4-axle Rear-tipping Dump Semi-trailer

Standard Vehicle Configuration

Basic Specifications
A 4-axle U-shaped rear-dump semi-trailer with overall dimensions of 12,500 × 2,550 × 3,800 mm; the vehicle length can be customized between 10 and 14 meters to meet specific requirements.
Load Capacity and Curb Weight
Rated load capacity of 80–100 tons and a curb weight of 13.5–15 tons; the design optimizes the balance between load-bearing capacity and vehicle weight.
Cargo Box Design
Cargo box volume ranges from 45 to 60 cubic meters; the side panel height is adjustable, allowing the volume to be modified for flexibility based on different materials and loading requirements.
Applications
Suitable for transporting bulk materials such as sand and gravel, ore, coal, earthwork, and construction waste.
Discharge Performance
The hydraulic system offers a maximum lifting angle of 45°; combined with the U-shaped box structure, this ensures smooth unloading with minimal material residue, thereby reducing the need for manual cleanup.
