The invention discloses a hanging electrical control cabinet comprising an electrical control cabinet body, a hanging side plate, a hanging crossbeam, a hanging punch, a power supply pipeline connection port, a ventilation pipeline connection port, a hanging module, and fixing hooks. The hanging side plate is installed on the side of the electrical control cabinet body. The hanging crossbeam is horizontally fixed to the inner side of the hanging side plate. The hanging punch is installed on the surfaces of the hanging crossbeam and the hanging side plate. The power supply pipeline connection port is arranged on the surface of the hanging side plate. The ventilation pipeline connection port is arranged on the surface of the hanging side plate. The hanging module passes through the hanging punch to be installed on the hanging crossbeam by the fixing hook. The fixing hooks are installed on the four corners of the hanging module. By means of the above manner, the hanging electrical control cabinet is additionally provided with the hanging side plate, the hanging crossbeam, and the hanging punch in view of problem that the modules of a conventional electrical control cabinet cannot be moved and the conventional electrical control cabinet is poor in expansibility. The modules of the hanging electrical control cabinet can be moved and the hanging electrical control cabinet is improved in expansibility.
