I am quite interested in the tech they use for the rams .. personally IMV this looks like a lot of trouble .. I mean how often do you get failures with a washing machine ?
.. I'm not convinced

Be interesting to see how smoothly it digs with the electric controls .Comment

I believe there's great potential. It would be good to work in an exhaust fume free environment. It certainly is not good for health to inhale tons on particulate emissions from old excavator engines. Some of us do that for thousands of hour in a year. Equally, would prefer listening to music and birds singing rather than the raw diesel noise.
efficiency is another very important factor in case you want to earn some money...:)Comment

Looks very interesting. I do a fair few jobs indoors or very confined areas. All electric would be a great improvement for me. If it can genuinely work 8 hard hours per charge and costs less than the equivalent diesel what is not to like?
Didn't understand "The hydraulic architecture has also been replaced with electric architecture which incorporates electromechanical linear actuators that help to optimize the transmission chain". Are they saying the rams are not hydraulic, but wound in and out by electric motors?

Yes and thats the bit I'm interested in, because when you think about how many times a ram get stroked on a normal day, theres going to have to be something very clever and reliable in there to make this thing viable, and they claim it has the same power ? ... Id have thought keeping the rams hydraulic would have been the way forward as its so reliable.Originally posted by Grahams View PostPlease don't PM me for plant advice.. thanks ..

I suppose as it is a concept machine they are trying everything different, but in reality hydraulics work very well, why mess about with them?Originally posted by Muz View PostComment

even though hydraulics work well, it still looses a lot of energy due to pump that runs all the day. Th electric rams use energy only when actually doing something useful.Originally posted by Grahams View Post
That explains why the battery is well enough for the workday.
I have been following development of electric drive trains and most likely the same development happens in work machines that we have seen in electric cars. I believe that all big manufacturers are testing electric concepts and we will see some commercial products within 5 years.Comment

Yes that was my thought .. a pump running constantly will use a hell of a lot of power, With todays stop/start tech in cars though, I thought they could have reduced that to a useable level ?. I just cant imagine a bunch of electric rams being anywhere as responsive as a good hydraulics system. I mean a straight up and down cylider can only be a worm or ratchet and pinion type drive ? any other guesses ? .. maybe its a small pump on every ram keeping it hydraulic ?Originally posted by Mattir View PostPlease don't PM me for plant advice.. thanks ..

could well be, looking at the pix MuzOriginally posted by Muz View Post
if they were electro mechanical, screw type actuators, they'd have to be much longer, unless they're multi stage acme thread type screws, enclosed in those outers .... can't see anything other than hydraulic fitting the dimensions, otherwise
..... or being fast enough .... I'd be concerned about cable life on the crowd ram actuator's supply, where it passes through the dipper's articulation point. 
They're some cables those
If it's got tracks, wheels, t*ts, or an engine, at some point it's gonna give you trouble!!

that would appear to be what they are using. Good find.Originally posted by Mattir View Post

yea but whats inside them ? I looked through several links and found nothing .. as seasoned plant men... we know what the f..k works ?Originally posted by v8druid View PostSpot on find there Boyo

Hummm, so I wonder if anyone makes an electric rock breaker ., and tilty / turny hitch .Comment
