How To Dissipate Stored Pressure In An Excavator- AskAPT #5

What is the number one thing that makes hydraulics dangerous to work with?
Pressure.
Without the high pressures used in these machines they simply wouldn’t work.
Usually when machines are turned off they are pretty safe to work on, right?
Well.. That’s unless there is trapped pressure that hasn’t been dissipated.
Now we don’t want you or any of your teammates to experience what it’s like to receive high pressure injuries, so that’s why I created this 5 minute video that runs through how to dissipate trapped pressure, and also in what situations certain methods do and don’t work.
It’s really straight forward and is something you can follow along with if you want to have someone talking you through it. (Although if you haven’t received training in hydraulics equipment before, we do not recommend attempting something like this without first receiving your basic training.)

So what is safe way to relief pressure from the rest of the system. How do you dissipate energy on joy stick or electronic control circuits?

Very fantastic demonstration, Thank you

I think systems now have an energy dissipating valve on the hydraulic tank, by activating it, where most oil trapped in the implements as capable of causing safety issue are routed back into the tank

An informative clip. How then do we work on the electronically controlled cylinder?

Great video Kyle!!!
