Introduction
In the world of machinery and equipment, the role of hydraulic cylinders cannot be overstated. These essential components play a crucial role in providing the necessary force to move heavy loads and operate various types of machinery. One key aspect of hydraulic cylinders is the self-locking mechanism, which enhances safety and functionality in a variety of applications.

Self-Locking Mechanism
A self-locking cylinder is designed with a mechanism that prevents accidental sliding or displacement when the hydraulic cylinder is at rest. This feature is essential in maintaining stability and preventing potential accidents, especially in high-load or tilt operations.
Design and Construction Characteristics
- Welded Structure: High-strength welding ensures overall strength and tightness, suitable for heavy loads.
- Integrated Design: No removable connections reduce the risk of leakage and increase reliability.

Self-Locking Mechanism
- Mechanical Self-Locking: Prevents accidental movement through a mechanical structure.
- Hydraulic Self-Locking: Hydraulic system design prevents hydraulic oil flow in reverse under load.
Working Principle
The self-locking welded hydraulic cylinder operates through a combination of mechanical locking and hydraulic maintenance, ensuring the piston remains in the desired position to prevent accidental sliding or movement.
Types and Configurations
There are three main types of self-locking welded hydraulic cylinders, each offering unique features and configurations for specific applications.
Advantages
- Safety: Prevents accidental movement and enhances operator and equipment safety.
- Reliability: Holds position under load, reducing maintenance needs.
Performance Features
- Self-Locking Function: Prevents accidental sliding and improves safety.
- High Strength and Durability: Welded structure and wear-resistant materials ensure longevity.
Application Scenarios
