Hydraulic Jack Lifting Cylinder

Hydraulic jack cylinders provide powerful linear lifting force in compact packages, delivering capacities from 2 to 500 tons with precision control. These robust actuators feature reinforced steel construction and precision-ground pistons that maintain stability under full load, while their self-locking mechanisms prevent unintended lowering. The single-acting piston design offers simple operation with manual or power pump options, achieving lift heights up to 500mm in standard models. Their portability and standalone operation make them indispensable for field applications where fixed power sources are unavailable.  

 

Critical applications include bridge bearing replacement where synchronized jacking systems maintain millimeter-level alignment during structural lifts. Heavy equipment maintenance relies on their ability to safely elevate bulldozers and mining trucks for undercarriage servicing. Construction teams use them for precise building column positioning during installations, while manufacturing plants employ high-precision versions for die change operations. Emergency rescue operations depend on compact spreader jacks that combine lifting and spreading functions in confined spaces.  

 

Specialized variants include:  

• Low-profile jacks (50mm height) for vehicle frame lifting  

• Multi-stage telescopic models for extended reach  

• Anti-corrosion designs for marine applications  

• Explosion-proof versions for hazardous environments  

 

Modern advancements incorporate load cells for real-time force monitoring and wireless control systems for remote operation. The cylinders' ability to generate immense force from compact hydraulic power units makes them irreplaceable for maintenance, construction, and industrial positioning tasks where conventional lifting equipment cannot access or lacks sufficient power.
