Device for covering the guiding mechanism of a movable trolley moving preferably along a fixed trajectory. The said trolley 1 is supported by arms 2, 2' which are guided along the said trajectory, a fixed platform extending over the entire length of the said trajectory and being, during the movement of the trolley, under and spaced from the said arms 2, 2' and spaced beneath the trolley, and by the fact that flexible sealing elements 11, 11' made for example from rubber are fixed along the two sides of the trajectory of the trolley so that the portions of the sealing element which are permanently opposite the trolley 1 are forced apart from the said trolley 1 by the arms 2, 2' of the trolley whilst the remaining portions of the said sealing elements are in contact with the respective longitudinal lateral edges of the platform 12. <IMAGE>
