Excavate a 5m x 5m x 5m pit with a mini excavator

I want to dig a pit measuring 5m x 5m x 5m.

For this, I want to rent a mini excavator, but all the mini excavators have a max digging depth of about 2-2.5 meters.

What is the best way to do this, does anyone have experience with something like this?

Maybe there is a video that I haven't found, or some kind of instruction??

I somehow have to dig a ramp or something so that I can get into and out of the pit!

I am very grateful for any good tips!

That is most likely life-threatening. I would avoid it.

phew 5 meters is already quite a lot. I wouldn't experiment there. How about the groundwater?

That does not matter. Since the OP already asks such a question, they probably have no knowledge of [Verbau] of excavation pits. A [Verbau] is required from 1.25m onwards, and from this depth there is a danger to life and limb.

So the groundwater is probably not the problem!

I have already worked with a mini excavator, but not that deep.

I have already rented the excavator for next week, I want to do it myself.....

I have already done so much myself, I will manage this too.........

I'm just not sure how to do it with the loading ramp.......

Well, if the pit at the top is 25mx25m, the project might possibly be survivable.

Seriously... 5m depth calls for a professional company.

HANDS OFF! THIS ENDS FATALLY!!!
