man that is pretty slick! The one vid shows it lifting 2 gallons of something up. It looks pretty powerful.

The only info I could find is: It weighs about 62lbs Made mostly of steel runs on 4 x 7.2 volt batteries It must be a newly released item. |
Re: Powerful non-hydraulic Excavator from italy?
looks like it has some insane power in that last vid, can you guys do that with your hydraulic excavators?

Re: Powerful non-hydraulic Excavator from italy?
If it's not hydraulics what is it?
|
Re: Powerful non-hydraulic Excavator from italy?
Could be screw drive cylinders I think
|
Re: Powerful non-hydraulic Excavator from italy?
I'm pretty sure they are screw drive, which wouldn't be hard to do with motors like these. Not sure on the torque of these but I seen some the other day somewhere that would work for this purpose. This is a good buy on these Maxon motors.

Re: Powerful non-hydraulic Excavator from italy?
If it were screw drive wouldn't the cylinder rams have threads on them or am I missing something?
|
Re: Powerful non-hydraulic Excavator from italy?
Could have a tube over top of the screw to protect it and make it look like a cylinder rod??
|
Re: Powerful non-hydraulic Excavator from italy?
If you cover the threads how do you screw? I guess I just can't imagine it in my head.

Re: Powerful non-hydraulic Excavator from italy?
Here's another link for the model. If you look real close in the picture you can see the gear motor at the top of the cylinder. The cylinder down tube would cover an internal threaded cyl rod. The rod is fastened solid at the bottom so it can't turn. All we have to do is just figure out what thread there using

Re: Powerful non-hydraulic Excavator from italy?
Your on the right track, steamer. And it would leave a massive amount of room inside with not having the pump and valves everywhere. No oil all over everything if you develop a leak. It's very ingenious to say the lest.

Re: Powerful non-hydraulic Excavator from italy?
Or the tube holds the nut on the blind end of the "rod" and you spin the screw inside of it all

I am surprised that someone in Germany hasn't manufactured a variety of small screw drives already, with all of the rc construction interest there.
|
Re: Powerful non-hydraulic Excavator from italy?
With all of the manufacturors of construction equipment with hydraulics in Germany, I can see why there wouldn't be much talk about this model in Europe. I like the idea but still too much money for me to take a chance on something new.

Is it just me or does it look like thin material used in the boom and bucket?
