A load-changer for vehicles includes a rotatable cog-wheel (12) that is mounted on the edge of a load-carrier (2) included in the vehicle, and arranged to engage a cog-track on the under side of the load object in question, means being arranged to dampen the tendency of the load object to swing around the cog-wheel in connection with that the centre of gravity of the load object passes the cog-wheel. This damping means includes at least one arm, swingably mounted on the load-carrier, to which arm a spring or piston-cylinder mechanism (19) is connected, that, in connection with the loading of the load object onto the load-carrier (2), keeps the arm inclined upwards from the area of the cog-wheel. By this fact the arm can be brought into engagement with a guide extending along the load object, said mechanism initially counteracting the weight of the load object after that the centre of gravity of the load object has passed the cog-wheel, and then allowing the arm to be successively swung down, and thereby also the load object, into a plane essentially parallel to the load carrier. |
