4 Axle Wear-Resistant Steel Tipper Semi Trailer

The 4 Axle Wear-Resistant Steel Tipper Semi Trailer is HUAYU's abrasion-spec rear tipper for sand, gravel, and demolition haul: a Baosteel ROCKY 450 body with an 8mm floor and 6mm sidewalls, four 13T FUWA axles on leaf springs, and a HYVA front telescopic hoist. The body carries its own proof: the BAOSTEEL HARD WEAR STEEL BODY and ROCKY 450 plates are mounted on the side wall. Standard volume is 40 cbm, with 45 cbm and other dimensions built to order.

• Baosteel ROCKY 450 wear body: 8mm floor and 6mm sidewalls in the HB 450 hardness class
• HYVA 5-stage front hoist: the red telescopic cylinder mounted ahead of the body front wall
• 4 x 13T FUWA axles: leaf-spring suspension as standard, 16T rating or BPW as options
• 40 / 45 cbm U-shape body: rounded floor-to-wall transition, less residue after each tip
• 60T rated payload: four-axle spread built for quarry and aggregate cycles
• Full-length steel mudguards: rounded fenders cover the whole 4-axle group

NM450-Class Wear Plate Body: 8mm Floor, 6mm Sidewalls

The floor and sidewalls are cut from Baosteel ROCKY 450, a Chinese NM450-class wear plate in the same 450 HBW hardness band as Hardox 450. That hardness is what abrasive loads need: sand, crushed stone, and broken concrete scrape a mild-steel floor thin, while wear plate holds its thickness through years of the same cycles.

The pressed horizontal ribs and the rounded floor-to-wall transition are visible in the side photo, together with the BAOSTEEL wear-steel plate on the panel. Plate thickness is 8mm on the floor and 6mm on the sidewalls.

Leaf-Spring Running Gear: Four 13T FUWA Axles

Under the body sit four 13T FUWA axles on multi-leaf mechanical suspension, the configuration most operators ask for where site roads break air bags and where any village workshop can re-arch a spring. The close-up photo shows the 10-stud steel wheels and the yellow torque-check markers on the hub nuts. Air suspension remains an option for fleets that run long paved corridors, and its upkeep is covered in our air suspension airbag guide.

The U-shape discharge behavior and the 50-degree tipping geometry are engineered identically across this body program. For the full explanation of body angle, lift time, and why the U profile empties cleaner, see the 4 Axle U Shape Rock Body End Dump Semi Trailer page, which covers the air-suspension sister configuration. When a side-discharge layout suits the route better, the side tipper vs end tipper comparison walks through that choice.

• King pin: 2 inch (50mm) or 3.5 inch (90mm) JOST, bolted
• Landing gear: 28T JOST double-speed, cross-braced pair
• Brakes: dual-line air brake with WABCO ABS
• Tires: 12R22.5 radials with 385/65R22.5 super-singles optional; the photographed unit runs Aeolus and Advance
• Electrical: 24V LED side markers and tail lamps, 7-pin socket
• Spare wheel: one, carried on the front bulkhead
• Paint: 2-part epoxy primer plus polyurethane topcoat; white as photographed, other colors to order

Where this tipping trailer earns its keep:

• Quarry and pit operators hauling blasted rock and overburden on short pit-to-crusher cycles
• Aggregate and sand haulers feeding batching plants and road projects, where the wear floor shrugs off daily abrasion
• Demolition and recycling contractors loading broken concrete and rubble that would dent a mild-steel box
• Fleets on rough corridors in Africa, the Middle East, and Central Asia, where leaf springs stay field-serviceable far from dealer networks

A four-axle end dump fleet of the same body program already works in Zimbabwe. See the delivery case for how that order was configured.

Frequently Asked Questions

What body volume and payload does this 4 axle tipper trailer carry?

The standard body holds 40 cbm, with 45 cbm and other dimensions built to order, and rated payload is 60T on the four 13T FUWA axles. As an end dump semi trailer its capacity sits in the middle of the 24 to 80 cbm range this chassis family covers, and the U-shape body carries the load lower than a square box of the same volume. Tell us your material density and local axle-load rules and we confirm the exact volume before production.

How is the price quoted for this tipper semi trailer?

The final price depends on your chosen specs and options: air suspension instead of leaf springs, BPW or 16T axles, a 45 cbm body, and custom paint all move the figure. Send an inquiry for a detailed FOB Qingdao quotation, or ask for a CIF quote to your destination port — sea freight and marine insurance are then included. We reply within 24 hours.

Is the ROCKY 450 body the same steel as a Hardox tipper trailer body?

Same hardness class, different mill. ROCKY 450 is Baosteel's NM450-class wear plate, rated in the 450 HBW band like Hardox 450 from SSAB, and it does the same job: a hard, abrasion-resistant floor and walls for sand, gravel, and rubble. HUAYU builds with ROCKY 450 because it is stocked domestically in 8mm and 6mm plate, which keeps lead time short without giving up wear life.

What is the advantage of a U-shape tipper trailer body over a square box?

The U-shape body has no internal corners, so the load starts moving as one mass and leaves less residue stuck in the box after each tip. Its rounded floor-to-wall transition also removes the corner welds that crack first on square boxes, and the curved shell is stiffer for its weight, which keeps tare down. For sticky or abrasive material those three gains matter more than the slightly lower nominal volume.

What cylinder lifts this hydraulic tipper trailer?

A HYVA front-mount telescopic cylinder with five stages, the red unit visible ahead of the body front wall in the photos. Front mounting keeps the lift force in line with the body's center of gravity, and HYVA's global dealer network stocks seals and parts in most markets this trailer ships to. The hoist pairs with a PTO-driven pump on the tractor side.

What warranty covers this trailer?

10-year warranty on the main beam, with a 1-year warranty on the body structure and welded joints. Component warranties follow the original manufacturer's terms (HYVA, FUWA, JOST, WABCO, Baosteel).

How long does production and delivery take?

A standard single trailer ships in 7-15 working days after deposit, including final inspection, export documentation, and loading. Custom configurations or orders of 2-10 units take 15-25 working days, and fleets of 20 or more take 25-45 working days. Sea transit is quoted separately by route, typically 20-40 days.

What payment terms does HUAYU accept?

30% deposit by T/T confirms your order; the 70% balance is paid before shipment. When your trailer is finished we send photos and videos of the actual unit, so you see what you bought before paying the balance. For larger orders we accept an irrevocable L/C at sight.

Ask for a full quote with the destination port, preferred suspension type (air or leaf) and body volume (40 / 45 cbm), and any custom specifications. The HUAYU sales team replies within one working day on weekdays. Reach us on the contact page or WhatsApp from any page on the site.
