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

(You might have to wait a little while for the brickshelf gallery to be
moderated..)
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.
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..
Let me know what you all think!
Thanks,
Ben

| (...) 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? (...) (19 years ago, 23-Sep-05, to lugnet.technic, FTX)
