A conveyor made up of a plurality of groups of floor members (10). Each group includes two movable floor members (1, 2) and a fixed floor member (F). The movable floor member (1 and 2) are moved in unison, from a start position to an advanced position. This moves a load (L) on the floor because the area of the moving floor members (1 and 2) is twice the area of the fixed floor members (F). When the movable floor members (1 and 2) reach their advanced positions, they are stopped. Then, the first floor members (1) are returned to their start positions while the second movable floor members (2) are held stationary. The load (L) does not move rearwardly because it is held by the stationary floor members (2) and the fixed floor members (F). Next, the second movable floor members (2) are returned to their start positions while the first movable floor members are held stationary. Again, there is no movement of the load (L) because it is held by the stationary floor members (1) and the fixed floor members (F). When the second movable floor members (2) reach their start positions, the sequence is repeated.
