יישומים
The multistage hydraulic cylinder is widely used in:
- Construction machinery
- Lifting platforms and jacks
- Dump trucks and hydraulic lifting systems
- Industrial presses
- Mining equipment
- Marine and offshore equipment
- Heavy equipment maintenance
- Bridge and infrastructure projects
Advantages Compared to Single Stage Cylinder
- Longer stroke in limited space
- More compact retracted size
- Higher flexibility for installation
- Suitable for mobile equipment
- Better efficiency in multi-stage lifting systems
עקרון עבודה
The multistage hydraulic cylinder works by sequential oil pressure activation. Each stage extends one by one, starting from the largest diameter stage to the smallest. This allows long stroke output while maintaining compact structure when retracted.
בקרת איכות
Each cylinder is tested before shipment:
- Pressure testing up to 1.5× rated load
- Leakage test
- Stroke smoothness test
- Surface hardness inspection
- Seal durability test
Why Choose LONGLOOD Multistage Hydraulic Cylinder?
- Factory direct supply
- OEM/ODM customization support
- Strict quality inspection system
- High pressure performance stability
- Fast global shipping support
- Technical engineering support
שאלות נפוצות
1. What is a multistage hydraulic cylinder used for?
It is used for lifting or pushing applications where long stroke is needed in a limited installation space.
2. What is the difference between telescopic and single hydraulic cylinder?
A telescopic cylinder has multiple stages that extend sequentially, while a single cylinder has only one piston rod.
3. Can you customize stroke length and tonnage?
כֵּן, we provide fully customized solutions including stroke, תְפוּסָה, mounting type, and pressure rating.
4. What pressure does this cylinder support?
Standard models support up to 700 בַּר (10,000 PSI).
5. Is OEM branding available?
כֵּן, OEM logo, packaging, and design customization are available.
