The compression-type garbage truck consists of a sealed garbage body, a hydraulic system, and an operating system. Its main components include the body structure, compression-filling mechanism, rear-loading device, and operating mechanism. The cargo body is fully sealed; garbage is automatically compressed and hydraulically dumped under electronic control. Waste is loaded through the rear loading opening, crushed and compacted into the body, while all leachate generated during compression is collected in a dedicated wastewater tank—effectively eliminating secondary pollution during transportation and significantly reducing the physical workload of sanitation workers while enhancing waste collection and transfer efficiency. Compression garbage trucks feature prominent characteristics and powerful functionality, offering numerous advantages: 1. **Simple and user-friendly waste collection**: Effectively eliminates haphazard street-side waste dumping in urban areas and prevents secondary pollution. 2. **High compression ratio and ultra-large payload capacity**: Maximum crushing pressure reaches up to 12 tons; payload capacity is approximately 2.5 times that of non-compacting garbage trucks of equivalent gross vehicle weight rating (GVWR). 3. **Electronically controlled automated operation**: The hydraulic system employs a modular control valve bank and imported computerized control system. The entire loading, compression, and unloading cycle can be completed by a single operator—improving work efficiency, reducing labor intensity for sanitation staff, and significantly enhancing urban aesthetics. 4. **Intelligent fuel-saving control**: When auxiliary equipment operates independently, the computerized control system automatically regulates engine throttle to optimize fuel consumption. 5. **Dual-safety operating system**: The operational system supports both electric control and manual override, ensuring uninterrupted performance even if one mode fails. 6. **Multiple optional lifting mechanisms**: A variety of compatible lifting mechanisms are available to meet diverse operational requirements across different working environments. The hydraulic system governs the entire garbage processing workflow—and is also the most failure-prone component. As compression garbage trucks perform the dirtiest and most physically demanding tasks, minor malfunctions inevitably occur over extended operation. Given their high technical complexity, component repair or replacement is challenging and costly; therefore, no issue—however minor—should be overlooked. Regular maintenance, inspection, and servicing are essential to significantly extend the service life of compression garbage trucks. **Common Hydraulic System Failures and Troubleshooting Methods for Compression Garbage Trucks** For purchasing garbage trucks, please trust Hubei Chengli Special Purpose Vehicle Co., Ltd.
