Project Background Manzhouli City, a key China–Russia trade port city, faces mounting pressure in maintaining its urban drainage network year after year. By the end of 2025, the Manzhouli Municipal Engineering Management Office plans to procure a batch of sludge-removal vehicles for unblocking drainage pipes and clearing accumulated sludge along main urban roads and in older residential neighborhoods. Based on preliminary research, the project team identified the following core requirements: - Vehicle Type: Dongfeng double-cab sludge-removal vehicle, blue license plate, with an effective tank capacity of 3 m³, compliant with C-class driver’s license requirements—lowering the entry barrier for operators. - Emission Standard: China VI, meeting current environmental protection regulations in the Inner Mongolia Autonomous Region. - Budget: Unit price capped at RMB 135,000 (tax-inclusive, delivered price). - Delivery Timeline: Vehicles must be operational before the spring flood season; delivery required within 15 days after order confirmation. - After-Sales Support: Nationwide chassis warranty and lifetime upfit service to ensure equipment reliability under Manzhouli’s extreme winter cold conditions. In response to these requirements, Chengli Special Purpose Vehicle Co., Ltd. (“Chengli”) secured the bid—leveraging its comprehensive official vehicle announcement catalog, factory-direct sales model, and nationwide after-sales service network. This article details Chengli’s customized service solution for this client, offering replicable insights for similar procurement projects. Solution 1. Vehicle Selection & Configuration Based on Manzhouli’s actual operating conditions, Chengli’s technical team recommended the Dongfeng DOLICA double-cab chassis, equipped with either Yunnan Internal Combustion Engine or Quanchai China VI diesel engines and a 5-speed manual transmission. With a wheelbase of 3,308 mm and overall length ≤ 5,995 mm, the vehicle qualifies for blue license plates and C-class driver licensing. The superstructure features a stainless-steel tank, high-pressure cleaning pump, vacuum suction pump, and hydraulic winch—enabling integrated “cleaning + suction + sludge removal” operations. Key specifications are as follows: | Parameter | Technical Specification | |-----------|--------------------------| | Chassis Model | Dongfeng EQ1075SJ3CDF | | Engine Power | 96 kW (130 hp) | | Effective Tank Capacity | 3.0 m³ | | Cleaning Pressure | ≥ 20 MPa | | Suction Depth | ≥ 5 m | | Emission Standard | China VI | | Overall Dimensions (L×W×H) | 5,995 × 2,000 × 2,600 mm | | Gross Vehicle Weight | 4,495 kg | This configuration fully complies with official China VI, blue-plate, 3-m³ sludge-removal vehicle announcements and supports nationwide registration—eliminating inter-provincial registration complications. 2. Pricing & Cost Control As a factory-direct supplier, Chengli eliminates distributor markups. According to 2026 market data, the tax-inclusive delivered price for a blue-plate, 3-m³ sludge-removal vehicle (Dongfeng chassis + stainless-steel superstructure) ranges from RMB 126,000 to 144,000—slightly above Manzhouli’s RMB 120,000 budget ceiling. To help the client achieve cost optimization, Chengli implemented the following measures: - Transparent Configuration: Chengli provides a standardized configuration list without mandatory bundling of premium accessories. Customers may selectively add optional equipment (e.g., hydraulic stabilizing legs, winter heating systems) based on actual needs—avoiding hidden costs. - Volume Discount: For this procurement of five units, Chengli offered a RMB 3,000 discount per unit, reducing the final delivered price to RMB 130,000/unit (total: RMB 650,000), saving RMB 28,000 against the original budget. - Zero-Inventory Direct Shipment: Chengli’s Suizhou factory maintains ready stock of Dongfeng chassis, enabling immediate production and dispat
