Подробности за продукта

Многоетажен хидравличен цилиндър

The Многоетажен хидравличен цилиндър, also known as a telescopic hydraulic cylinder, is designed for applications requiring long stroke with compact retracted length. It provides powerful linear force through multiple stages that extend sequentially, making it ideal for lifting, бутане, pressing, and heavy-duty industrial operations.

Manufactured with high-strength alloy steel and precision machining, our hydraulic cylinders ensure stable performance under high pressure up to 700 бар.

Приложения

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 бар (10,000 PSI).

5. Is OEM branding available?

Yes, OEM logo, packaging, and design customization are available.
