3 Axle 45 CBM Mining Tipper Semi Trailer

The 3 Axle 45 CBM Mining Tipper Semi Trailer is HUAYU's rear-tipping dump trailer for mine-site duty: a 45 cbm rectangular body, a 100 ton site rating, and 12.00R20 deep-block mining tires on 10-stud steel wheels. The yellow unit photographed here carries both markings: a round 100 t roundel over the axle group and a ROCKY450 wear-plate badge on the body side. A HYVA front-mount telescopic ram lifts the body to roughly 50 degrees.

• 100 ton site rating: mining-class payload for pit-to-crusher cycles
• ROCKY 450 wear body: 8mm Baosteel floor, 6mm sides, for abrasive loads
• ~50° tipping angle: clears damp sand and sticky overburden in one lift
• HYVA front-mount ram: multi-stage telescopic, leaves the underfloor clear
• 12.00R20 mining tires: deep-block tread, 12 fitted plus 2 spares
• 3 x 13T FUWA axles: 10-leaf mechanical stack, 16T or BPW optional
• JOST 28T landing gear: two-speed, with sand shoes for soft bench ground

ROCKY 450 Wear Body: 8mm Floor, 6mm Sides

The body side wears a ROCKY450 plate, and it states the build material: floor and side walls are pressed from Baosteel ROCKY 450 wear-resistant steel, 8mm on the floor and 6mm on the sides. On abrasive loads like blasted granite, iron ore, or river gravel with sharp fines, wear plate holds its thickness where mild-steel bodies scour thin along the load lines.

Three pressed horizontal ribs keep the walls flat under heaped loads, and the green top rail is a reinforced section, not a trim strip. The rear photos show the mine-site hardware that comes with the spec: caged LED tail clusters, full-length conspicuity tape, and the factory 40/25 km/h site-speed decal on the tailgate.

Mine-Site Running Gear: 12.00R20 Block Tires and a 10-Leaf Stack

The tires are 12.00R20 with a deep-block mining tread on 8.5-20 ten-stud steel disc wheels: twelve fitted, two spares, one carrier under the chassis mid-frame. Deep-block tread bites on loose bench surfaces and sheds stones that would drill into a highway rib pattern.

Behind the wheels sit three FUWA 13-ton axles (16-ton optional, BPW on request), T30/30 spring brake chambers, and a dual-line air system with WABCO ABS. The suspension is a mechanical multi-leaf stack, 90mm wide and 16mm thick at 10 layers per side, sized for the 100 ton site rating badged over the axle group.

For the full wear-plate comparison (ROCKY 450 hardness numbers, how it stacks up against Hardox 450, and when a U-shape body beats a rectangular one), see the 3 axle U-shape rock body page. The reasoning behind putting a 100 ton unit on leaf springs instead of air suspension is laid out on the 100 ton heavy duty rear dump page.

JOST Gear, WABCO Brakes, Q345B Beam: The Rest of the Spec Stack

• Kingpin: 2 inch (50#) JOST as standard, 3.5 inch (90#) optional, on a bolted plate
• Landing gear: JOST 28T two-speed with sand shoes for soft ground
• Brakes: dual-line air, WABCO ABS, T30/30 spring chambers
• Electrical: 24V system, LED tail clusters in mesh cages, caged side markers, 7-pin socket
• Main beam: Q345B high-tensile steel, 500mm heavy I-section
• Paint: 2-part epoxy primer plus polyurethane topcoat, yellow with green top rail as shown
• Accessories: lockable side tool box, under-slung spare wheel carrier, front-wall access ladder

Who Buys a Mining-Spec 3 Axle Tipper Trailer

• Open-pit mine and quarry operators moving ore, blasted rock, or overburden between bench and crusher, where the 40/25 km/h site-speed rating applies and abrasion kills mild-steel bodies
• Aggregate and river-sand contractors in East and West Africa running pit-to-plant cycles of 40-45 cbm per trip on mixed laterite and paved roads
• Infrastructure subcontractors in the Gulf and Central Asia hauling rock fill and gravel for highway, dam, and port projects with unpaved site access
• Fleet owners replacing highway-spec tippers that wore out early on dense, sharp-edged loads — the duty this mining dump trailer is built for

Frequently Asked Questions

Is 45 cbm the right end dump trailer capacity for dense ore?

Run the density math. Loose iron ore sits around 2.4-2.6 tons per cubic meter, so even 25 cbm of ore already exceeds the 100 ton site rating. With dense ore you simply load below the coaming rail. The 45 cbm body is sized for limestone, aggregate, sand, and coal in the 1.4-1.8 t/m³ band, where a heaped load lands at 63-81 tons. If your main cargo is dense ore, tell us the material density and we will spec a reduced-volume body.

What tipping angle does the body reach, and how fast is the dump cycle?

Approximately 50 degrees, which is past the repose angle of damp sand and sticky overburden, so loads clear in one lift without shaking the body. Cycle time depends on your tractor's PTO and hydraulic flow rather than on the trailer; with a healthy truck-side supply, a full raise-hold-lower cycle stays under a minute. The multi-stage HYVA front cylinder keeps the lift stable through the whole arc.

Should I choose an end dump semi trailer or a side tipper?

Choose the end dump layout (this trailer) when your dump points are reasonably flat and firm and you want the fastest, simplest unloading cycle with the fewest moving parts. Choose a side tipper when you regularly tip on uneven ground or need to lay a windrow along the dump edge, because side tipping keeps the body's center of gravity low during discharge. We compared both layouts in detail in side tipper vs end tipper, including the stability math that decides it.

How is this mining tipper different from the 100 ton heavy duty rear dump?

They are the same 3-axle heavy platform: same 100 ton site rating, same running gear, same body dimensions band. This page documents the mining-spec unit: yellow and green mine livery, ROCKY 450 wear-plate body, 12.00R20 mining tires, and the site-safety kit. The 100 ton heavy duty rear dump semi trailer page goes deeper into what the 100 ton rating means for road-legal payload. If your work is mostly on public roads, start there. If it is mostly on site, this is the page to quote from.

What is the price of this mining tipper semi trailer?

The final price depends on your chosen specs and options: 16T axles or BPW running gear, a 40 or 50 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.

What warranty comes with this mining tipper?

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, WABCO, JOST, Triangle, CHENGSHAN, Baosteel).

What are the payment terms?

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.
