With over 10 years of industry experience, CHENWEI specializes in the design, development, and production of heavy-duty trailer jacks, serving customers across agricultural, industrial, and logistics sectors.

Premium Materials for Maximum Load Capacity

CHENWEI trailer jacks are manufactured using Q235B carbon structural steel and 45# high-carbon steel, delivering exceptional strength, weldability, and long-term reliability. The precision-machined screw rods support lifting capacities from 2,000 lbs to 12,000 lbs, making them ideal for both light-duty and heavy-duty trailer applications.

Custom-Engineered for Performance

Our in-house engineering team ensures that every component meets the highest standards:

• Nuts and gears are produced via powder metallurgy and enhanced through heat treatment for maximum wear resistance and smooth operation.

• Stamped parts are crafted with custom tooling, ensuring a perfect fit and enhanced mechanical strength.

• Available crank styles include side-wind and top-wind, with options for bolt-on or weld-on mounting to suit diverse trailer designs.

Advanced Manufacturing Process

At CHENWEI, we employ fully automated welding equipment to ensure consistent quality and structural integrity. For protection against harsh outdoor conditions, all trailer jacks are available with your choice of:

• Zinc plating (galvanizing) for superior corrosion resistance

• Powder coating for an enhanced, durable finish

These surface treatment options ensure long-term durability, even in the most challenging environments.
