  The largest land machine ever to move under its own power?  Heavens,

The largest earthmoving machines (and possibly the largest moving machines
on land) are the bucket wheel excavators (BWE) used in Germany. The biggest
one is the Orenstein & Koppel 292, which weighs in at 14,877 tons (short
tons- 2000 lb).

Holger Matthes modelled one of these things recently for the ISCC:
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=9483
If you look at the bottom of his gallery, there are pictures of the real thing.

In fact, a Bucyrus Erie 5872-WX cross-pit bucket excavator (the largest at
the time) worked in the same pit as the "Captain".

The Marion 6360, aka "the Captain", was the largest stripping shovel ever
made and weighed 14,000 tons. It had a 180 cu. yd. bucket with an average
270 ton load rating. It was scrapped in 1991.

It's operating weight was around 15,000 tons. Some other factoids:

It was the only shovel to have 2 doors on the bucket, each one weighed 15 tons
Each crawler shoe (of which there were 336) weighed aroun 3.25 tons
It was moved by 4 crawlers (each with 2 tracks), each 45ft long, 30ft wide,
16ft high, driven by 4 200hp AC motors
The 20 DC motors powering the hoist, crowd, rotate motion totalled 15,000hp

The largest single-bucket wielding machine was the Bucyrus-Erie 4250-W, aka
"Big Muskie". This machine, a walking dragline, weighed 13,500 tons. It had
a 220 cu. yd. bucket with a load rating of 320 tons. Big Muskie was parked
in 1991 and recently scrapped.

13,500 was it's design weight. It's final working weight (with
modifications) isn't known, but is estimated at 14,500 tons.

As another matter of interest, Marion was bought by Bucyrus-Erie sometime in
the last few years. At present, B-E doesn't produce any machines nearly as
large as the Big Muskie or The Captain.

Bucyrus International Inc. purchased Marion Power Shovel Company in 1997.
