Release Date: May 15, 2026 Released By: Chengli Automobile Group Co., Ltd. · New Energy Special-Purpose Vehicle Division In response to China’s national “Dual Carbon” strategy and the growing demand for new-energy transformation in urban and rural sanitation, Chengli Automobile Group has partnered with Dongfeng Commercial Vehicle to officially launch its new series of pure-electric special-purpose chassis, available in gross vehicle weight (GVW) ratings of 18–32 tons. Developed through forward engineering based on Dongfeng Commercial Vehicle’s proven heavy-duty truck platform, this chassis series integrates top-tier “three-electric” (battery, motor, and electronic control) components from industry-leading suppliers—including CATL, Ruipu Lanjun, Jingjin Electric, Suzhou Lükuo, and Fast Gear—ensuring comprehensive suitability for diverse operational scenarios such as municipal sanitation, road sweeping, waste collection and transportation, sewage treatment, greening irrigation, and emergency support. This document constitutes the official technical specification released by Chengli Automobile Group’s corporate website. All parameters, configurations, and warranty policies herein reflect the original factory announcements. Sales are conducted exclusively via direct headquarters distribution—eliminating dealer markups and intermediary involvement—to guarantee procurement safety, regulatory compliance, and reliable after-sales service. I. Product Positioning & Platform Overview The newly launched pure-electric chassis series covers four GVW classes: 18, 25, 31, and 32 tons. Featuring dual thermal management systems (air-cooled and liquid-cooled), AMT automatic transmission, fully floating cab design, and high-strength frame construction, the platform delivers four core advantages: enhanced safety, extended range, superior reliability, and broad adaptability. Specifically engineered for heavy-duty, continuous-operation sanitation applications, the chassis achieves IP67/IP68 ingress protection for battery packs and meets all-weather outdoor operational standards for motors and controllers. It seamlessly supports mainstream sanitation upfit models—including street sweepers, compression garbage trucks, hook-lift trucks, water sprinklers, dust suppression vehicles, high-pressure cleaning trucks, and road contamination removal vehicles—making it one of the most versatile and dependable dedicated chassis platforms currently available in China’s new-energy sanitation sector. II. Key Technical Highlights • Premium Three-Electric Components: Phosphate iron lithium batteries from CATL and Ruipu Lanjun; high-power permanent-magnet synchronous drive systems from Jingjin Electric, Suzhou Lükuo, and Fast Gear—renowned for exceptional performance stability and industry-wide recognition. • Advanced Protection Rating: Batteries, motors, and controllers all meet IP67/IP68 protection standards—ensuring safe, reliable operation under rain, shallow-water conditions, and prolonged outdoor exposure. • Rapid Charging Capability: DC fast charging supported across the entire series; 20%–90% state-of-charge (SOC) in ≤60 minutes; 20%–100% SOC in ≤90 minutes—minimizing disruption to scheduled sanitation operations. • Extended Warranty Coverage: Uniform 8-year battery warranty; motors and controllers covered for up to 5 years or 500,000 km—the longest in the industry. • High-Load-Bearing Frame: Dual-layer high-strength main beams (250–300 mm in height), delivering exceptional load capacity, structural rigidity, and compatibility with a wide variety of sanitation body installations. • Fully Floating Cab: D560 and D320 cab series, with optional mechanical or air-suspension damping—enhancing driver comfort during long-haul and continuous-duty operations. • Factory-Backed Service Network: Nationwide coverage via Dongfeng’s 820-service-center network; 24/7 customer support via 400 hotline; dedicated one-on-one after-sales coordination di
