CLW: Refers to the manufacturer, Chengli Special Automobile Co., Ltd. (often abbreviated as CLW). They are a major Chinese special vehicle manufacturer.

4x2: Indicates the truck's drive configuration. It means the vehicle has four total wheels (or wheel ends) and two of those wheels are driven (usually the rear axle). This is a common setup for light and medium-duty trucks.

Refuse/Rubbish/Waste Compactor/Collector/Transport/Transfer: These are all terms that describe the function of the vehicle, which is to collect solid waste, compact it to increase its density, and then transport it, often for transfer to a larger facility or a final disposal site.

Compactor/Compressed Garbage Truck: The primary function is to collect and compact waste to increase capacity and reduce the number of trips to a disposal site.

• Function: Rear-loading compactor for efficient collection, compression, and transportation of municipal solid waste (MSW).
• Capacity: Commonly available in smaller to medium sizes for the 4x2 chassis, such as 4 CBM, 5 CBM, 8 CBM, or 10 CBM (Cubic Meters).
• Compaction System: Equipped with a hydraulic system to compress the garbage, typically achieving a compaction ratio of 1:3 to 1:4 (reducing volume significantly).
• Operation: Features include automatic loading, compressing, and discharging, often controlled by a computer control system (like PLC) with both automatic and manual modes for dual safety and flexibility.
• Loading Mechanism: Usually a rear-loader with an optional bucket lifting system (for various bin sizes) or a hopper for manual loading.
• Sealing: Designed with a fully sealed dustbin and a sewage water collection tank to prevent leakage and secondary pollution (odor, liquid run-off) during transport.
• Chassis: Typically a 4x2 chassis with a suitable engine (e.g., Dongfeng, Isuzu chassis and engine variants) to meet local emission standards (e.g., Euro III, Euro V, Euro VI).

• Rear Loading: Garbage is loaded from the rear of the vehicle.
• Hydraulic System: The compaction and unloading operations are powered by a hydraulic system.
• Sealed/Leakage Proof Design: The vehicle is fully sealed to prevent the leakage of garbage and sewage, which helps to solve the problem of "secondary pollution."
• Sewage Water Collection Tank: A dedicated tank is included to collect liquid waste during the compression and transport process.
• Automatic Operation: Many models feature a computer control system for automated loading, compressing, and discharging.
• Manual Operation: A manual override system is available for safety and backup.
• One-Person Operation: The design allows for a single operator to manage the collection and unloading processes, reducing labor intensity.

• Chassis: Typically built on a Chinese chassis brand like Dongfeng, Sinotruk HOWO, Foton, or FAW.
• Drive Type: 4x2 (4 wheels, 2 of which are powered), indicating good maneuverability for urban environments.
• Capacity: Varies, but common capacities range from 5 CBM (cubic meters) to 20 CBM. The compression ratio can be up to 1:2.5, significantly increasing the effective load.
• Engine: Diesel engine, with varying horsepower and emission standards (e.g., Euro 3, Euro 4, Euro 5).
• Transmission: Manual.
• Safety Features: Often includes safety measures like an emergency stop button, safety braces, and interlock switches.

• High Compression Ratio/Large Load: Efficiently compacts waste to maximize the amount of garbage collected per trip.
• High Automation: Reduces the physical labor required for sanitation workers.
• Environmental Protection: The sealed design and sewage collection system prevent pollution.
• Good Economy: Increased efficiency leads to lower fuel consumption and operational costs.
• Versatility: Can be equipped with different lifting and turnover mechanisms for various types of bins.

CLW 4x2 Refuse Rubbish Transport Collector Transfer Waste Compactor is a type of garbage truck known for its compression capabilities. As a product from Chengli Special Automobile Co., Ltd. (CLW Group), its specific details can vary depending on the chassis brand (e.g., Dongfeng, Isuzu) and the volume capacity.

Garbage Bin Body: Constructed from high-quality carbon steel (e.g., Q235, Q345) with specified thickness (e.g., 4 mm side, 5 mm bottom) for durability. It is a sealed body design.

Sealing: The entire vehicle is typically fully sealed to prevent leakage and secondary pollution. It includes a dedicated sewage water collection tank to collect liquids generated during the self-compression and dumping process.

Compaction Mechanism: Achieved through a hydraulic-driven push plate and scraper system in the rear hopper to compact waste into the main body.

Hopper/Filler: The rear part of the compactor body where garbage is loaded and compressed, often designed to be leak-proof.

Garbage Feeding/Unloading Cycle Time: Fast operating cycles, with feeding often ≤25 s and unloading around 15 to 40 s.

III. Hydraulic and Control System
Technology: Uses electro-hydraulic integration technology with an automatic control system for machine, electricity, and hydraulic functions.

Control System: Features a computer control system (sometimes PLC-based) for one-key, full-automatic operation, as well as a manual operation system for backup.

Dual Operation System: Includes electric control panels at the rear of the vehicle (on both sides) and often controls inside the cab.

Hydraulic System: A powerful system with components like a hydraulic pump, multi-way control valves, and cylinders (sliding, scraping, lifting, pushing) to achieve high compression force.

IV. Auxiliary Features
Waste Bin Turning Mechanism: Optional mechanisms can be installed at the rear to automatically lift and dump various standard-sized bins (e.g., 120 L, 240 L, 660 L plastic or iron barrels).

Single-Person Operation: Designed for one sanitation worker to complete the entire loading and unloading process, which reduces labor intensity.

Safety: Modern designs often include safety interlocks, emergency stop buttons, and other features.

Location and History: The company is headquartered in Suizhou City, Hubei Province, which is known as the "Capital of China's Special Purpose Vehicles." It was established in September 2004.
