ABSTRACT:
A transporter vehicle comprises two lifting devices which carry respective jacks and which can be joined at their ends by cross bars to form a rectangular dolly with a central opening therein. The lifting devices each have front and rear wheels so that the dolly can be rolled on floor surfaces. In practice, the two are placed on opposite sides of a load seated on a floor in the opening between those devices, the jacks are placed under the load, the cross bars are assembled with the side frames, the load is jacked up on its opposite sides to be above the floor and the load may then be transported. The jacks may include linkages which cause the load to be lifted wholly vertically while not undergoing any horizontal translational movement.
