3-Axle Side Dump Semi Trailer
Product Overview
The 3 Axle Side Dump Semi Trailer is engineered for heavy-duty bulk material transportation where fast unloading and high productivity are essential.
Unlike conventional rear dump trailers, the side tipping system allows unloading without requiring large rear clearance, making it ideal for confined working environments such as tunnels, mines, construction sites, and industrial plants.
Manufactured with high-strength Q345B steel and a reinforced chassis, the trailer offers excellent load capacity, superior structural durability, and a long service life. The optimized hydraulic lifting mechanism ensures smooth and reliable dumping while reducing operating time and labor costs.
Its robust design, customizable configurations, and low maintenance requirements make it an ideal choice for dealers, fleet owners, and transportation companies worldwide.
Key Features
- Efficient Hydraulic Side Dumping System
The hydraulic side tipping mechanism enables quick, stable, and efficient unloading from one side without requiring rear dumping space.
This significantly reduces unloading time while improving productivity on construction sites, mines, and material handling operations.
- Heavy-Duty Structural Design
Built with high-strength Q345B carbon steel and reinforced cross members, the trailer delivers exceptional durability under continuous heavy-load operations.
The wear-resistant body is suitable for transporting abrasive materials such as stone, gravel, coal, and ore.
- Stable & Anti-Rollover Performance
The optimized center of gravity, reinforced chassis, and precisely engineered dumping angle provide excellent stability during unloading.
This minimizes rollover risks and ensures safer operation on uneven or sloped terrain.
- Large Payload Capacity
Available with 3-axle configurations, the trailer supports payload capacities from 30 to 50 tons, meeting various transportation requirements for mining, quarrying, and construction industries.
- Reliable Hydraulic System
Equipped with high-quality multi-stage hydraulic cylinders and hydraulic components, the lifting system provides powerful, smooth, and reliable tipping performance with low maintenance costs.
- Flexible Customization
Body length, box height, axle brands, suspension types, hydraulic systems, and painting colors can all be customized according to customer requirements and local road regulations.
