As an innovative Chinese electric commercial vehicle manufacturer, Dowway Vehicle delivers intelligent, scalable, and highly efficient new energy platforms for urban and regional utility missions. Our 18-ton electric special vehicle chassis is engineered specifically for medium-duty sanitation vehicles, garbage compactors, street sweepers, and multi-purpose utility bodies, blending advanced lightweighting, smart energy management, and flexible configuration.
Core Engineering Highlights:
- CAE-Optimized Lightweight Frame: Built with high-strength 510L steel rails, the chassis undergoes rigorous simulation across stiffness, strength, torsion, braking, and durability scenarios. This enables precision local reinforcement and achieves a 5% weight reduction versus conventional designs—without sacrificing structural integrity.
- High-Performance Lightweight Suspension: Features fewer-leaf (parabolic) leaf springs made from 50CrVA high-tensile spring steel, offering excellent fatigue resistance and load capacity while significantly reducing unsprung mass.
- Data-Driven Battery Sizing: Offers four battery capacity options (162.05 / 194.46 / 231.07 / 271.06 kWh) using lithium iron phosphate (LFP) cells from CALB (China Aviation Lithium Battery). Configurations are based on real-world sanitation fleet operational data, ensuring optimal range (240–280 km) while avoiding over-engineering—lowering both chassis weight and total cost of ownership.
- Deep System Integration:
- Integrated thermal management unifies battery cooling and cabin air conditioning.
- Multi-in-one high-voltage controller consolidates power distribution.
- Structural brackets and mounts use integrated casting or stamping to reduce part count and mass.
- Flexible Wheelbase & Payload: Available in 4500 mm or 4800 mm wheelbase variants, with curb weights of 5,700 kg or 5,900 kg, enabling ideal weight distribution for various body types—including rear-loading compactors and side-arm collectors.
Powered by a robust 120/200 kW permanent magnet synchronous motor (500/1000 Nm torque), this chassis delivers smooth, quiet, and responsive performance in stop-and-go urban environments.
As a direct OEM factory from China, 1V Truck provides:
- Full customization of battery size, control logic, and PTO interfaces
- Co-engineering with bodybuilders for seamless integration
- Support for international certifications (EU, GCC, ASEAN, etc.)
- Scalable production with private labeling or joint branding
Choose Model #49 from Dowway Vehicle—a smart, lightweight, and truly adaptable electric platform built through Chinese engineering excellence and customer-centric innovation.
