At the same time, the positioning column is hinged to the positioning column rotating seat, so that the composite plate is always in a horizontal state, thereby achieving the technical effect of precise positioning of the composite plate.

[0016] 3. Carry out construction layout in the installation area of ​​the composite board in advance. During the lifting of the composite board, first move the lifting frame to the installation area, turn on the laser locator at the bottom of the telescopic rear arm, fix the lifting frame according to the construction layout position, and make the lifting frame in a horizontal state. Then, the telescopic front arm captures the composite board fixing frame, start the winding machine, and the telescopic arm assembly drives the composite board fixing frame with the composite board to move down slowly to complete the lifting of the composite board. Compared with the traditional manual correction of the composite board by workers, this ensures the safety of workers while achieving the technical effect of fast and accurate lifting of the composite board.

[0017] 4. Pre-connect the hook lock of the crane tower to the hook seat of the composite plate fixing frame. When the telescopic arm assembly drives the composite plate fixing frame to lift the composite plate, the crane tower lifts another empty composite plate fixing frame equipped with a hook lock to the material area, and installs a new composite plate at the bottom of the empty composite plate fixing frame. During the lifting of the new composite plate, the lifting frame completes the installation of the previous composite plate and moves horizontally to the next installation area, realizing the alternating operation of a single crane tower, which greatly improves the installation efficiency of the composite plate.
