Data's construction is more advanced than the T-800's, so this suggests that he could lift more weight. Not sure about the T-1000. It's liquid metal, so comparing it to Data is like comparing apples to oranges.
T-800 can lift alot more since he's got that extreme fully armored Metal and hydrolics.
T-800's can lift One Thousand Nine Hundred, Ninety Nine, Centillion of what The Planet Jupiter is. T-1000 is just liquid metal and never shown to shapeshift into anything near the superior metal the T-800 has.
