Enhancing Safety and Functionality with Self-Locking Welded Hydraulic Cylinders
Introduction
Hydraulic cylinders play a crucial role in various machinery by converting hydraulic energy into mechanical force. Among these cylinders, self-locking mechanisms are key to improving safety and functionality, ensuring stability and preventing accidents.
Design and Construction Characteristics
- Welded structures: High strength welded processes guarantee overall strength and tightness, suitable for heavy loads and high pressure.
- Integrated design: No removable connections reduce leakage risks and enhance reliability.

Self-Locking Mechanism
- Mechanical self-locking: Prevents accidental sliding or displacement when the cylinder is at rest.
- Hydraulic self-locking: Ensures the hydraulic oil cannot flow in reverse under load, maintaining stable cylinder position.
Working Principle

The self-locking welded hydraulic cylinder operates through mechanical or hydraulic locking to prevent accidental movement, ensuring safety and stability during operation.
