3 Axle U-Shape Tipper Trailer

3 Axle U-Shape Tipper Trailer

Manufactured in our own semi-trailer workshop, the 3 Axle U-Shape Tipper Trailer combines a 45 m³ curved U-body with a heavy-duty three-axle chassis and a HYVA hydraulic lifting system. Its streamlined U-shaped walls let material flow out quickly and completely — with almost no sticking or residue — making it the ideal choice for hauling sticky and wet bulk cargo such as wet coal, clay, ore fines and construction spoil.

U-Shape Body Design for Clean Discharge

The U-shaped (curved) body is the defining feature of this trailer. Unlike a square box, the streamlined walls and arched bottom let material flow naturally toward the discharge edge, so sticky or wet cargo — wet coal, clay, ore fines and spoil — empties quickly with almost no sticking. The thickened, raised front panel prevents load surging during emergency braking, and residue after tipping is typically below 0.5%. The curved walls also add structural rigidity against side pressure, helping the body resist deformation under repeated heavy loads.

Powerful Hydraulic Lifting System

A front-end telescopic cylinder delivers a rated lifting force of 50-120 tons and a 45-55° lifting angle, completing a full discharge in under 60 seconds. Stable working pressure ensures smooth lifting without jerking, while the multi-stage cylinder design distributes force evenly for safe, repeatable tipper operation.

High-Strength Frame & Reinforced Hinges

Main beams use Q345/Q550 high-strength steel with an I-beam cross-section for excellent bending and torsional resistance. The reinforced sub-beam and specially strengthened lifting hinge points prevent fatigue cracking during repeated tipping. The frame is welded with automated robotic welding for uniform, defect-free joints.

Mining & Ore Haulage

Large-volume transport of ore, iron ore, copper ore and overburden. The U-body sheds damp concentrates and fines cleanly, the three-axle heavy-duty chassis stays stable when fully loaded, and the large lifting angle ensures residue-free unloading.

Construction & Infrastructure

Hauls sand, gravel, earthwork, construction spoil and slag. Extra-large capacity reduces trips, rapid hydraulic unloading eliminates site waiting, and the U-body prevents wet spoil from sticking inside the box.

Agricultural Materials Transport

Large capacity and high efficiency for rapid transfer of grain, fertilizer and other farm materials during busy seasons. Hydraulic unloading reduces manual labour, and good three-axle passability suits rural roads.

23 Years of Semi-Trailer Manufacturing Excellence

Founded in 2003, Chengda Group has 23 years of semi-trailer manufacturing experience and exports to over 80 countries and regions. Holding CCC, BV, ISO and WMI certifications, we manufacture flatbed, low-bed, skeleton, tanker and tipper semi-trailers in our own workshop — so every U-Shape Tipper Trailer is built, inspected and documented before it leaves our facility.

Q1: Why choose a U-shape body instead of a square box?

The curved U-shape lets material slide out along the walls and arched bottom, so sticky or wet cargo — wet coal, clay, ore fines — discharges almost completely with very little residue. Curved walls are also stiffer against side pressure, so the body resists deformation under repeated heavy loads.

Q2: Can the volume, payload and configuration be customized?

Yes. We build every trailer in our own workshop, so box volume (from around 30 m³ upward), side height, steel thickness, axle capacity (13T/16T), suspension type and paint colour can all be tailored to your cargo density and road conditions.

Q3: What information should be confirmed before ordering?

1) Cargo type and density; 2) required volume and payload; 3) axle and tyre configuration; 4) any local registration requirements; 5) trade term and delivery schedule. Confirming these upfront avoids delays and extra costs.

Q4: What is the delivery lead time and payment terms?

Standard models: 20-30 working days after deposit and drawing confirmation; heavily customized orders: 30-40 working days. Payment is 30% T/T deposit with 70% balance against copy of Bill of Lading; FOB / CFR / CIF are all acceptable.

Q5: How is the tipper shipped, and are spare parts available?

We ship by bulk carrier, Ro-Ro or flat-rack container depending on your route and budget, with anti-corrosion protection applied before loading and complete export documents provided for smooth customs clearance. Genuine wear parts — cylinders, seals, brake components and suspension parts — are available and coordinated after delivery.
