Introduction
Hydraulic cylinders play a crucial role in various machinery, providing the necessary force for movement and operation. One key aspect of hydraulic cylinders is the self-locking mechanism, which enhances safety and functionality in different applications.
Self-Locking Mechanism
Self-locking cylinders are designed to prevent accidental sliding or displacement when the hydraulic cylinder is at rest. This mechanism ensures stability and safety in high-load conditions, improving overall equipment performance.
Design and Construction Characteristics
- Welded Structure: High-strength welding process for durability and pressure resistance.
- Integrated Design: No removable connections, reducing leakage risk.
Self-Locking Mechanism

- Mechanical Self-Locking: Prevents accidental movement through a mechanical structure.
- Hydraulic Self-Locking: Hydraulic system design prevents reverse flow under load.
Working Principle

The self-locking welded hydraulic cylinder operates by utilizing mechanical or hydraulic self-locking mechanisms to maintain position stability and prevent accidental movement. This ensures safety and reliability in various applications.
Types and Configurations
There are three main types of self-locking welded hydraulic cylinders, each designed for specific applications and requirements. These cylinders offer unique features and capabilities to meet diverse industry needs.
