Can crusher project.

Question for you mechanical geniuses? Thinking about making a can crusher. I have a 2 3/4" hydraulic cylinder. Can I use a hydraulic cylinder on air without any changes?
I would run compressor at 90 PSI. I calculate that I would be excreting 388 PSI on the can. Enough to crush it? ​

 

I have always wanted to build this can crusher.

 

I love redneck ingenuity!

 

I’ll watch the video later but I crush mine with a 2’ piece of 4x4.

 

I wonder how many MPG that rig gets?

 

Just watched it.. Holy moley I’d end up losing a body part in that thing!

 

90 psi is insane, I build halloween props and rarely use more than 20 psi.

 

388PSI is roughly 2 guys standing on the can, no ?


You'll need to lubricate it like you would a nail gun
.

 

Depends what they weigh...

 

what is the saying?

it is all fun until somebody gets hurt.

90psi at 2.75 dia. is entering bomb territory.

 

I know...you are right...just funnin around a little. I don't think anybody was taking my Tim Allen meme as official endorsement of mega PSI can crusher...

 

I agree but just in case the OP does not realize it I wanted to throw it out there. I fI didn't and read a thread next week that the OP blew up his tool I would feel terrible.
Now back to the can crusher, what voltage? 220, 440.......................

 

480 3ph...

 

Years and years ago i worked at a scrap yard, i was a non ferrous buyer, we had a industrial can crusher, huge, had the same thing in side of it. 2 tires that spun into eachother.
