I have added 2x4's and plywood (3/4") to the top to move a lathe and parts of a milling machine with good success. They are very sturdy, and the best part is that they are cheap enough so that if you break one, which is tough, you can toss it away and buy another for $10.

Iv'e done some other reading, and seems that cleaning and lubing the ball bearings (Texan: "ball bear-uns" ) help a lot. If the balls don't fall out.
