Traditionally we have been a nation of tinkerers and creators of new labour saving machines, the whole nanny state protect the plain stupid CE marking malarkey has stifled us. The big corporation mentality of pulling up the drawbridge after them has hamstrung the lifeblood of home grown manufacturing 😡

(that's rant of the day out of the way nice and early 😄)

Yes, It's done some work but wants a new powerpack, preferably a Deutz with a clutch setup and belt pulley if anyone knows of one.
Get a cheap 3 phase generator and a suitable sized 3 phase electric motor with a cheap Variable Frequency Drive. Use the 3 phase motor to drive the crusher and control it with the VFD.
Easy and simple solution with the benefit of a generator when not crushing. I'm assuming it's a jaw crusher, in which case if you're crushing concrete and bricks and not hard rock, the crusher doesn't need a lot of power to drive it. You can make do with a smaller generator and let the VFD handle high startup loads. Even better if you've got nearby 3 phase power in which case you'll save on fuel and wear & tear. It's so simple I've done it myself, crushing bricks and concrete from small demolition jobs :)

Rightly or wrongly I like ze oldschool.... We've no 3phase locally and tbh it's all extra faf and weight. She works grand with the 4 pot Ford D but the clutch is obsolete now and I'd like to do away with the radiator.

do it as well as you can,but learn to do it better
got offered a very cheap 3ph genny yesterday .... but 250KVA :oops: with an 8 pot RR turbo motor .... totally complete and running sweet .....:giggle: with a fully logged history :cool: .. stand by unit
'apparently' , I neither need nor want it :LOL: ...
will price up some tranny for it Monday .... ;)
's 3-4 t so off loading'd be no issues .... sneaking the bugger in might be though :(:censored: it's a bit of a lump

Not fussed on stand up controls with no cab operating the hiab 😢😢
I always think this about the remote controll demo machines, sod standing next to a hammer/muncher all day in the dust and crap!

I got a video from a mate that operates robo flails.
He was driving the landrover around behind the flail as it was raining
Kind of makes it a bit pointless.

With the amount of nasty dust generated by crusher I'd want any internal combustion engine to be as far away from the crusher as possible. Being aircooled means plenty of dust around the intimate engine bits which can set like concrete :oops:
Electric motors much cheaper and resistant to dust issues.

Dave,

Wise operators of those things stand up wind. Also have seen guys sitting in a chair with the controls on their laps. 😀😀😀😀

I assume on most sites you’d have to stand within a herras fenced box within a box 500 meters away from everything!

Could have a cab on tracks with Rops/fops and chair and glass and heater and control it from there maybe….
