The design deals with the problem of levelling out positions of the sole pieces of the mechanical support during their moving. The problem is solved by the moving device being provided with levelling mechanisms, i.e. with a front levelling mechanism (28), which is arranged on the pillar side and with a rear levelling mechanism (29), which is arranged on the filling side. The moving device (1) is placed either inside the section of a mechanical support, between its sole pieces (13), or between two adjacent sections. The front levelling mechanism (28) comprises front inclined surfaces (21), which are mounted on guide bars (12), and front inclined props (22), which are fastened to the sole pieces (13). The rear levelling control (29) comprises rear incline surfaces (23), which are connected to guide bars (12) and rear inclined props (24), which are fastened to the sole pieces (13).<IMAGE>
