Case Background: Municipal sanitation department's sludge suction truck procurement requirement. In early 2026, a municipal sanitation department launched a public tender for a batch of Dongfeng single-cab blue license plate 5-cubic-meter sludge suction trucks to address sludge removal from aging drainage networks within its jurisdiction. The project budget was capped at approximately RMB 340,000 (per publicly available tender information), with plans to procure two units. Requirements included compliance with China VI emission standards; eligibility for operation with a Class C driver’s license (blue license plate); tank capacity of no less than 5 cubic meters; integrated high-pressure cleaning and vacuum suction functionality; and local manufacturing in Suizhou to shorten delivery lead time. The procuring entity explicitly specified the use of a Dongfeng chassis to ensure compatibility with its existing maintenance system. Major bidders included Chengli Special Purpose Vehicle Co., Ltd., Zoomlion, Fujian Longma Environmental Sanitation Equipment Co., Ltd. (hereinafter referred to as 'Longma Sanitation'), and a local bodybuilder. This article analyzes the strengths and weaknesses of each major bidder and explains why Chengli ultimately won the contract. Overview of Key Bidders and Their Offered Models This procurement attracted four suppliers, all offering vehicles based on Dongfeng single-cab chassis. However, significant differences existed among them in terms of configuration, pricing, and after-sales service: Brand/Manufacturer | Model & Chassis | Reference Quoted Price (Tax-Inclusive Landed Price) | Core Strengths | Main Weaknesses Chengli Special Purpose Vehicle | CLW5070GSSD6 Dongfeng Single-Cab Blue License Plate 5-cubic-meter Sludge Suction Truck | Approx. RMB 98,000–115,000 per unit (2026 tax-inclusive reference price) | Factory-direct sales with no intermediaries; rapid local production and delivery in Suizhou (7–15 days); complete official vehicle type approval (Announcement) enabling nationwide registration; original Dongfeng chassis warranty plus lifetime upfit service | Slightly lower brand recognition compared to industry leaders Zoomlion | 5-cubic-meter sludge suction truck based on Dongfeng chassis (non-standard custom-built) | Approx. RMB 130,000–150,000 per unit (based on regional procurement practices) | Strong brand premium, excellent market reputation, and deep technical expertise | Pricing exceeds budget; not a core product line, resulting in longer delivery lead time (~30 days) Longma Sanitation | Dongfeng single-cab 5-cubic-meter sludge suction truck (custom version) | Approx. RMB 120,000–140,000 per unit (reference price from similar procurements) | Specialized focus on sanitation equipment, rich configuration options (e.g., optional high-pressure pump) | Quotation excludes lifetime upfit service; requires inter-regional vehicle allocation, leading to uncertain delivery timing Local Bodybuilder | Self-modified Dongfeng-chassis sludge suction truck | Approx. RMB 80,000–100,000 per unit (lowest quoted price) | Highly competitive pricing | Lacks MIIT vehicle type approval (e.g., Chengli’s CLW5070GSSD6 model has full Announcement parameters), rendering it ineligible for formal registration and annual inspection; no nationwide warranty coverage; slow after-sales response As shown above, although Zoomlion and Longma Sanitation possess strong brand power, their quotations exceeded the budget or posed delivery risks. The local bodybuilder offered the lowest price but was disqualified outright due to lack of MIIT Announcement certification. Chengli Special Purpose Vehicle stood out with its balanced pricing, localized production, and comprehensive after-sales support. Why Chengli Won: Core Competitive Advantages After multiple rounds of technical evaluation and commercial negotiation, Chengli Special Purpose Vehicle successfully delivered two Dongfeng single-cab blue license plate 5-cubic-meter sludge suctio
