ADI Casting Process

The process of manufacturing ADI is mainly divided into two steps:

• Casting ductile iron: First, the ductile iron casting is cast to control the chemical composition (such as the content of elements such as carbon, silicon, and manganese) and casting quality of the casting.
• Austenite step quenching: Ductile iron castings are quenched in the austenite temperature range and then kept warm to control the microstructure transformation. Through this process, ferrite is transformed into bainite, while spheroidal graphite remains in the iron matrix, which gives ADI unique mechanical properties.

Can I use ramps on uneven ground? How to use ramps on uneven ground?

Using ramps on uneven ground can be risky if not done correctly, but there are ways to safely use ramps in such situations by taking precautions. Here’s how to safely use ramps on uneven ground:

1. Assess the Ground:

  • Check for stability: Ensure the ground where you plan to set up the ramps is firm and stable. Avoid loose gravel, soft dirt, or areas prone to sinking.
  • Level the area as much as possible: If possible, use tools like a shovel or a leveling tool to create a more even surface for the ramp.

2. Use Adjustable or Telescoping Ramps:

  • Adjustable ramps: Some ramps are designed with adjustable legs or feet to accommodate uneven terrain. These ramps allow you to adjust the height on either side to create a stable surface for the vehicle or equipment.
  • Telescoping ramps: These ramps can extend to different lengths, giving you more flexibility in adjusting to uneven ground conditions.

3. Use Ramp Levelers or Blocks:

  • Ramp levelers: You can place specially designed leveling blocks or sturdy wooden boards under the low side of the ramp to raise it and create an even surface.
  • Stackable leveling blocks: These are made from durable plastic or rubber and are easy to adjust to different heights. They can help stabilize the ramp if one side is on higher or lower ground.

4. Secure the Ramps:

  • Anti-slip surfaces: Ensure the ramps have anti-slip surfaces or mats to prevent sliding, especially if the ground is sloped.
  • Tie-downs or straps: Use heavy-duty straps or chains to anchor the ramps in place, securing them to a stable object or the vehicle itself to prevent shifting during use.
  • Wheel chocks: Place chocks behind the wheels of any vehicle or equipment that is going up the ramps, especially on uneven or sloped terrain.

5. Place the Ramps on Firm Support:

  • Make sure both the top and bottom of the ramps are resting on firm, solid surfaces. Avoid placing the base of the ramp on soft or unstable ground that may shift under pressure.
  • Widen the base support if needed by using additional boards or other supportive materials to distribute the weight more evenly.

6. Use Caution While Loading/Unloading:

  • Slow and steady: When driving or pushing something up the ramp, move slowly and steadily to avoid sudden shifts in balance.
  • Avoid overloading: Ensure the weight on the ramp does not exceed its rated capacity, as uneven ground could increase the risk of collapse.
  • Spotter assistance: Have someone assist you as a spotter to help guide you and ensure the ramps remain stable while loading or unloading.

7. Alternative Ramps for Uneven Ground:

  • Folding or multi-panel ramps: Some ramps are designed with flexible joints that allow them to conform better to uneven terrain. These can provide more stability when compared to rigid ramps.
  • Traction ramps: Ramps with additional grip or cleated surfaces may work better on uneven ground as they provide better traction for both the vehicle and the ground.

8. Consider Ground Stabilization Options:

  • Gravel or Sandbags: Adding gravel or sandbags around the base of the ramp can help create a more stable foundation, particularly if the ground is prone to shifting.
  • Temporary ground mats: You can use ground protection mats to create a more even and solid surface for the ramps, especially on soft or muddy terrain.

9. Ramp Selection Tips for Uneven Ground:

  • Heavy-duty construction: For uneven ground, select ramps that are built to handle more strain and pressure, such as those made of reinforced aluminum or steel.
  • Wide ramps: Choose wider ramps to provide more surface area, increasing stability and reducing the chance of tipping or shifting.

Safety Tips:

  • Test stability: Before loading, test the ramp by applying slight pressure to ensure it’s firmly in place and won’t shift or slip.
  • Avoid steep angles: Ensure the incline is not too steep, as this increases the risk of accidents. If possible, lengthen the ramp to reduce the slope.
  • Inspect regularly: Check the ramp and any supporting materials for damage or wear, especially if they are frequently used on uneven ground.

By following these guidelines, you can safely use ramps on uneven ground while minimizing risks. However, it’s always important to prioritize safety and stability when dealing with uneven surfaces.

When using a car ramp, how should I position myself to ensure that the car can drive smoothly up the ramp?

To ensure the car drives smoothly up the car ramp, proper positioning is critical for both the car ramp and the vehicle. Here’s a step-by-step guide for safe and effective positioning:

1. Select a Flat, Stable Surface

  • Choose a level surface for setting up the car ramps. This ensures stability and prevents the car from rolling backward or shifting sideways while driving up the car ramps.

2. Align the Car Ramps with the Tires

  • Place the car ramps directly in front of the front tires (or rear tires if lifting the rear) and ensure they are aligned with the center of each tire. The ramps should be perfectly straight to avoid the vehicle slipping or sliding off.
  • Measure the width between the car ramps to match the distance between your car’s tires to avoid any misalignment.

3. Check Car Ramp Stability

  • Ensure the car ramps are securely placed and will not slide as the car begins to climb. Some car ramps come with non-slip bottoms; if yours don’t, consider placing a non-slip mat underneath them.

4. Drive Straight onto the Car Ramps

  • Sit in the driver’s seat and make sure you are facing the car ramps head-on. Slowly approach the ramps at a very low speed.
  • Go straight and steady—avoid any sudden acceleration or jerky movements. Stay centered on the car ramps at all times.

5. Use a Spotter if Possible

  • It’s helpful to have someone guide you from outside the car to ensure you’re aligned correctly as you drive up the ramps. They can help signal when you’re at the right position on the car ramp.

6. Watch for Car Ramp Markers

  • Many car ramps have a built-in stop at the top. When you reach this point, stop immediately to avoid driving off the ramp.

7. Apply the Parking Brake

  • Once the vehicle is fully on the car ramps, shift into park (or first gear if using a manual transmission), and apply the parking brake to prevent rolling.

8. Use Wheel Chocks for Extra Security

  • Place wheel chocks behind the rear tires (or front tires if lifting the rear) to ensure that the car remains stable and doesn’t roll off the car ramps.

By following these steps, you will ensure the car drives smoothly and safely up the car ramp. We are the first factory in China to produce this type of product.
