3 Axle U-Shape Rear Dump Trailer
Quick answer: choose this 3 axle U-shape rear dumper trailer when you want cleaner rear discharge flow for sand, gravel, coal, and quarry aggregates, and your routes justify a lighter air-suspension tipper rather than a rough-service mechanical mining trailer. The represented stock type uses a 10600 × 2550 × 3580 mm body, 35CBM effective volume, up to 55 ton payload positioning, BPW-running-gear compatibility, 385/65R22.5 single tyres, front axle lift, Jiaheng hydraulic cylinder, WABCO ABS, and a current USD 14,000 export offer.

3 axle U-shape rear dump trailer: this Kales rear tipper is built for buyers who want a more material-flow-efficient dump body than a standard flat-wall rear tipper, while staying below the cost and duty class of a heavier 60 ton mining U-shape trailer. The represented build combines a 35 cubic meter U-shape body, air suspension, single-wide tyres, front axle lift logic, and a lighter tare structure for quarry and mineral shuttle work.
Engineering guidance from the Kales Vehicle trailer team for fleets comparing standard 35CBM dump bodies, 40 ton mechanical tippers, and heavier mining-spec U-shape rear dump trailers.

Best Fit Operating Profile
This product is strongest for fleets hauling quarry aggregates, washed sand, coal, screened stone, and similar mineral bulk on shorter or medium-distance routes where unloading speed and cleaner discharge matter. It is a better match than a standard box-type tipper when sticky material release and body clean-out efficiency matter, but it is not automatically the best answer for the roughest mine roads or the heaviest mining payload class.
Best for
- Quarry and aggregate fleets that want smoother discharge from a U-shape body
- Sand, coal, gravel, and mineral bulk on more controlled site-to-plant or plant-to-yard routes
- Buyers who value front axle lift, lighter tare, and single-tyre efficiency on return runs
- Operations where air suspension support is serviceable and route quality is not purely off-road abuse
Not ideal for
- Remote mining routes where mechanical suspension and thicker plate are the safer long-term answer
- Jobs that already require a heavier 60 ton mining-spec U-shape tipper from day one
- Buyers who simply need the most standard low-complexity rear dump trailer and do not benefit from the U-shape discharge logic
Why Buyers Choose This U-Shape Rear Dump Trailer
- U-shape unloading logic: the body is built to improve material flow and reduce residue compared with a flatter box-type rear dump body.
- Lighter running package: air suspension, single-wide tyres, and aluminum wheels support fuel and wear efficiency on suitable routes.
- Front axle lift: the empty-return logic helps reduce tyre drag and unnecessary wear.
- Practical middle position: this page sits between the broader 35CBM dump family and the heavier 60 ton mining U-shape tipper.
- Quarry-focused stock logic: the represented configuration is more specific than a generic dump trailer listing and easier to evaluate commercially.
How this page differs from nearby Kales tipper pages
| Product path | Best when | Move away when |
|---|---|---|
| 35CBM rear dump family | You need a broader rear-dump platform with standard and reinforced variants | You specifically want a U-shape quarry body with air suspension and single-wide tyre logic |
| 40 ton mechanical tipper | You want a simpler mainstream rear-dump trailer with easier rough-route maintenance | You want the cleaner discharge and lighter-route logic of this U-shape air-suspension build |
| This 3 axle U-shape rear dumper | You want quarry-focused U-shape discharge, 35CBM volume, and a lighter air-suspension package | You need either a more generic low-cost tipper or a heavier mining-duty trailer |
| 60 ton mining U-shape tipper | You need thicker structure and a heavier mining payload class | Your route and payload do not justify the heavier acquisition and service burden |
Engineering and Serviceability Details
Why the U-shape body matters
On sticky or dense bulk materials, a U-shape dump body can release material more cleanly than a flatter rectangular box. That matters when the fleet is cycling quickly through quarry or mineral routes and cannot afford slow clean-out or half-stuck loads during tipping.
Air suspension, single tyres, and route discipline
The represented stock uses 3 axle air suspension, full vehicle height adjustment, front axle lift, and 385/65R22.5 single tyres. That package can save wear and improve running efficiency, but it also assumes the buyer is not sending the trailer into the roughest abuse conditions without maintenance support. Buyers who already know the route is extremely harsh should compare the mechanical-suspension 40 ton page or the heavier 60 ton mining page before locking the order.
Hydraulics, safety, and support hardware
The stock-type build references a Jiaheng 200-6500 hydraulic cylinder, WABCO ABS, JOST landing legs, pneumatic reverse rear protection, and an electric spare tyre carrier. Those details help distinguish this product from a generic dump listing because they show a more specific operating package rather than only a body size and axle count.
Why this page keeps a fixed Offer instead of AggregateOffer
This page is aligned to one represented export stock type rather than a broad family of unrelated dump configurations. The final order can still be customized, but the commercial signal here is a concrete export unit with a current USD 14,000 reference offer, so a fixed Offer structure remains appropriate.

Questions before ordering
Who should choose this page instead of the 40 ton mechanical dump trailer?+
Buyers who specifically want a U-shape discharge body, air suspension, front axle lift, and single-wide tyre logic should start here. Buyers who need simpler rough-route serviceability should compare the 40 ton mechanical tipper page first.
Is this a better option than the 60 ton U-shape mining trailer?+
It is better only when the job does not need the heavier mining payload class. If the route and material already demand thicker structure and heavier mining-duty support, move to the 60 ton U-shape page.
What cargoes fit this trailer best?+
It is strongest on sand, gravel, coal, screened stone, and similar quarry or mineral bulk that benefits from cleaner rear discharge.
Why are single-wide tyres used on this build?+
They support lower tare and reduced rolling resistance on suitable routes, especially when paired with front axle lift and a lighter-duty return cycle.
What should I confirm before requesting a quote?+
Confirm cargo density, route condition, tipping frequency, maintenance capability for air suspension, tractor saddle height, and whether the operation should stay in this quarry-focused class or move into a heavier mining tipper.
