operations.
   
3. Upgrading for Enhanced Performance: Over time, the needs of a construction site can grow. By adding another hydraulic control, the machine can keep up with increased demands without the need to replace it with a newer model.
   

Planning the Modification: Key Considerations
Before proceeding with adding another hydraulic control, there are a few important factors to consider:
1. Hydraulic Flow Requirements
Ensure that the existing hydraulic system on the Hough H-60 has enough flow and pressure to accommodate the additional control. You’ll need to check the pump specifications, as some older models might not have sufficient capacity for additional controls. If necessary, upgrading the pump or adding a flow divider may be required.
2. Valve Selection
The new hydraulic control will require a valve to direct fluid to the new attachment. There are different types of valves available, including directional control valves, pressure relief valves, and flow control valves. Choose a valve that matches the specifications of the attachment you plan to use. Additionally, ensure the valve is compatible with the existing hydraulic system on your Hough H-60.
3. Hydraulic Hoses and Fittings
You’ll need to plan the routing of hydraulic hoses from the new valve to the actuator or attachment. Ensure that the hoses are the correct size and are rated for the pressures involved. Use appropriate quick couplers to allow for easy attachment and detachment of hydraulic equipment.
4. Integration with Existing Controls
Consider how the new hydraulic control will integrate with the existing controls. If your machine already has multiple hydraulic circuits, it may be beneficial to add the new control to the existing lever or joystick. Alternatively, a separate lever or switch might be necessary if more independent control is desired.
Step-by-Step Guide to Adding Another Hydraulic Control
Now that we understand the key considerations, let's break down the steps involved in adding another hydraulic control to the Hough H-60.
Step 1: Gather the Necessary Parts
To successfully add another hydraulic control to the Hough H-60, you will need the following parts:

• Hydraulic valve (directional control valve or multi-function valve)
  
• Hydraulic hoses and fittings
  
• Hydraulic pump (if required for more flow)
  
• Quick couplers
  
• Mounting brackets for the valve (if needed)
  
• T-connectors for the hydraulic lines
  
• Control lever or switch (if a new one is needed)
  

Ensure all parts are compatible with the Hough H-60 hydraulic system. Check manufacturer specifications for each part to ensure proper function.
Step 2: Locate the Hydraulic Pump and Reservoir
The first step in the modification is to identify the hydraulic pump and reservoir on the Hough H-60. Typically, the pump is driven by the engine, and the hydraulic fluid is stored in a tank or reservoir near the engine compartment. Ensure that the pump provides adequate pressure and flow for the additional control.
Step 3: Install the Hydraulic Valve
The next step is to install the hydraulic valve. Depending on the type of valve chosen, you will need to mount it in a location that is easily accessible for operation. The valve should be securely fixed to avoid movement during operation. In many cases, the valve is installed near the hydraulic reservoir or pump, making it easy to route hoses to the control valve and the attachment.
Step 4: Route the Hydraulic Lines
Once the valve is installed, you need to route the hydraulic hoses from the valve to the new attachment. Use T-connectors to tap into the existing hydraulic lines if the system supports this. Make sure the hoses are secure, well-protected, and do not interfere with any moving parts. You should also check that the hoses are rated for the correct pressure and are compatible with the attachment’s hydraulic requirements.
Step 5: Integrate the Control Lever
If you are adding a new control lever or switch, now is the time to install it. In some cases, the new control can be integrated with the existing joystick or lever. For machines with separate levers, the new control should be mounted securely within easy reach of the operator. Ensure that the lever or switch operates smoothly and doesn’t interfere with any existing controls.
Step 6: Test the System
Before you begin using the new hydraulic control, it’s crucial to test the system thoroughly. Start by checking all connections for leaks, ensuring that the new hydraulic lines are tight and secure. Run the system at low pressure initially, gradually increasing to full operating pressure. Test the attachment or actuator for smooth operation, and check for any unusual noise or performance issues.
Step 7: Adjust the System
Once the new control is operating properly, it may be necessary to make small adjustments. This could include fine-tuning the hydraulic pressure or flow to match the attachment’s requirements. Consult the operator’s manual for specific details on adjusting the flow settings and ensuring optimal performance.
Maintenance Tips for the Hough H-60 Hydraulic System
After adding another hydraulic control, it’s important to keep the system well-maintained to ensure long-term reliability and performance. Here are some key maintenance tips:

1. Check Fluid Levels Regularly: Ensure that the hydraulic fluid is at the correct level and is free from contaminants. Low fluid levels or dirty fluid can cause system malfunctions.
   
2. Inspect Hoses and Fittings: Regularly inspect the hydraulic hoses and fittings for any signs of wear, cracking, or leaks. Replace damaged hoses immediately to avoid failure.
   
3. Monitor Pressure Settings: Keep an eye on the hydraulic pressure to ensure that it remains within the manufacturer’s recommended range.
   
4. Clean Filters: Clean or replace the hydraulic filters regularly to maintain the health of the system.
   
5. Lubricate Components: Lubricate moving parts like the valve and actuator to prevent wear and ensure smooth operation.
   

Conclusion
Adding another hydraulic control to the Hough H-60 can significantly improve the versatility and functionality of the machine. Whether for operating additional attachments or increasing operational flexibility, this modification can help enhance productivity. By following the steps outlined in this guide and maintaining the system properly, you can ensure that the Hough H-60 continues to perform at its best, handling a wide variety of tasks with ease.
