Discussion Overview

The discussion revolves around the feasibility of connecting two hydraulic jacks to lift an inclined board. Participants explore various methods of linking the jacks, including potential configurations and practical considerations for operation.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests splitting the fluid feed into two jacks connected in parallel, noting that this would eliminate separate control.
  • Another participant shares experience manifold connecting jacks, indicating that while they can lift significant loads, all jacks would experience the same pressure, which could be problematic if loads are unequal. They recommend installing shut-off valves for individual control.
  • A different viewpoint proposes connecting the jacks to the same pump but also mentions simpler alternatives such as hydraulic lift tables or hydraulic platforms used in trucks.
  • Several posts reiterate the initial question about connecting two hydraulic jacks, indicating a lack of clarity or resolution on the topic.

Areas of Agreement / Disagreement

Participants present multiple competing views on how to connect the jacks, with no consensus reached on the best method or configuration.

Contextual Notes

Some participants emphasize the importance of load distribution and control in hydraulic systems, which may affect the effectiveness of the proposed solutions.

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.
