4 Axle 80 Ton Heavy Duty Rear Dump Semi Trailer for Mining Transport

Product Overview

The 4 Axle 80 Ton Heavy Duty Rear Dump Semi Trailer for Mining Transport is a heavy-duty transportation solution engineered for moving and unloading large quantities of bulk materials in mining, quarrying, construction, and infrastructure development.

Unlike standard flatbed or cargo trailers, this rear dump trailer is built with a specialized hydraulic tipping structure, allowing bulk materials to be unloaded quickly and safely through the rear opening. As a core offering in our Tipper Semi Trailer lineup, this design significantly improves transportation efficiency for operations requiring frequent loading and unloading cycles.

With an 80-ton payload capacity and a 4-axle configuration, this dump semi-trailer provides exceptional load support and optimized axle weight distribution. The reinforced chassis structure, heavy-duty dump body, and high-performance hydraulic system make it ideal for transporting heavy, abrasive materials such as ore, stone, sand, gravel, coal, soil, and construction waste.

RoadKing provides customized dump semi-trailer solutions tailored to different destination country regulations, road conditions, cargo types, and specific operational requirements.

Heavy Duty 80 Ton Dumping Capability

Designed for Heavy Bulk Material Transportation

The primary application of this trailer is the efficient haulage of dense bulk cargo. The RoadKing 80 Ton Rear Dump Semi Trailer is widely utilized in:

• Mining Operations: Ore, coal, and mineral transport.

• Quarry Operations: Crushed stone, riprap, and aggregate hauling.

• Construction & Infrastructure: Earthmoving, road building, and bridge construction projects.

Common Transported Materials

• Mining Materials: Iron ore, coal, bauxite, mineral concentrates, quarry stone.

• Construction Materials: Sand, gravel, crushed rock, soil, and recycled construction waste.

Because these materials are dense and abrasive, the trailer utilizes high-tensile steel construction combined with a robust tipping system to withstand repetitive high-impact loading. The large-capacity dump box allows operators to transport more payload per trip, lowering overall operational costs per ton.

Reinforced Chassis & Frame Structure

High-Strength Steel Construction

The chassis is the foundation of any heavy-duty semi-trailer. The RoadKing 80-ton rear dump trailer utilizes a reinforced frame fabricated from high-strength Q345 and T700 steel.

Key Chassis Advantages:

• Superior Load-Bearing Capacity: Built to handle continuous heavy payloads without structural deformation.

• Flexibility & Bending Resistance: Optimized high-tensile main beams resist structural fatigue under uneven loads.

• High Torsional Strength: Maintains frame integrity during off-road operation and steep-angle tipping.

• Extended Service Life: Heavy-duty crossmembers and reinforcement plates strengthen high-stress points.

This heavy-duty design ensures frame stability when operating in harsh conditions, including unpaved haul roads, frequent acceleration/braking, and continuous tipping cycles.

4-Axle Configuration for Superior Stability

Balanced Weight Distribution Under Maximum Payload

The 4-axle configuration is designed for transporters requiring high loading capacity while complying with axle weight regulations.

Key Benefits:

• Even Weight Distribution: Spreads heavy payloads across multiple axles, reducing ground pressure.

• Enhanced Driving Stability: Improves vehicle control on off-road haul routes and uneven terrain.

• Reduced Component Wear: Decreases stress on individual tires, brakes, and suspension components.

Axle & Component Options:

• Axle Brands: FUWA, BPW, or customer-specified brands.

• Customization: Axle capacities, spacing, and lifting axle options can be adjusted according to local road regulations and transport distances.

Heavy-Duty Dump Body (Cargo Box) Design

Built for High-Impact Loading and Rapid Unloading

The dump body is explicitly engineered to resist impact damage from heavy dropped loads (such as large rocks and ore).

Customizable Cargo Box Features:

• Dimensional Customization: Adjustable box length, sidewall height, and total volumetric capacity.

• Plate Thickness Options: Tailored floor and side plate thicknesses using wear-resistant steel.

• Reinforced Ribs: Stiffened side structures prevent box bulging under dense material loads.

The optimized rear door mechanism opens automatically or pneumatically during tipping, facilitating rapid discharge without material blockages.

Hydraulic Rear Tipping System

Fast, Efficient, and Safe Discharging

The semi-trailer is equipped with a high-pressure hydraulic tipping system to raise the dump box smoothly and safely during operation.

Hydraulic System Components:

• Hydraulic Cylinder: Front-mounted heavy-duty telescopic cylinder (e.g., premium HYVA hydraulic cylinders).

• Oil Tank & Valve Assembly: Integrated hydraulic reservoir, control valves, and durable high-pressure piping.

Performance Benefits:

• Reduced Cycle Times: Rapid lifting and lowering speeds minimize downtime at the dump site.

• Operator Safety: Smooth hydraulic response prevents sudden load shifts during discharge.

• Reduced Labor: Fully automated tipping eliminates manual unloading labor.

Suspension System Options

RoadKing offers versatile suspension configurations within our Tipper Semi Trailer series to suit diverse road conditions.

1. Heavy-Duty Mechanical Suspension

• Features: Simple multi-leaf spring structure with equalizer beams.

• Advantages: High durability, low maintenance costs, and exceptional performance on unpaved or rough terrain.

2. Air Suspension System (Optional)

• Features: Pneumatic air bags with automatic height adjustment.

• Advantages: Superior shock absorption, smoother ride quality, reduced payload impact, and extended tire life.

Reliable Running Gear & Components

• Tires & Rims: Standard equipped with 12R22.5 heavy-duty tires (16 pieces + optional spare). Steel or lightweight aluminum rims available.

• Landing Gear: Heavy-duty 28-ton two-speed manual landing gear for stable support during uncoupling.

• King Pin: Heavy-duty interchangeable king pin available in 2-inch (#50) or 3.5-inch (#90) options to fit various tractor fifth wheels.

• Braking System: Dual-line air brake system with optional ABS/EBS configurations to ensure safety in all weather conditions.
