Zibo Municipal Government Procurement Case: 24 m³ Sinotruk Sludge Tipper Truck — In-depth Analysis of Chengli’s Winning Bid Solution. In municipal sanitation and industrial sludge transportation, the 24 m³ Sinotruk-chassis sludge tipper truck has become a procurement necessity for many local governments due to its large capacity, high load-bearing capability, and adaptability to complex operating conditions. Recently, a municipal sanitation department in Zibo City, Shandong Province, conducted a public tender for a batch of 24 m³ sludge tipper trucks. Chengli Special Purpose Vehicle Co., Ltd. secured the contract with its proven product solution, competitive pricing, and comprehensive after-sales service system, successfully delivering the entire batch. This article provides procurement entities with a detailed reference covering case background, winning bid solution, model parameter comparisons, cost advantages, and frequently asked questions. I. Case Background: Upgraded Sludge Transportation Requirements in Zibo Municipality As an industrial hub, Zibo’s wastewater treatment plants and industrial enterprises continue to generate increasing volumes of sludge. Aging vehicles—characterized by small capacity, non-compliant emissions, and poor sealing—can no longer meet increasingly stringent environmental protection requirements. The municipal sanitation department plans to procure approximately 10 units of 24 m³ Sinotruk-chassis sludge tipper trucks, with a budget of around RMB 317,000–396,000 per unit (based on publicly available tender information), primarily for urban pipeline desilting, sludge transfer from wastewater treatment plants, and industrial solid waste transportation. Key tender requirements included: - Chassis: Sinotruk brand, compliant with China VI emission standards, and possessing high load-bearing capacity; - Body: Effective capacity of 24 m³, fully sealed cargo body with anti-leakage design, and stable hydraulic tipping system; - After-sales service: Nationwide chassis warranty; body covered by minimum 5-year or 100,000-km warranty; spare parts dispatchable within 24 hours; - Delivery timeline: Full delivery within 30 days after contract signing. II. Chengli’s Winning Bid Solution: Sinotruk Chassis + 24 m³ Sludge Tipper Body For this tender, Chengli Special Purpose Vehicle offered the CLW5310ZWXZ6 sludge tipper truck (officially approved model number by MIIT), built upon the Sinotruk Howo chassis—fully meeting all tender specifications. Key highlights of the solution include: 1. Chassis Configuration: Sinotruk Howo — Proven Reliability Equipped with the Sinotruk Howo ZZ1317N466GF1 chassis, powered by the MC07H.35-60 engine delivering a maximum output of 350 hp (257 kW), paired with a 10-speed transmission and compliant with China VIb emission standards. This chassis enjoys widespread adoption across sanitation and engineering vehicle applications, supported by an extensive network of authorized service centers—particularly dense across Shandong Province, where Sinotruk service stations cover all prefecture-level cities, ensuring fulfillment of the ‘nationwide chassis warranty’ commitment. 2. Body Design: 24 m³ Large Capacity, Fully Sealed & Leak-Proof The cargo body is fabricated from high-strength steel plates with internal dimensions approximating 7.2 m × 2.3 m × 1.5 m, yielding an effective volume of 24 m³. A hydraulically actuated sliding roof seal is installed at the top, while rubber sealing strips are added at the rear gate to prevent sewage leakage and odor dispersion during transport. The tipping system employs imported multi-stage hydraulic cylinders, enabling a tipping angle exceeding 50°, ensuring rapid unloading and minimal residue. Additionally, the interior surface is coated with corrosion-resistant material to withstand acidic/alkaline environments typical of sludge handling. 3. Environmental Protection & Safety Features Standard equipment includes an overflow alarm system.
