The Versatile Hydraulic Solution: Spring-Return Single-Acting Hydraulic Cylinder For Loading Ramps
Expanded Introduction to Spring-Return Single-Acting Hydraulic Cylinder

Spring-Return Single-Acting Hydraulic Cylinder is a hydraulic cylinder that utilizes hydraulic oil to expand the piston. When pressure is released, the built-in spring automatically retracts the piston.
Design and Construction Characteristics
Single-Acting Structure
- Operates in one direction through hydraulic oil pressure
- Return depends on the built-in spring
Spring Selection
- Appropriate spring selection ensures quick and complete reset
Sealing Design
- High-quality sealing materials prevent hydraulic oil leakage
Strength and Durability
- Material selection considers strength to withstand high pressure
Construction and Assembly Process
The assembly process requires precise docking of components to reduce friction and wear. Welding and mechanical connections must be strong to prevent oil leakage. Testing ensures normal operation in actual work.
Working Principle
The single-acting mechanism extends the piston with hydraulic oil pressure and retracts it with the spring mechanism.
Types and Configurations
Spring-Return Single-Acting Hydraulic Cylinders come in three types with different configurations, each suitable for specific applications.
