Introduction to Locking Single-Acting Hydraulic Cylinder
Subtitle: Understanding the Key Features
The locking single-acting hydraulic cylinder is a specialized hydraulic component that operates under hydraulic pressure in one direction and features a locking mechanism to prevent movement in the absence of pressure.
Design and Construction Characteristics
- Locking Mechanism – Safety: The main feature of the locking single-acting hydraulic cylinder is its locking mechanism, which ensures the piston remains in a safe position even when hydraulic pressure is lost, preventing accidental retractions.
- Variety: The design of the locking mechanism can be customized based on specific application needs, utilizing spring-loaded locking devices, pin locks, or other forms of mechanical locks.
- Compact Structure – Space Optimization: These cylinders are designed to be compact, making them suitable for use in space-limited environments and various equipment and machinery.
- Precision Manufacturing – High-Precision Machining: Components undergo high-precision machining to ensure good fit and sealing performance, minimizing the risk of leakage.
Working Principle

The single-acting mechanism of the locking cylinder extends the piston outward when hydraulic oil is pumped into the chamber. The retraction is prevented by a locking mechanism, either mechanical or hydraulic, ensuring the load remains safe even in the absence of hydraulic pressure.
Types and Configurations
There are three main types of locking single-acting hydraulic cylinders, each offering unique configurations tailored to specific applications.
Benefits

- Enhanced Security: The locking mechanism reduces the risk of accidental retractions, enhancing operator safety.
- Reliability: These cylinders are designed to operate effectively under high loads and varying environmental conditions, ensuring consistent performance.
- Simplicity: Easy to operate and maintain, making them user-friendly for a wide range of applications.
Applications
- Construction Equipment: Commonly used in cranes, hoists, and lifts to securely hold heavy objects in place.
- Manufacturing: Utilized in presses to maintain pressure during material forming processes.
- Transportation: Stabilizers and jacks for vehicles to ensure safety during maintenance or transport.
