New 2025 Isuzu NPR waste compaction truck

Let's learn about the structure of high-quality ISUZU garbage rear loader truck

——Chassis system: Isuzu NPR garbage compactor truck, equipped with Isuzu special engine 4HK1 model, 190 horsepower engine, gearbox (such as MSB five-speed gearbox) and drive system, supports National V/National VI emission standards. Chassis configuration includes air brake, ABS, original air conditioning, remote control key, etc. to ensure driving stability and convenient operation.

——Garbage compartment: The compartment is made of high-strength materials, high-quality carbon steel such as Q345 manganese steel, and is formed by fully sealed welding. The volume ranges from 4 cubic meters to 20 cubic meters. The compartment design includes an arc structure, a two-way compression push plate, a sewage tank (volume ≥ 200L) and an anti-leakage sealing device to effectively prevent secondary pollution.

——Hydraulic system: It consists of a fuel tank, an oil pump, a multi-way valve, a hydraulic cylinder, a pipeline, etc. The hydraulic pressure is usually set to 16Mpa, and the power is obtained from the engine through the power take-off to drive loading and unloading, compression, lifting and other actions.

——Loading and unloading and compression mechanism: Loading mechanism, rear flip bucket hanging mechanism can adapt to 240L or 660L standard trash cans, realize one-button automatic loading, and complete single garbage dumping within 15 seconds. Compression mechanism, push shovel and scraper compress garbage in both directions, the compression ratio can reach 1:3, and the peristaltic compaction function controlled by PLC can increase the loading capacity.

——Control system: adopts electromechanical and hydraulic linkage control, supports electronic control in the cab, wireless remote control and manual operation. PLC programming realizes automated operation (such as automatic throttle control, cycle compression), integrated operation, and improved efficiency.

What high-quality manufacturing processes are needed?

1. Materials and welding processes

——Strength steel: The box and key components use Q345 manganese steel or high-quality carbon steel with a thickness of 5mm. The structural strength is ensured by a fully sealed full welding process.

——Lightweight design: The box beam plate structure is adopted to reduce the dead weight while improving the load-bearing capacity.

2. Hydraulic system integration

——Precision adjustment: Hydraulic components (such as multi-way valves and cylinders) must be strictly matched, and the pressure valve (16Mpa) must be adjusted before leaving the factory to ensure system stability.
——Leakage prevention treatment: The pipeline uses high-density hydraulic oil pipes, and the British DLI sealing ring is used at the interface to reduce the risk of leakage.

3. Sealing and anti-corrosion process

——Sewage tank design: Large-diameter discharge ports prevent blockage, and the inside of the box is lined with stainless steel or coated with epoxy coal tar anti-corrosion layer to extend the service life.

——Post-welding treatment: Glue the welding parts and spray water-based paint to enhance rust prevention and adhesion.

4. Testing and quality inspection

Before leaving the factory, it must pass load testing (such as compression cycle, unloading stability), sealing testing and road suitability verification to ensure compliance with environmental protection and safety standards.
