SUMMARY

Connecting two hydraulic jacks in parallel is feasible, allowing both to operate simultaneously when one is pumped. This method ensures that both jacks experience the same pressure, which is critical for balanced lifting. However, it is essential to install shut-off valves for individual control over each jack to manage differing loads effectively. For practical applications, consider using hydraulic lift tables or hydraulic platforms commonly found in trucks for similar lifting needs.

PREREQUISITES
  • Understanding of hydraulic systems and principles
  • Familiarity with hydraulic jacks and their operation
  • Knowledge of fluid dynamics in parallel systems
  • Experience with hydraulic components like shut-off valves
NEXT STEPS
  • Research hydraulic system design for parallel jack connections
  • Learn about the installation and function of shut-off valves in hydraulic circuits
  • Explore hydraulic lift tables and their applications in lifting scenarios
  • Investigate load balancing techniques in hydraulic systems
USEFUL FOR

Engineers, technicians, and DIY enthusiasts involved in hydraulic system design, maintenance, or applications requiring synchronized lifting mechanisms.

it is possible to connect two hydraulic jacks together? i want to lift an inclined board using two hydraulic jacks at both ends of the board. is there a way that i can connect two hydraulic jacks together so that when i pump one of the jacks, the other is also being pumped. Any ideas how to lift the inclined board will also be helpful. thanks.

Why not split the fluid feed into two, i.e. connect them in parrallel. You will have no control over them separately though.
 


I've manifolded jacks together many times, lifting as much as 800 tons.

But they will all see the same pressure. This can be a problem if they do not also see the same load. So install a shut off valve in front of each jack to control the fluid going to that jack individually.
 


Well... you could hook them all to the same pump.
However - there are simpler ways: look up "hydraulic lift table" or just look at the hydraulic platforms at the back of trucks.

Multiple posting the same question across PF forums is against the rules here (and you have been previously warned about this). Check your PMs.

I have merged the 3 threads into this one.
