As a professional Chinese electric commercial vehicle manufacturer, Dowway specializes in the R&D, engineering, and custom production of intelligent, lightweight new energy chassis for urban utility applications. Dowway 4.5-ton electric special vehicle chassis is meticulously engineered for sanitation, waste collection, and last-mile logistics, combining structural efficiency, smart energy use, and cost-effective ownership.
Key Features & Innovations:
- CAE-Driven Lightweight Frame: Constructed with high-strength 510L steel rails, the chassis undergoes multi-condition simulation (stiffness, strength, torsion, braking, durability) to enable precision local reinforcement—resulting in a 5% lighter frame (15–25 kg saved) without compromising safety.
- Weight-Optimized Suspension: Equipped with parabolic (fewer-leaf) leaf springs, delivering required load capacity while reducing unsprung mass and improving ride comfort.
- Data-Informed Battery Sizing: Powered by a 57.6 kWh lithium iron phosphate (LFP) battery, configured based on real-world sanitation fleet operational data. The side-mounted layout saves underfloor space and avoids over-provisioning—lowering both chassis weight and total purchase cost.
- Integrated Structural Design: Multiple brackets and cross-members are consolidated through CAE analysis, reducing part count and overall mass.
- Ultra-Light Curb Weight: At just 1,800 kg, this chassis is ～3% lighter than industry averages, maximizing payload capacity for compact garbage trucks, street sweepers, or delivery bodies.
With a compact footprint (5115 mm length), 2800 mm wheelbase, and 240 km NEDC range, Model #46 is ideal for dense urban environments. As a direct OEM factory from China, we offer:
- Full customization of powertrain, control logic, and body interfaces
- Rapid prototyping and small-batch production
- Global certification support (e.g., EU, ASEAN, Africa)
- Private labeling or co-development partnerships
Choose Dowway Vehicle for a smarter, lighter, and truly adaptable electric solution—designed in China, built for your city.
