3 Axle 45m3 Heavy Duty 45 Cubic 80 Ton Dump Semi Trailer

The 3 Axle Dump Trailer, with its extra-large cargo box, powerful hydraulic lifting system, and three-axle heavy-duty chassis, is designed for the large-volume transportation of bulk materials such as ore, sand, coal, earthwork, and construction waste. It is the most efficient bulk material transportation solution for mining, infrastructure, and municipal engineering projects.

Product Details

Cargo Box Structure Design：

U-shaped box: Large volume, thorough unloading, preferred for mines

Square box: Even load distribution, suitable for building materials and earthmoving

Coal-specific box: Raised side panels for maximum volume

Thickened and raised front panel to prevent cargo from surging forward during emergency braking

Arched bottom design allows materials to flow naturally to the unloading port

Hydraulic tailgate switch ensures thorough unloading with a residue rate of <0.5%

Powerful Hydraulic Lifting System:

Rated lifting force of hydraulic cylinders: 50–120 tons

Lifting angle: 45–55° for thorough and clean unloading

Lifting time: < Unloading completed in 60 seconds.

Stable hydraulic system working pressure ensures smooth lifting without any jerking.

Multi-stage hydraulic cylinder design ensures stable lifting and even force distribution.

High-strength frame:

Main beams are made of high-strength steel (Q345/Q550) with high yield strength.

I-beam cross-section main beams offer excellent bending and torsional resistance.

Reinforced sub-beam design ensures even force distribution on the frame during lifting.

Specially reinforced lifting hinge points prevent fatigue cracking during repeated lifting.

The entire vehicle is welded using automated robotic welding, resulting in uniform and defect-free welds.

Multi-Scenario Applications

Mining Scenarios: Large-volume transportation of ore, iron ore, copper ore, and gold ore. HARDOX wear-resistant chassis, undamaged by ore impact. Three-axle heavy-duty 

chassis, stable operation when fully loaded with ore. Large lifting angle, thorough unloading with no residue. Highest mining transportation efficiency in the industry.

Construction and Infrastructure Scenarios: Sand, gravel, earthwork, construction waste, and concrete slag. Extra-large capacity, hauling more in one trip to reduce construction delays. Hydraulic rapid unloading, no waiting at construction sites. Adaptable to complex construction site conditions, strong three-axle passability. Core transportation equipment for infrastructure construction.

Coal Transportation Scenarios: Long-distance trunk transportation of raw coal, refined coal, and washed coal. Heightened side plate version, maximized capacity, suitable for lightweight coal. Large-capacity coal transport: Sealed tailgate prevents coal dust from scattering and polluting the environment. Stable and reliable long-distance transport, the preferred choice for the coal supply chain. GPS monitoring ensures full compliance and traceability of coal transportation.

Urban construction waste transport: Construction waste, engineering spoil, municipal waste. Sealed tarpaulin covering ensures compliant and leak-free transportation. GPS monitoring ensures compliant management of construction waste transport routes. Meets National VI emission standards, allowing unrestricted travel in urban restricted areas. Integration with construction waste management platforms ensures compliant electronic manifest operations.

Agricultural materials transport: Grains, fertilizers, pesticides, and other bulk agricultural materials. Large capacity and high efficiency for rapid transfer during busy farming seasons. Hydraulic unloading reduces manual unloading work. Highly adaptable to rural roads, with good three-axle passability.
