From Workshop to the World: The Story Behind Chenwei Trailer Jacks

In a small but highly efficient workshop, a simple question started everything:

“What makes a trailer jack truly reliable?”

For Renqiu Chenwei Machinery Manufacturing Co., Ltd., the answer was never just about lifting capacity.
It was about safety, durability, and trust.

Over the years, Chenwei has grown into a professional manufacturer specializing in trailer jacks, serving customers across the United States, Europe, and beyond. From everyday utility trailers to demanding applications like RV trailers, boat trailers, agricultural equipment, and heavy machinery, every product is built with one goal in mind:

To perform flawlessly when it matters most.

Built for Real-World Demands

One of our long-term customers in the United States once shared a challenge:

“We needed a jack that could handle heavy loads, resist corrosion, and still operate smoothly after years of outdoor use.”

That request led to the development of one of our most trusted models:

12000 lbs Drop Leg Side Wind Trailer Jack

Designed for heavy-duty applications, this model combines strength and flexibility:

• Drop leg design allows fast height adjustment

• Side wind handle ensures effortless operation

• High-strength steel structure provides exceptional stability

• Hot-dip galvanization protects against rust in harsh environments

Today, this model is widely used by trailer manufacturers and distributors across North America.

Practical Design for Everyday Use

Not every customer needs extreme load capacity—some need efficiency and versatility.

That’s where another popular model comes in:

8000 lbs Square Tube Trailer Jack with Detachable Handle

This jack is especially popular for boat trailers and RVs, offering:

• Square tube design for improved stability (no rotation under load)

• Detachable handle for easy storage and anti-theft protection

• Flexible installation options (bolt-on or weld-on)

It’s a perfect balance between performance and convenience.

Mobility Meets Simplicity

For lighter applications, customers often prefer flexibility over power.

Trailer Jack with Wheel

Equipped with durable rubber wheels, this type of jack is ideal for:

• Small trailers

• Personal boat trailers

• Home-use applications

It allows users to move trailers easily without heavy lifting, making everyday tasks much simpler.

Customization: Turning Ideas into Products

At Chenwei, we understand that no two customers are the same.

That’s why we offer full customization services, including:

• Structure: square tube, round tube, drop leg, swivel, etc.

• Load capacity: from 1,000 lbs to 12,000 lbs

• Surface treatment: powder coating, zinc plating, hot-dip galvanizing

• Height adjustment range

• Branding: logo, label, custom packaging

For OEM/ODM clients, we go even further—supporting design, sampling, and mold development, ensuring a smooth transition from concept to mass production.

Behind Every Jack: A Strict Manufacturing Process

Reliability doesn’t happen by accident—it’s built step by step.

1. Raw Material Control

We select high-quality steel that meets international standards.
Every batch undergoes hardness testing, dimension inspection, and anti-corrosion checks.

2. Precision Machining

Using CNC machines and advanced threading technology, we ensure smooth lifting performance and long service life.

3. Welding & Assembly

With CO₂ shielded welding and automated equipment, every joint is strong, uniform, and defect-free.

4. Surface Treatment

Options include:

• Hot-dip galvanizing (ideal for marine environments)

• Electro-galvanizing

• Powder coating

All processes meet ASTM and CE standards.

5. Testing & Inspection

Each trailer jack is tested for:

• Smooth operation

• Load capacity

• Structural stability

Some models undergo fatigue testing to simulate long-term use.

6. Packaging & Delivery

Products are packed using 5-layer cartons and pallet systems to ensure safe transportation.
Custom packaging is also available.

Proven in Global Markets

In the past few years, Chenwei trailer jacks have been exported to:

• United States

• Europe

• Mexico

• Japan

• South Korea

Each market has its own standards:

• USA: focus on heavy-duty performance and corrosion resistance

• Europe: higher requirements for appearance and environmental compliance

• Japan & Korea: precision and stability

• South America: cost-effective solutions

By adapting to these needs, we’ve built long-term partnerships with many trailer manufacturers and distributors worldwide.

More Than a Product — A Commitment

Customers often describe our products with three simple words:

“Strong. Reliable. Long-lasting.”

But behind those words is something deeper:

• Strict quality control

• Continuous design improvement

• Real understanding of customer needs

At Chenwei Machinery, we don’t just manufacture trailer jacks.
