Section steel platform tower crane base

The utility model relates to a section steel platform tower crane base in the field of construction equipment, which is designed to solve the technical problem of poor structural stability of the conventional similar tower crane bases. The design points of the tower crane base lie in that a reinforcing connecting plate is connected to the cross of an I-beam cross girder; supporting plates are connected to the top of a steel latticed column and U-beams, the U-beams are connected with the I-beam cross girder, and the steel latticed column is connected with the I-beam cross girder and the U-beams via a triangular connecting plate; the I-beam cross girder is connected with I-beams connected into a lattice shape, and a reinforcing U-beam is connected between the I-beam cross girder and the I-beams; and bearing plates are connected to upper and lower ends of the cross of the I-beams and the I-beam cross girder and are connected with a tower crane standard joint via nuts and screw rods.
