2、 Product classification and specialized models
| **Type** | **Function** | **Structural Characteristics** | **Applicable Vehicles** |
|-------------------|--------------------------------|----------------------------------------------------|-----------------------------------------|
| **Pushing Cylinder** | Compressing Garbage | Multi-stage telescopic sleeve type, oil ports at the rod end | Compression-type Garbage Truck |
| **Bucket Lifting Cylinder** | Unloading of the Bucket | Ear-ring installation, double-acting piston type | Bucket-hanging Garbage Truck |
| **Lifting Cylinder** | Elevating the Garbage Container | Piston type or piston type, high-pressure resistant design | Dumping-type / Arm-type Garbage Truck |
| **Scraping Cylinder** | Cleaning residual garbage | Compact structure, built-in buffer device | Sealed Garbage Truck |
3、 Core Performance and Technical Characteristics
1. High strength and lightweight
-By optimizing the structure through finite element analysis and adopting alloy steel cold extrusion technology, the weight is reduced by 15% -20% while the pressure bearing capacity reaches 31.5MPa.
2. Environmental adaptability
-Corrosion resistant coating (hard chromium plating+nickel plating) and ultrasonic cleaning process, suitable for garbage acid corrosion liquid and high salt spray environment.
3. Intelligent integration
-Optional hydraulic lock, balance valve, explosion-proof valve to prevent load loss of control; Support PLC remote monitoring of pressure and temperature.
4. Long life design
-The sealing system retains the piston rod oil film, reduces friction loss, and has a lifespan of ≥ 100000 cycles.
