1. Vorrichtung zum Prüfen der Biegefestigkeit eines am Mastfuß (2) im Boden (3) verankerten, stehenden Mastes (1), bestehend aus einer Krafteinheit (4), mit welcher an einem Biegean­ griffspunkt (6) eine Biegekraft vorgegebener Größe in den Mast (1) mit Abstand oberhalb des Bodens (3) einleitbar und dadurch der Mast (1) mit einem Biegemoment belastbar ist, sowie aus einem dem Mast mit Abstand oberhalb des Biegeangriffspunkts (16) zugeordneten, ersten Wegsensor (17), dadurch gekennzeichnet, daß als Krafteinheit ein am als Zugpunkt ausgebildeten Biege­ angriffspunkt (6) angreifendes Zugmittel vorgesehen ist, wel­ ches sich an zwei Druckpunkten (10, 11), nämlich an einem un­ teren Druckpunkt (11) angrenzend an den Boden (3) und an einem oberen Druckpunkt (10) mit Abstand oberhalb des Biegeangriffs­ punkts (6) über je einen Kraftarm (8, 9) am Mast abstützt, und daß der erste Wegsensor (17) dem Mast (1) zum Anzeigen einer nach Entlastung des Zugmittels verbleibenden Mastauslenkung zugeordnet ist.1. Device for checking the bending strength of a standing mast ( 1 ) anchored to the mast base ( 2 ) in the floor ( 3 ), consisting of a force unit ( 4 ) with which a bending force of a predetermined magnitude in the mast is applied to a bending point ( 6 ) ( 1 ) can be introduced at a distance above the floor ( 3 ) and the mast ( 1 ) can thus be loaded with a bending moment, and from a first displacement sensor ( 17 ) assigned to the mast at a distance above the bending point ( 16 ), characterized in that as a force unit on the trained as a bending point of attack ( 6 ) attacking traction means is provided, wel ches at two pressure points ( 10 , 11 ), namely at a lower pressure point ( 11 ) adjacent to the bottom ( 3 ) and an upper pressure point ( 10 ) at a distance above the bending point ( 6 ) is supported by a force arm ( 8 , 9 ) on the mast, and that the first displacement sensor ( 17 ) shows the mast ( 1 ) to indicate a after relieving the tension is assigned to the remaining mast deflection. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der erste Wegsensor (17) dem Mast (1) mit Abstand oberhalb des oberen Druckpunktes (10) zugeordnet ist.2. Device according to claim 1, characterized in that the first displacement sensor ( 17 ) is associated with the mast ( 1 ) at a distance above the upper pressure point ( 10 ). 3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß dem Mastfuß (2) nahe dem Boden (3) ein zweiter Wegsensor (18) zugeordnet ist.3. Apparatus according to claim 1 or 2, characterized in that the mast foot ( 2 ) near the floor ( 3 ) is assigned a second displacement sensor ( 18 ).
