Autonomous Container Transporter – 4-Axle 70-Ton
Overview
This case analysis introduces the 8×4 symmetrical wire-controlled chassis flatbed vehicle, designed to meet the demands for heavy-load, high-adaptability transport equipment in modern logistics.
With 450mm maximum ground clearance and 70-ton rated load capacity, it effectively solves the industry challenge of heavy container transportation on unpaved roads, providing revolutionary solutions for ports, mines, and large construction sites.
Basic Parameters
| Parameter | Specification |
|---|---|
| Rated Load | ≥70 tons |
| Curb Weight | ≤20 tons (including battery) |
| Power Configuration | Dual permanent magnet synchronous motors (single ≥135kW) |
| Battery Capacity | ≥282kWh |
| Range | ≥100km (SOC 95%-20%) |
| Max Speed | ≥30km/h loaded, ≥35km/h unloaded |
| Min Turning Radius | ≤8.5m |
| Max Gradeability | ≥10% (fully loaded continuous) |
How It Works
The vehicle features all-wheel steering with electro-hydraulic control system, achieving precise manipulation through wire-controlled technology.
The dual permanent magnet synchronous motor drive system delivers powerful performance, combined with European heavy-duty suspension and mining-grade axles to ensure stable operation under 70-ton loads.
An intelligent management system monitors tire pressure, battery status, and vehicle parameters in real-time, supporting multiple modes including bidirectional travel and figure-eight steering.
The Challenges
- Mobility Challenges: Traditional equipment cannot handle complex unpaved roads
- Load Limitations: Conventional flatbeds struggle with 70-ton container transport
- Control Precision: Heavy loads require more accurate steering and braking control
- Environmental Requirements: Large transport equipment must meet strict emission standards
