Abstract
Dämpfungsanordnung für das Hubgerüst eines Flurförderzeugs mit einem ersten Mast (10) und mindestens einem im ersten Mast (10) teleskopisch angeordneten zweiten Mast (30), wobei die Dämpfung beim Einfahren des zweiten Mastes (30) in den ersten Mast (10) wirksam wird, wobei an beiden Masten (10,30) horizontale Flächenabschnitte vorgesehen sind, die an Querverbindungselementen der Masten gebildet sind und die nahe übereinander liegen, wenn die Masten (10,30) in einer hinteren Endstellung ineinander gefahren sind, an einem ersten horizontalen Flächenabschnitt ein mindestens einteiliges Dämpfungselement (50) aus einem steifen Elastomer befestigt ist, das eine Auflageseite aufweist, die am zugehörigen ersten Flächenabschnitt anliegt und eine der Auflageseite gegenüberliegende zweite Seite aufweist, mit der der zweite horizontale Flächenabschnitt zusammenwirkt und die zweite Seite so geformt ist, daß die Größe der verformten Fläche bzw. des verformten Volumens des Dämpfungselements (50) mit zunehmenden Eingriff des zweiten horizontalen Flächenabschnitts größer wird. Damping arrangement for the mast of a truck with a first mast (10) and at least one in the first mast (10) telescopically arranged second mast (30), wherein the damping during retraction of the second mast (30) in the first mast (10) is effective , wherein on both masts (10,30) horizontal surface portions are provided, which are formed on cross-connecting elements of the masts and which are close to each other when the masts (10,30) are driven into each other in a rear end position, on a first horizontal surface portion at least one piece damping element (50) of rigid elastomer having a support face abutting the associated first surface portion and having a second side opposite the support side, with which the second horizontal surface portion cooperates and the second side is shaped such that the Size of the deformed surface or the deformed volume of the damping elements (50) becomes larger with increasing engagement of the second horizontal surface portion.
