This machine in somewhat ideal conditions and swinging 90deg it can move a pile of dirt approximately 44" high in about 8-10hrs of steady digging. With damp sand that number would be higher.
There are no clutches, all 3 motors are: 100vdc PM motors individually driven by 4 quadrant regenerative drives.
The only clutch is the jaw clutch that engages from drag to propel motion.
Eventually I will build the brake bands so I can set the brakes when needed.
Thanks for the compliments.
