In addition, the lifting devices such as the electric hoist and the like are integrated on the standard section of the tower crane, so that the safety of the tower crane is not guaranteed.

The lower cross support beam 2 is lifted up together with the tower crane 1 until the lower cross support beam 2 moves vertically from A-A to B-B, and then the first turning bracket 21 and the turnover embedment bracket 7 of the lower cross support beam 2 are fixed at the B-B position by using the wedge blocks 8.

S4, then, taking away the wedge block 8 between the second turnover bracket 31 and the turnover embedded bracket 7 at the C-C position of the upper cross support beam 3, lifting the upper cross support beam 3 at the C-C position to the E-E position by using the movable truss crane 6 which is integrated below the bottom beam 432 of the integral lifting steel platform 4 and can move unidirectionally, and fixing the second turnover bracket 31 and the turnover embedded bracket 7 of the upper cross support beam 3 at the E-E position by using the wedge block 8. When lifting the upper cross support beam 3, the tower crane 1 transfers a large part of vertical load and a small part of horizontal load by means of the lower cross support beam 2 and a large part of horizontal load by means of the adjustable horizontal support system 5.
