Hello!
Check out my new pics of a large cable mining shovel:

I have been experimenting with using non-lego motors to drive this thing and
have had a lot of success at it. The hoist (to make the bucket go up and
down), wheels (for forward locomotion and steering), and swing (spin the top
part of the machine) are all powered by teams of 18 volt motors I purchased
at Radio Shack. The whole system is run with a battery from a residential
phone system. The radio shack motors are more powerful than lego motors, and
much cheaper.

Hi Ben, great shovel! I have a couple of questions though - I can’t tell from
the pics, does the bucket release door open? If so how? Also, have you found
that using the high power motors puts more stress on any bricks, or causes more
wear?

It stands 25 inches tall, almost 36 inches long with the bucket all the way
out. Gross vehicle weight is appx 40 lbs.
Stay tuned for video of the machine digging..

Cool, can’t wait for that!
Thanks!
