Early in the morning, a trailer factory in the American Midwest was just beginning its day's work.
A heavy-duty engineering trailer slowly pulled up, ready to be loaded with equipment. Workers skillfully cranked the side handle, and the 12,000-pound heavy-duty drop-leg trailer jack smoothly lowered, lifting the front of the trailer steadily – without any jerking or wobbling.
This is the most frequently overlooked, yet most crucial step in trailer operation.
Whether it's an RV, a boat trailer, or an engineering trailer, the **trailer tongue jack** is used repeatedly almost every day.
Its stability determines the safety of the trailer;
Its smoothness affects operational efficiency;
Its structural strength directly determines its service life.
And this is precisely what Chenwei Machinery has been focusing on for over a decade.
From the factory to real-world applications
Chenwei Machinery Manufacturing Co., Ltd. specializes in the design and manufacture of trailer tongue jacks and related trailer accessories.
We don't just "calculate load capacity" on paper; we repeatedly validate our products in real-world customer scenarios.
Take this 12,000-pound heavy-duty drop-leg side-crank trailer jack as an example:
High-strength steel main structure ensures stability even under full load.
Precision screw system makes lifting and lowering smooth and effortless.
Drop-leg design adapts to different heights and complex terrain.
Hot-dip galvanized surface treatment effectively resists rain, snow, salt spray, and humid environments.
Because of this, it is widely used in:
Engineering trailers, heavy equipment trailers, RV trailers, commercial trailers, and other applications.
More than just a product, but long-term reliable support
Many customers provide the same feedback after working with us:
"It's not the flashiest, but it's really sturdy and easy to use."
At Chenwei Machinery, we believe that trailer lift jacks, trailer jack stands, and trailer leveling jacks are not disposable consumables, but rather "essential components" that accompany trailers for the long term. Therefore, every jack undergoes the following tests before leaving the factory:
Manual operation test
Rated load test
Stability and durability check
All to ensure that when it is actually used, it will be a point of safety, not a point of risk.

Chenwei Machinery believes that:
Truly good products don't need exaggerated advertising;
