A drive roller for moving heavy structures includes a body having a load bearing surface and a roller engaging surface. Rollers supported by endless link chains are moveable about the roller engaging surface of the body. A shaft is rotatably mounted on the body. A worm wheel is non-rotatably secured to and rotatable with the shaft. A worm gear engages the worm wheel. Rotation of the worm gear imparts a rotary motion to the worm wheel thereby rotating the shaft. A sprocket is non-rotatably secured to and rotatable with the shaft. The sprocket engages the endless link chains. Rotation of the shaft results in the sprocket driving the endless link chains and rollers about the body.
