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

(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

40 LBS! Dag that is a heavy one. It definately looks real. I have never
seen tracks like that, but then again TLC does not make tracks that could
hold that much weight without ripping apart, unless you wanted to spend a
fortune. What percentage of its weight in sand/dirt can it lift? I can
understand if you don’t want to get your parts dirty, but you are obviously
not a purist (Non-purists unite!) which is not a bad thing. The bucket is the
best part. I like how the platform is populated with several minifigs. If I
was a Lego minifig, I would want to climb up on that platform and watch too.
Great job!

P.S. I’ll put sand in my MOCs if you put sand in the bucket of your MOC!

Hello Nathan, so I do want to spend a fortune on the tracks.. I just need to
get my hands on one! Did you see the (incredible) “PARV”:
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1396024
I would really like to build some tracks like that machine has, when I get a
chance to save up some money and buy the parts.
I’m glad you like the minifig decks - My motto is “make it work good, make it
look good”.
As for the lifting capacity, so far I have only used the machine to dig legos.
I live in an apartment and do not have access to any sand. However the machine
can bite a heaping bucket full of legos out of a pile.. the bucket is about 4
inches to a side, so thats appx 64 cubic inches, but probably not more than a
pound or 1/2 pound.
I’ve just posted a video of the machine digging (again you might have to wait
for it to be moderated..):

This is an older video, before installation of the radio shack motors. These
days, the hoist (bucket up and down) performance is much better, it is way
faster and stronger.
Thanks for your comments Nathan!
