Hello everyone
As promised, there is now a video of the new status. As already described, the excavator has received the following changes:
- Working pressure 60bar optionally 70bar
- One hydraulic pump (IPZ2HR7) instead of 3 pumps
- A new valve block (prototype from Schwab Präzision GmbH)
- New lines and connections
The drive now has two brushless motors instead of brushed motors and an adapted gearbox for a higher speed.
I have to optimize the drive a bit again, I'm not completely satisfied with that. I am now very satisfied with the hydraulics. Really a lot of strength and still potential for more. I also really like the controllability. The valves can be controlled very sensitively and have correspondingly large cross-sections.
Have fun watching.
Greetings Andreas
