A mobile gantry for transporting heavy loads includes first, second, and third booms which are supported on the ground by respective wheel sets. The booms are spaced from one another so to present a generally triangular configuration when viewed from above. First, second, and third lift legs telescope to extend and retract the booms, and the lift legs are interconnected to one another and can raise and lower a load. The load can be maintained level by individually adjusting the length of each boom by extending and retracting the lift legs. A pivot axle, attached to each one of the wheel sets, allows each of the wheel sets to pivot about an axis that is at least generally parallel to the ground, thus maintaining a uniform load while the mobile gantry encounters changes in slope or other surface irregularities.
