Maombi
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
Working Principle
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.
Quality Control
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
FAQ
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?
Yes, we provide fully customized solutions including stroke, tonnage, mounting type, and pressure rating.
4. What pressure does this cylinder support?
Standard models support up to 700 bar (10,000 Psi).
5. Is OEM branding available?
Yes, OEM logo, packaging, and design customization are available.
