The wonderful world of bicycle can crushers

[slowmotion]

I stumbled on a use for old cranks. There are quite a lot of bush engineers out there using them.

Shame its got an electric motor on it though.
Do you think @Night Train would make one for @Arch?

Heath Robinson could do a more elegant job.

We've talked about it!

For work, we'd need something that could do a binbagful at a time. That hopper works very nicely, but we often have part crushed cans, so they'd probably foul the system. We've seen footage of something that works with two big rollers that would do. It would be human powered, of course.

I have some cans I would like to crush. I was thinking more along the lines of dumping the cans on my drive way, throwing a sheet of plywood on them and running over it with my truck. I need to check and see if there is a patent for it.

Something like a metal rolling/forming machine or an old fashioned mangle.

A pair of heavyweight boots and an aerobic stompin' session should do the trick. A work out and compacted cans - two birds killed with one stone. Takes up a lot less space too.

OR, place cans on the stairs, being careful to avoid falling, then run up & down until all the cans are flattened

Too much prepping!

 

[classic33]

Much excitement can be had in anticipation.

 

[numbnuts]

A lot of thought has gone into that

And watch them ping out from the ends as you drive onto the board and it tilts...

They roll like buggery given half a chance. You might do better if you gave each can a bit of a squash manually to stop it being so round. Or if you can contain them at the sides a bit...

I have seen some where the rollers are a pair of car wheels with tyres on.

I figured a flywheel, that is powered up by pedals, could drive the rollers and the cans can then be fed into it.
Alternatively a bale crusher where the 'hydraulic ram' is a power feed screw thread that is also pedal flywheel powered. It would have to be a fixed wheel so the thread can be reversed for the next bale.

An ingenious answer to a non existent problem. If you really need to crush your cans why not stamp on each can as you finish it
