After the tower crane 2 is installed, the hoist is used to rotate the boom 22 and the counterweight arm 23, and then the second telescopic member 241 and the third telescopic member 251 are rotated so that the second plug 242 can be inserted into the second socket 243 and the third plug 252 can be inserted into the third socket 253. And by driving the second telescopic member 241 and the third telescopic member 251, the angles of the boom 22 and the counterweight arm 23 are further adjusted. Finally, the first cable 26 and the second cable 260 are installed to further fix the boom 22 and the counterweight arm 23.
