A load carrier includes a load changing frame that has first and second end portions. The load changing frame has two longitudinal frame beams, two transverse frame beams arranged at the end portions of the load changing frame, and a first, upwardly tapering lifting stand. The second end portion of the load changing frame includes a second lifting stand, which is shaped and arranged in accordance with the first lifting stand. The transverse frame beams are elongated to extend outward from the longitudinal frame beams for mounting of supports facing the support surface. A plurality of such load carriers are adapted to be stacked on top of each other, wherein each overlying load carrier with its lifting stands is adapted to straddle the lifting stands of the underlying load carrier vertically from above, wherein the length of the stack corresponds to the length of the load carrier.
