Usually ships in 20 days or so if we're running at capasity—it's pretty much a standdard item for us, so lead times are usually reliable but check on the MOQ. We've got these double reduction gear legs with a sliding gear shift that most semi-trailer buyers go with for the 28-ton max payload, finished in powder coat that you can customize color on.
Basically it's for heavy-duty trailer applicaion where you don't want the leg to give out after a few dozen lifts. The rolled high-grade steel lead screw and alloy steel transmission gears are better than reagent grade for this sort of stress, but it's not suited for lighter trailers where a single-speed unit would do the job cheaper.
(We usually have stock for 500 units or so, but confirm lead time on larger orders) The floating nut design is a real detail that buyers don't always ask about—it makes lifting easier than fixed nut designs, and we've passed the ABS drop tests on these. One thing no one mentions until they get it is that the sliding gear shift can feel a bit stiff when it's brand new, but it loosens up.
And you'll get a COA with each batch, usually showing HPLC purity and static load test results—we run those on every production run, not just random samples. The powder coating isn't just cosmetic; it's a tougher finish than paint for corrosion resistnce, so it'll hold up better than most in wet conditions.
Most buyers negotiating bulk pricing ask about the TTMA and AAR compliance first, then want to know if reverse mount is included—it is, and we don't charge extra for it. The 28-ton rating is at the structrual limit, so most operations run it around 24-25 tons for safety margin, but the certification gives you the headroom.
It basically gives you more lifting power with less effort. The double reduction gears multiply the torque so you can easily handle that 28-ton max payload without wrestling the crank.
Yes, they're ABS certified along with TTMA and AAR compliance. That certification means they've passed rigorous safety and performance tests required for marine and heavy transport equipment, so you're getting a reliable, code-approved component.
Absolutely, we offer customizable colors to match your trailers. Since our production capacity is large scale, custom colors aren't a problem—just let us know the RAL code, and we'll work out the pricing based on your order volume.
With our large-scale production setup, lead times are generally 15-25 days for bulk orders, but it depends on the quantity and color customization. Since the MOQ is negotiable, just reach out with your numbers and we'll nail down a schedule.
The floating nut design reduces wear on the lead screw by allowing it to self-align under load. That means less binding, smoother operation, and a longer service life—especially when you're cranking up and down under heavy trailers.
