# 9-Cubic-Meter Cleaning Truck: An Efficient Tool for Urban Sanitation In the field of urban cleaning, the 9-cubic-meter cleaning truck stands out as a reliable assistant for maintaining clean streets, with numerous highlights in operational efficiency, cleaning capability, intelligent safety, and durability. ## I. Efficient Operation with Uninterrupted Endurance 1. **Large-Capacity Tanks**: The 9-cubic-meter cleaning truck is equipped with a clean water tank (approximately 4-5 cubic meters) and a garbage bin (approximately 4-5 cubic meters). The large-capacity clean water tank reduces the frequency of refills, enabling 3-4 hours of continuous operation on urban large-area cleaning tasks after a single refill. This is particularly suitable for concentrated cleaning before morning rush hours, making full use of early morning hours to efficiently clean large road surfaces. The large garbage bin also minimizes frequent unloading time, allowing a daily cleaning area of 80,000-100,000 square meters. 2. **Wide Operational Coverage**: The vehicle achieves an operational width of 3.2-3.5 meters through the collaboration of mid-mounted dual sweeping discs, a wide suction nozzle, and auxiliary high-pressure side spray rods. This allows covering a wider road surface in one pass. Combined with a reasonable operating speed, it can clean 10,000-12,000 square meters per hour, significantly reducing operational time and improving overall cleaning efficiency compared to smaller cleaning equipment. ## II. Powerful Cleaning with Versatile Performance 1. **Multi-Functional Integration**: The truck integrates multiple functions, including road washing, sweeping, curb cleaning, and spray dust suppression. For road washing, the high-pressure water pump delivers strong water pressure (typically 10-16 MPa), quickly removing oil stains, accumulated dirt, and stubborn grime. The sweeping discs, made of wear-resistant alloy bristles, penetrate gaps to gather gravel, sediment, and other debris toward the suction nozzle. The curb cleaning function targets dead corners of curbs to ensure tidy road edges, while the rear fog cannon effectively suppresses dust, improving air quality for comprehensive cleaning results. 2. **Deep Cleaning Capability**: It adopts a combined design of "mid-mounted dual sweeping discs + wide suction nozzle + high-pressure side spray rods + rear fog cannon". The mid-mounted dual sweeping discs (diameter 600-700 mm) feature adjustable rotation speed to adapt to different road conditions. The 2.2-2.4-meter-wide suction nozzle, equipped with built-in high-pressure water spray rods, achieves over 95% recovery rate of garbage and sewage through the synergy of high-pressure water and strong suction. The V-shaped arrangement of high-pressure side spray rods efficiently channels cleaned sewage and garbage toward the suction nozzle, ensuring no residual dust or stagnant water on the road. ## III. Intelligent Enhancement for Safety and Reliability 1. **Intelligent Monitoring and Alarming**: Equipped with an intelligent central control system, it uses sensors to real-time monitor key parameters such as water tank level, garbage bin fullness, and hydraulic system pressure. When the clean water tank is low, the garbage bin is nearly full, or the hydraulic system malfunctions, the system immediately issues voice alerts to remind the operator, preventing equipment damage from dry running or leakage and ensuring stable operation. 2. **Safety Protection Devices**: It features a reverse protection device: when reversing during operation, the intelligent control system automatically stops work and quickly retracts the sweeping discs, suction cup, and side spray rods to prevent collision damage. The sweeping discs also have automatic obstacle avoidance—they retract when encountering obstacles and resume operation after passing, reducing equipment failure rates, protecting the vehicle, and enhancing operational safety. ## IV. Durable Construction with Easy Maintenance 1. **High-Quality Materials and Structure**: The clean water tank and garbage bin are made of high-quality stainless steel or high-strength corrosion-resistant steel. For example, the garbage bin uses 304 stainless steel, which is sturdy, leak-proof, and highly corrosion-resistant, extending the tank’s service life to 8-10 years. The tank structure is optimized—for instance, the garbage bin’s interior features a large flat slope design with a dumping angle of 45-50 degrees, facilitating easy waste discharge. 2. **User-Friendly Maintenance Design**: Key components are strategically arranged for easy inspection and repair. For example, the garbage bin includes a built-in high-pressure flushing device to automatically clean its interior after unloading, reducing manual maintenance. The hydraulic system uses well-known brand components to ensure precise and smooth operation of sweeping discs, suction nozzles, and other parts with long maintenance intervals. Wear parts like brushes and nozzles are easy to replace, lowering daily maintenance costs and time.
