An anchor frame assembly of a tower crane is provided to improve the installing performance of the anchor frame assembly and to increase compatibility of the anchor frame assembly by selecting the extension frame with proper length even if the standard of the tower crane section is different. An anchor frame assembly of a tower crane is composed of four corner frames(10,20,30,40) placed at the corner parts of the tower crane section; extension frames(50,60,70,80) detachably combined between the corner frames; and fixing units for fixing the anchor frame assembly at the tower mast of the tower crane section. One end of the corner frames is combined to be at right angles, and the other end of the corner frames contains a pair of frame members formed with plural first combining holes. Second combining holes are formed at the extension frame to correspond to the first combining holes. A combining unit is combined through the first and second combining holes. |
