Introduction to Locking Single-Acting Hydraulic Cylinder For Telescopic Handlers
The locking single-acting hydraulic cylinder is a specialized component that works under hydraulic pressure in one direction and has a locking function to prevent movement in the absence of pressure. This unique feature ensures safety and stability in various applications where precise control is required.
Design and Construction Characteristics
The design of the locking single-acting hydraulic cylinder is focused on safety and reliability. The locking mechanism plays a crucial role in keeping the piston in place when hydraulic pressure is lost. It can be a mechanical or hydraulic lock, tailored to specific application needs.
Locking Mechanism – Safety
- The locking mechanism ensures the piston remains in a safe position even when hydraulic pressure is not present, preventing accidental retractions.
- Customizable design options include spring-loaded devices, pin locks, and other mechanical locks to meet specific requirements.

Compact Structure – Space Optimization
- Locking single-acting hydraulic cylinders are designed to be compact, making them ideal for space-limited environments.
- Precision manufacturing with high-precision machining ensures tight seals and reliable performance.
Working Principle
The single-acting mechanism of the hydraulic cylinder extends the piston when hydraulic oil is pumped into the chamber. The locking function, whether mechanical or hydraulic, prevents the piston from retracting under load, ensuring safety even in case of pressure loss.
