ABSTRACT:
A vehicle 1 comprises an upper mounting 2 which is a hollow beam pivotally attached via pivot means 4 to a lower mounting 3 which is also a hollow beam. A work platform 15 is fixed on to the upper mounting for translational movement with the mountings. Inner beams 5, 6, 10 and 11 are slidable within the outer beams 2 and 3 and have attached to each of their ends yokes, which in turn have attached at each of their ends legs 8 and 13. The legs have feet 9 and 14 and are telescopically extendible, so that the weight of the vehicle can be supported alternately on each set of legs i.e. on legs 8 or legs 13. By causing all the inner beams to slide in the outer beams simultaneously while the vehicle is supported on one set of legs and then transferring the weight to the other set of legs and causing the inner beams to slide in the opposite direction, the vehicle can "walk". The work platform can move forward continuously. By rotating the upper and lower mountings relative to each other the vehicle can be steered and caused to travel in any direction.
