In accordance with an embodiment of the present invention there is provided a support construction for supporting a structure on a substantially horizontal plane such as a floor. The support construction includes a number of stationary supporting members, a number of supporting wheels, and a moving mechanism for moving the number of supporting wheels with respect to the stationary supporting members at least in a vertical direction so that selectively the structure is supported on the stationary supporting members or the supporting wheels.
1 . Support construction for supporting a structure on a substantially horizontal plane such as a floor, comprising:
a number of stationary supporting means, and
a number of supporting wheels,
and moving means for moving said number of supporting wheels with respect to said stationary supporting means at least in a vertical direction so that selectively the structure is supported on the stationary supporting means or the supporting wheels.
2 . Support construction as claimed in claim 1 , wherein said moving means comprise a first and second frame element being movable with respect to each other, the stationary supporting means being mounted on the first frame, and the second frame element bearing the supporting wheels.
3 . Support construction as claimed in claim 2 , wherein the first and second frame elements are movable with respect to each other in a horizontal direction, preferably by means of a bolt and nut assembly, and wherein an axle of each of said supporting wheels is supported in a vertical slot in said first frame and a slanting slot in said second frame.
