In the global trailer industry, reliability and durability are more than just product features — they are essential requirements for safety and long-term performance. As a professional manufacturer specializing in trailer jacks and trailer accessories, Chenwei Machinery Manufacturing Co., Ltd. has been committed to providing high-quality trailer support solutions for customers worldwide.
With years of manufacturing experience, our company focuses on the design, production, and export of heavy duty trailer jacks, trailer support legs, trailer tongue jacks, RV trailer jacks, camper trailer jacks, trailer landing gear systems, and related trailer accessories. Our products are widely used in RV trailers, boat trailers, utility trailers, agricultural machinery, engineering equipment, and commercial transportation industries.
Chenwei Machinery Manufacturing Co., Ltd. was established with a clear mission: to provide durable, cost-effective, and reliable trailer jack systems for the global market. Over the years, we have successfully built long-term business relationships with customers from the United States, Europe, Mexico, Japan, and South Korea.
Our factory covers approximately 3,000 square meters and is equipped with complete production facilities, including:

By controlling the entire production process in-house, we can ensure product consistency, stable quality, competitive pricing, and efficient delivery times.
At present, our factory has a skilled production team and an experienced international sales department dedicated to supporting overseas distributors, wholesalers, OEM brands, and trailer manufacturers.
One of our most popular heavy duty trailer jack models is the 12000 lbs drop leg side wind trailer jack.
This model is specially designed for heavy-duty trailers and commercial applications. The drop leg structure allows users to quickly adjust height over a larger range, improving operational efficiency during trailer parking and loading.
Maximum capacity up to 12000 lbs
Heavy duty steel construction
Side wind handle for easier lifting
Stable drop leg design
Hot dip galvanized surface for corrosion resistance
Suitable for harsh outdoor environments
The jack is widely used in utility trailers, equipment trailers, agricultural trailers, and industrial transport systems.
The 8000 lbs square tube trailer jack is another highly demanded model in international markets.
Compared with traditional round tube designs, the square tube structure provides better stability and prevents unwanted rotation under heavy loads.
Compact structure
Detachable crank handle for security and convenient storage
Available in weld-on and bolt-on mounting types
Suitable for RV trailers, camper trailers, and boat trailers
Smooth lifting performance
This product is especially popular in North America and Europe.
For lightweight trailer applications, we also manufacture trailer jacks equipped with durable caster wheels.
These models are ideal for:
Small utility trailers
Household trailers
Small boat trailers
Mobile equipment platforms
The wheel design improves mobility and allows users to move trailers more conveniently on different surfaces.
All trailer jacks are manufactured using high-strength steel materials sourced from reliable suppliers. Every batch of raw materials undergoes strict inspection before entering production.
Critical components such as screws, gears, and lifting systems are processed using CNC equipment and precision thread rolling technology to ensure smooth operation and long service life.
Welding quality directly affects trailer jack safety and load-bearing capacity. Our factory uses CO2 shielded welding and automated welding equipment to guarantee strong and uniform weld seams.
We provide multiple surface treatment options including:
Hot dip galvanizing
Zinc plating
Powder coating
Black coating
Hot dip galvanized trailer jacks are especially suitable for marine and humid environments because of their excellent anti-rust performance.
Every trailer jack undergoes:
Manual operation testing
Load-bearing testing
Stability testing
Fatigue testing for selected models
Final appearance inspection
Only qualified products are approved for shipment.
