Jacking up a fifth wheel trailer is essential for maintenance, tire changes, or even winter storage, requiring a safe and methodical approach. This guide details the process, emphasizing safety precautions and proper techniques to ensure a stable and secure lift.
Understanding the Need for Lifting
Fifth wheel trailers, known for their size and weight, require specialized methods for lifting compared to smaller travel trailers. Regularly inspecting and maintaining your trailer involves accessing the undercarriage, which necessitates safely elevating it. Additionally, situations like flat tires on the road or the need for leveling on uneven terrain may demand immediate jacking procedures. Understanding proper weight distribution is paramount before any lifting commences.
Preparing for the Lift: Safety First
Safety is paramount when working with heavy machinery like a fifth wheel trailer. Neglecting precautions can lead to serious injury or damage to your equipment.
Safety Equipment Checklist
Before you even consider lifting your fifth wheel, gather the necessary safety equipment. This is not optional, and skipping steps can lead to catastrophic consequences.
- Heavy-duty jack: Choose a bottle jack or hydraulic jack with sufficient weight capacity for your trailer. Never exceed the jack’s rated capacity.
- Jack stands: These are absolutely essential! Jack stands provide secondary support and prevent the trailer from collapsing if the jack fails. Ensure they are rated for the appropriate weight.
- Wheel chocks: Place chocks behind the wheels opposite the side you are lifting to prevent the trailer from rolling.
- Gloves: Protect your hands from dirt, grease, and potential injury.
- Safety glasses: Prevent debris from entering your eyes.
- Level: Ensuring a level lift will contribute to safety and prevent unnecessary stress on the frame.
- Owner’s manual: Consult your trailer’s owner’s manual for specific jacking points and recommendations.
- Warning cones/triangles: If working on the side of the road, deploy warning devices to alert other drivers.
Choosing the Right Jack and Jack Stands
The weight rating of your jack and jack stands must exceed the weight of the trailer. Consult your trailer’s specifications to determine its weight. It’s always better to err on the side of caution and choose a jack and stands with a higher weight capacity. Consider the height of your trailer and choose a jack with adequate lift range to reach the jacking points. High-quality jack stands with a wide base and adjustable height are crucial for stability.
Identifying Jacking Points
Finding the correct jacking points is crucial for a safe and effective lift. Using improper locations can damage the trailer’s frame or suspension.
Consult Your Owner’s Manual
Your fifth wheel trailer’s owner’s manual is the definitive source for information on recommended jacking points. These points are typically reinforced sections of the frame designed to withstand the stress of lifting.
Inspect the Frame
If the owner’s manual is unavailable, carefully inspect the frame for reinforced areas near the axles. Look for solid, flat surfaces that can accommodate the jack’s base. Never jack on axles or suspension components, as this can cause severe damage. Avoid areas with wiring or plumbing. The frame will often have a small plate welded onto it indicating a designated jacking point.
The Lifting Process: A Step-by-Step Guide
With your safety equipment in place and the jacking points identified, you can proceed with lifting the fifth wheel. This process must be performed methodically and with constant vigilance.
Step 1: Chock the Wheels
Place wheel chocks securely behind the wheels on the opposite side of the trailer from where you will be lifting. Ensure the chocks are firmly in place to prevent any movement.
Step 2: Position the Jack
Carefully position the jack under the designated jacking point. Ensure the jack is stable and aligned properly. Use a small piece of wood, often called a jacking pad, between the jack and the frame to distribute the load and protect the frame’s finish.
Step 3: Raise the Trailer Gradually
Slowly and steadily raise the trailer with the jack. Monitor the jack’s stability and ensure the frame is lifting evenly. Avoid jerky movements, as this can destabilize the trailer.
Step 4: Position the Jack Stands
Once the trailer is raised to the desired height, carefully position the jack stands under the frame, as close to the jacking point as possible. Ensure the stands are securely placed on a solid surface.
Step 5: Lower the Trailer Onto the Jack Stands
Gradually lower the trailer onto the jack stands, ensuring they are bearing the weight properly. Never rely solely on the jack for support. The jack stands are the primary support while working underneath the trailer.
Step 6: Double-Check Stability
Before working under the trailer, vigorously shake the trailer to ensure it is stable on the jack stands. If there is any movement or instability, readjust the stands or add additional support.
Lowering the Trailer
Lowering the trailer is as important as lifting it. Reverse the process carefully, ensuring a smooth and controlled descent.
Step 1: Raise the Trailer Slightly
Use the jack to slightly raise the trailer off the jack stands.
Step 2: Remove the Jack Stands
Carefully remove the jack stands from under the frame.
Step 3: Lower the Trailer Slowly
Slowly and steadily lower the trailer with the jack. Monitor the descent and ensure the trailer is landing evenly.
Step 4: Remove the Wheel Chocks
Once the trailer is fully lowered and resting on its wheels, remove the wheel chocks.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions about jacking up a fifth wheel trailer:
-
Can I use the stabilizer jacks to lift the trailer for tire changes? No. Stabilizer jacks are designed to stabilize the trailer, not lift it. Using them for lifting can damage the jacks or the trailer’s frame.
-
What type of jack is best for a fifth wheel trailer? A bottle jack or hydraulic floor jack with sufficient weight capacity is recommended. Consider a high-lift jack for trailers with significant ground clearance.
-
How high should I lift the trailer? Lift it only as high as necessary to perform the required task, such as changing a tire or accessing the undercarriage. Excessive lifting can increase instability.
-
What if the ground is uneven? Use large, solid blocks of wood under the jack and jack stands to create a stable and level surface. Avoid using loose rocks or debris.
-
How often should I inspect my jack and jack stands? Regularly inspect your equipment for signs of wear, damage, or corrosion. Replace any damaged parts immediately.
-
Can I use a single jack stand? Always use at least two jack stands for safety. Never rely on a single stand to support the weight of the trailer.
-
What if the jack starts to leak fluid? Stop immediately and lower the trailer safely. A leaking jack is a sign of failure and should be replaced or repaired.
-
How do I know if the jacking point is strong enough? Look for reinforced areas of the frame or consult your owner’s manual. If unsure, consult a qualified RV technician.
-
Is it safe to work under the trailer if it is only supported by the jack? Absolutely not. Never work under the trailer unless it is securely supported by jack stands.
-
What size jack stands do I need? You need jack stands rated for at least one-half of your fifth wheel’s gross vehicle weight rating (GVWR) per stand. So, if your GVWR is 16,000 lbs, you need jack stands rated for at least 8,000 lbs each.
-
Can I use a scissor jack designed for cars? No. Scissor jacks typically lack the necessary weight capacity and stability for lifting a fifth wheel trailer. Use a jack specifically designed for heavy-duty applications.
-
What should I do if I am unsure about any part of the jacking process? Consult a qualified RV technician or experienced RV owner. Safety should always be your top priority.
Conclusion
Jacking up a fifth wheel trailer requires careful planning, the right equipment, and a commitment to safety. By following these steps and heeding the safety precautions outlined in this guide, you can confidently lift your trailer for maintenance, repairs, or storage, ensuring both your safety and the longevity of your valuable investment. Always remember that if you are at all unsure about any aspect of the process, consult a qualified professional.
