| Zusammenfassung: | The utility model discloses a base frame for a tower crane. The base frame for the tower crane comprises a whole beam and a half beam which are connected vertically and is characterized in that the whole beam and the half beam are respectively provided with a plurality of connection flat plates which are capable of being connected with standard joints of the tower crane. By means of the technical scheme, compared with the prior art, the whole beam and the half beam are respectively provided with the connection flat plates, and the connection flat plates are capable of replacing vertical short angle steel and connection sleeves and being directly connected with the standard joints. Through the connection method, the connection positions between the connection flat plates and the standard joints are uniform in stress, and good in stress effect, and therefore the service life of the tower crane is prolonged, and the safety factor of the tower crane is improved. |
