JLG 450 AJ safety question

[bowser]

As I get a little older, I have gotten more cautious. I have often wondered what would happen if a hydraulic line to the main boom, secondary boom or jib were to burst, would the lift just crash to the ground or (as I hope) is there a sufficient back-up system where I don't need to worry about this. The hoses all look good but this question still enters my mind often.

They've all got holding valves on the cylinders. Blow a line it should stay in place.

Thank you 92U 3406. That does help me to feel better considering that this type of thing is your job. I appreciate your response.

On the flip side though you will likely be stuck in the air if a line does go. Also be aware that if a holding valve starts weeping a lot out the vent hole near the end that it is starting to fail and should probably get replaced.

Yep, but hey, better than rapid re-entry to earth. Keep your cell phone with ya.
