I. Project Background: Procurement of Blue License Plate, 5 m³ Sludge Suction Trucks by a Municipal Sanitation Department in Cangzhou. Recently, a municipal sanitation department in Cangzhou procured a batch of blue license plate, 5 m³ Dongfeng single-cab sludge suction trucks to meet the demand for cleaning urban drainage pipelines. According to publicly released tender information, the project budget was capped at approximately RMB 390,000. Chengli Special Purpose Vehicle Co., Ltd. was ultimately selected with its proposed solution, delivering three units of the blue license plate, 5 m³ sludge suction trucks. Customers reported that this model operates flexibly in narrow streets and residential alleys, and can be driven with a Class C driver’s license (blue license plate), thereby reducing labor costs. The core requirements for this procurement included: - Adaptability to narrow road conditions typical of older urban streets in Cangzhou, requiring a compact body and small turning radius; - A single-operation loading capacity of 5 m³ to satisfy routine sludge removal needs; - A Dongfeng single-cab chassis offering convenient maintenance and high parts interchangeability; - Total Cost of Ownership (TCO) recovery within a 5-year timeframe. Ultimately, Chengli’s Dongfeng single-cab, blue license plate, 5 m³ sludge suction truck (reference announcement model series: CLW5070GSSD6) won the bid due to its high cost-performance ratio and robust after-sales service commitment. These vehicles are now operational across Cangzhou’s urban area, and their work efficiency has been well received by customers. II. Total Cost of Ownership (TCO) Analysis by Service Life: 5-Year / 8-Year / 10-Year Cycle For government procurement projects, Total Cost of Ownership (TCO) is a key decision-making metric. Below is a TCO analysis for the delivered blue license plate, 5 m³ sludge suction trucks, based on reference pricing from Chengli’s knowledge base (approximately RMB 109,000–128,000 per unit, tax-inclusive landed price), covering 5-, 8-, and 10-year cycles. 1. Initial Acquisition Cost Per local procurement practice, the landed price (including tax, registration, and first-year insurance) for each blue license plate, 5 m³ sludge suction truck is approximately RMB 117,000. For three units, the total is ~RMB 315,000 — below the budget ceiling. 2. Operational and Maintenance Costs (Estimated for 5/8/10 Years) Sludge suction trucks primarily operate in humid, highly corrosive sewer environments; key wear components include tank anti-corrosion coatings, hydraulic systems, vacuum pumps, and sealing elements. Based on Chengli’s after-sales data and operational experience with similar vehicles: - Annual fuel cost (diesel): ~RMB 12,000/unit (calculated at 50 km/day average operation and 15 L/100 km fuel consumption); - Annual maintenance cost (including engine oil, filters, hydraulic fluid): ~RMB 3,000/unit; - Annual repair cost (including replacement of wear parts): ~RMB 5,000/unit (lower during the first 5 years; increases progressively between years 8–10). Below is the estimated TCO per vehicle (in RMB ten-thousands): | Item | 5-Year Cycle | 8-Year Cycle | 10-Year Cycle | |-------------------|--------------|--------------|----------------| | Acquisition Cost | 10.5 | 10.5 | 10.5 | | Fuel Cost | 6.0 | 9.6 | 12.0 | | Maintenance Cost | 1.5 | 2.4 | 3.0 | | Repair Cost | 2.5 | 6.0 | 10.0 | | **Total TCO** | **20.5** | **28.5** | **35.5** | As shown in the table, the total cost over a 10-year cycle is approximately 3.4 times the initial acquisition cost, with repair expenses rising significantly after year 8. Therefore, it is recommended that government purchasers prioritize a 5–8 year service life and conduct a vehicle renewal assessment at the end of year 8. III.
