Why haven't you tried "digging" for the truth on this matter?
Just for this machine to exist requires the CAREFUL handling of 45,500 tons of steel, electronics and other equipment. Every time this machine moves - empty - it must use some miraculous or alien anti-gravity device just to keep from rumbling the entire mass (45,500 tons) into the world's largest heap of scrap steel?. ???
Remove the trenching bucket/wheel and add a simple crane type sling and it can move your stones easily and as carefully as the operator was told to be.
You have to be a really hardcore alien enthusiast (or nephilim, or whatever) to try and stick to your original statement. You ought to sign up for Internet service and just google your theories around.
In 1991, the entire and intact Cape Hatteras Lighthouse was moved to another location 1/2 mile away. The lighthouse weighs 4,830 tons - far, far more than the Baalbek stones you described - all together! See the first picture below.
Sorry, maybe I'm being too harsh, but c'mon! Just one Howie Long GMC commercial moves payloads of similar size to those "impossible to move stones."
The last pic is a contemporary depiction of Egyptians moving an 800 ton colossus.
