Effectively and safely putting a trailer on jack stands involves a careful process of leveling, positioning, and securing the trailer to prevent accidental movement or collapse. This guide provides a step-by-step breakdown, ensuring you can confidently perform this essential maintenance task, whether you’re changing tires, performing undercarriage repairs, or simply storing your trailer for the off-season.
Why You Need Jack Stands for Your Trailer
Using jack stands isn’t merely a suggestion; it’s a crucial safety measure when working on your trailer. Relying solely on the trailer’s tongue jack or a single hydraulic jack is inherently unstable and poses a significant risk of collapse. Jack stands provide a stable and secure platform, distributing the trailer’s weight evenly and minimizing the risk of accidents. This is paramount, especially when you’re underneath the trailer. Additionally, jack stands are essential for long-term storage to prevent tire flat spotting and relieve stress on the suspension system.
Step-by-Step Guide to Placing Your Trailer on Jack Stands
This process assumes you are working on a relatively level surface. Minor adjustments can be made with leveling blocks under the tires if needed.
Step 1: Gather Your Supplies
Before you even think about lifting your trailer, make sure you have everything you need. This includes:
- Heavy-duty jack stands: Select stands rated for the weight of your trailer (or slightly more). Always prioritize higher capacity.
- Wheel chocks: Essential for preventing the trailer from rolling.
- Hydraulic jack: A bottle jack or floor jack appropriate for the trailer’s weight.
- Gloves: To protect your hands.
- Safety glasses: To protect your eyes from debris.
- Wood blocks (optional): For added stability and height if needed.
- Owner’s manual: Consult it for specific lifting points and safety recommendations.
Step 2: Prepare the Trailer and Work Area
Park your trailer on a level and solid surface. Engage the parking brake (if applicable) and securely chock the wheels on the opposite side of the trailer from where you’ll be working. This is a non-negotiable safety step. Clear the area of any obstructions and ensure you have adequate lighting.
Step 3: Locate the Proper Lifting Points
Consult your trailer’s owner’s manual or the manufacturer’s website to identify the designated lifting points. These are typically located on the trailer’s frame, near the axles. Using the wrong lifting point can damage the trailer. If you cannot find specific lifting point information, look for reinforced areas of the frame, ideally near axle mounting points.
Step 4: Position the Hydraulic Jack
Place the hydraulic jack under the designated lifting point. Ensure the jack is properly positioned and stable before proceeding. Double-check that the jack is making full, secure contact with the frame.
Step 5: Lift the Trailer
Slowly and steadily raise the trailer using the hydraulic jack. Lift only high enough to allow the jack stands to be placed underneath the frame. Avoid over-lifting, as this can create an unstable situation.
Step 6: Position and Secure the Jack Stands
Carefully position the jack stands under the frame, near the jack. Ensure the stands are on a solid surface and are fully supporting the weight of the trailer before removing the jack. Adjust the height of the jack stands to ensure they are securely supporting the frame. If using wood blocks, place them between the jack stand and the frame, not under the jack stand base.
Step 7: Repeat on the Other Side
Repeat steps 4-6 on the other side of the trailer, ensuring both sides are lifted evenly. It’s best to raise each side incrementally rather than lifting one side completely before the other. This prevents undue stress on the frame.
Step 8: Double-Check Stability
Before working on the trailer, thoroughly inspect the stability of the setup. Gently rock the trailer to ensure it is securely supported by the jack stands. If there’s any movement or instability, lower the trailer and reposition the jack stands. Once satisfied, give the trailer a good, solid shake to confirm stability before even thinking about crawling underneath.
Step 9: Lower the Jack
Once the trailer is securely resting on the jack stands, slowly lower the hydraulic jack until it is no longer supporting the weight. However, leave the jack in place, making light contact with the frame. This serves as a backup safety measure in case of jack stand failure.
Removing the Trailer from Jack Stands
The process of removing the trailer from jack stands is essentially the reverse of the installation process. Ensure the area is clear, position the jack under the lifting point, slowly raise the trailer slightly, remove the jack stands, and then carefully lower the trailer to the ground. Remember to remove the wheel chocks and store the jack stands properly.
Frequently Asked Questions (FAQs)
1. What type of jack stands should I use for my trailer?
Choose heavy-duty jack stands with a weight rating that exceeds the weight of your trailer (or a generous portion thereof). Consider the height range of the stands as well, ensuring they can lift your trailer high enough for your intended task. Look for stands made from durable materials like steel. Also, ensure they have a wide base for maximum stability.
2. Where are the best locations to place jack stands on my trailer?
Consult your trailer’s owner’s manual for specific recommendations. Generally, look for reinforced areas of the frame near the axles. Avoid placing jack stands on thin or unsupported sections of the frame.
3. Can I use cinder blocks instead of jack stands?
Never use cinder blocks as a substitute for jack stands. Cinder blocks are brittle and can crack or crumble under pressure, leading to a catastrophic failure. Always use properly rated jack stands.
4. How high should I lift my trailer?
Lift the trailer only as high as necessary to perform the required work. Over-lifting increases the risk of instability. The minimum safe height for access should be the goal.
5. Is it safe to work under a trailer supported only by jack stands?
While jack stands provide a secure platform, it’s always a good idea to take extra precautions. Consider using additional safety measures, such as placing the removed tires under the frame for added support. Never solely rely on jack stands without visual confirmation of their stability, a thorough shake test, and a backup plan.
6. How do I determine the weight of my trailer?
Check the trailer’s VIN plate or consult the manufacturer’s website for the GVWR (Gross Vehicle Weight Rating). This is the maximum weight the trailer is designed to carry.
7. What if I don’t have a level surface to work on?
Use leveling blocks under the tires to compensate for uneven surfaces. Ensure the blocks are properly sized and rated for the weight of the trailer. Start by parking the trailer with the wheels chocked, then use the blocks.
8. How often should I inspect my jack stands?
Inspect your jack stands before each use for signs of damage, such as cracks, rust, or bent components. Replace any damaged jack stands immediately.
9. What should I do if a jack stand fails while I’m working on the trailer?
If a jack stand fails, immediately evacuate the area. Do not attempt to repair or reposition the jack stand while the trailer is still supported. Lower the trailer to the ground using the hydraulic jack and assess the situation.
10. Can I use a single jack stand on one side of the trailer?
It’s generally not recommended to use a single jack stand on one side of the trailer, especially for any significant work. Using two jack stands provides a more stable and secure platform.
11. What is the best way to store my jack stands when not in use?
Store your jack stands in a dry and clean environment. Avoid exposing them to moisture or extreme temperatures. Lubricate the threads and moving parts periodically to prevent corrosion.
12. What if my trailer frame is rusted? Can I still use jack stands?
If your trailer frame is severely rusted, it may compromise its structural integrity. Have the frame inspected by a qualified professional before using jack stands. Rust can weaken the frame and make it unsafe to lift. In some cases, the frame may require repair or replacement.
By following these guidelines and taking the necessary precautions, you can safely and effectively put your trailer on jack stands for maintenance, repairs, or storage. Always prioritize safety and double-check your work to ensure a secure and stable setup.
