because of a little thing known as the square cube law, (size and mass do not scale up equally) plus the type of crane that can lift 7+ tonnes and support that wieght is generally the type of thing constructed on site and anchored to the ground by concrete foundations and aren't running about the place.mb16 said:i have seen normal Steel I beams used in cranes that can support +7tonnes so why couldn't a leg/arm/etc in the carry 30 tones or so if it was properly made. Also im pretty sure a mech is alot more "practical/easier" to make than a gundam. For a mech once you have the legs done you basically fit a tank to the top and add guns.
also YOUR BEING SILLY so ha!
and again you're still comparing apples to oranges when both are equally implausible in the real world (especially since the gundam franchise as a whole has so many different timelines and continuities that you need a flow chart to come to grips with it, with different series governed by complately different fictional physics and technobabble)
plus putting legs on a tank is the worst thing you can do, as it raises its profile and centre of gravity, and makes the thing easier to see and hit, and to topple it over you only need to take out one of the legs
the only mecha/robot that is even remotely practical/plausible is the scopedog from armored trooper VOTOMS, and even then the series portrayed them as little more than a 3 meter high metal coffin with arms and legs
