Abstract: A suspension assembly of industrial fans is provided. The suspension assembly of industrial fans includes a suspending main rod and a sub rod. A first adapter is pivotally disposed on a bottom end of the suspension main rod and provided with a plurality of first assembly holes. One end of the sub rod corresponding to the first adapter is pivotally connected with a second adapter which includes second assembly holes corresponding to the first assembly holes. A fan body is installed at the other end of the sub rod. According to environmental requirements and wind field coverage, directions and angles of air flows from the fan body can be changed by adjustment of relative positions of the second assembly holes of the second adapter to the first adapter. Therefore, good air circulation and ventilation in the environment is provided.
