What Makes Our Dual-Wheel Design Different?

You know the frustration when your jack sinks into soft ground. Our products solves that problem immediately.

The secret lies in the dual-wheel configuration. Two parallel wheels create double the surface contact area. This means your trailer stays level on sand, mud, or gravel. No more digging out stuck jacks on boat ramps.

Key Benefits You'll Notice Right Away:

· Superior weight distribution: Two wheels distribute load across a greater area.

· Simply pivot your caravan by hand without cleaning or binding.

· Performance is excellent on unpaved surfaces, grass, and soft soil.

· Weather and UV resistance: HDPE wheels last longer.

Think about how much easier your setup becomes. Park on grass at the campground? No problem. Launch your boat on a sandy beach? Done in seconds.

How We Manufacture Your Jack

At Qingdao RuiRui Machinofacture, we control every step of production.

Step 1: Precision CNC Machining

It takes our 20+ CNC tools just ±0.01 mm to cut and shape high-tensile steel. This makes sure that all the moving parts are perfectly lined up.

Step 2: Advanced Bending & Forming

The jack post and mounting parts are made with heavy-duty press brakes. Each turn is checked to make sure it is the right size.

Step 3: Professional Surface Treatment

To get ASTM B117 salt spray values of more than 500 hours, we use hot-dip galvanising or powder coating. In marine settings, your jack won't rust.

Step 4: Assembly & Testing

First article inspection (FAI) is done on every unit. Before sending, we check the finish quality, load capacity, and smoothness of rotation.

Where You'll Use This Equipment

Marine & Boat Trailers

Launching a 20-foot boat on a sandy ramp? The dual wheels prevent your jack from burying itself. Marina operators and weekend boaters rely on this design for quick, hassle-free launches.

Construction & Utility Trailers

Transporting heavy equipment to unpaved job sites? Your enclosed cargo trailer stays stable during uncoupling on muddy or graded terrain. No more dangerous tipping on uneven ground.

Agricultural & Livestock Transport

Horse floats and livestock trailers often park in grassy paddocks. Our Trailer Jack With Dual Wheels minimizes turf damage while keeping your trailer level. Retrieve your equipment easily, even after extended static storage.

Recreational Vehicles

RV owners love the stability when unhitching on campground grass or gravel sites. The wider footprint means you can set up camp without worrying about jack failure.

Understanding the Mechanism

Your product uses precision engineering to make heavy lifting effortless.

The ACME screw mechanism converts rotational force into vertical lift. Advanced models include side-wind handles with geared ratios to reduce cranking effort.

Grease zerks allow easy lubrication of moving parts. Regular maintenance keeps the internal screw and pivot pins operating smoothly.

The dual-wheel assembly rotates 360 degrees on heavy-duty bushings. This eliminates the "scrubbing" effect you experience with single-wheel jacks. Repositioning your trailer becomes a one-person job.

Replaceable wheels attach with heavy-duty bolts. When wear occurs after years of use, you replace just the wheels—not the entire jack assembly.

FAQ

Q: Why go for a product over a wheel?

A: Its double surface area prevents the jack from sinking and makes the trailer easier to pivot by hand.

Q: What maintenance does the twin wheel assembly need?

A: For smooth 360-degree rotation, lubricate zerk fittings with marine-grade grease and check pivot pins for wear.

Q: Can these wheels handle highway speed?

A: Trailer jacks only support static and low-speed manoeuvring. You must retract or swing them during transport.

Q: How can I tell if dual wheels fit my trailer frame?

A: For 3-inch to 5-inch frames, most dual-wheel jacks use a universal bolt-on bracket. Check pull-pin clearance before purchase.

Q: Can worn wheels be replaced?

A: Professional dual wheel jacks have interchangeable wheels attached by heavy-duty fasteners for convenient repair without replacing the jack.
