A straddle truck for containers has two upright lateral frames mounted on respective sets of wheels and held together by transverse beams fixedly connecting the tops of the columns at the front and rear ends of the frames. The columns are vertically extendable to increase the clearance under the transverse beams to more than the combined height of three standard containers, the transverse beams clearing two superimposed containers in the retracted condition of the columns. A lifting frame suspended from the tops of the columns carries standard couplings for engagement with the four top corners of a container. The truck permits containers to be stacked three high without the use of a separate crane, yet it can pass under bridge cranes and the like having a vertical clearance sufficient only for conventional straddle trucks.
