The utility model relates to the technical field of voice broadcasters, and discloses a shoreside bridge crane equipment voice broadcaster easy to install, which comprises a box body, a voice broadcaster main body is fixedly installed in the box body, a loudspeaker is arranged above the box body, and connecting grooves are symmetrically arranged on the left side wall surface and the right side wall surface in the box body. According to the utility model, flowing airflow exists in the heat dissipation holes, the flowing airflow blows the collision balls in the heat dissipation holes when passing through the heat dissipation holes, and when the collision balls shake due to the influence of the flowing airflow, the collision balls continuously collide with the filter screen, so that the filter screen slightly shakes; meanwhile, due to the fact that the heat dissipation holes are the inverted-V-shaped grooves, the dust can be effectively prevented from entering the heat dissipation holes and being attached to the
