A mechanical jackhammer pounds repetitively at a pile of rocks on a construction site. The jackhammer's metallic arm extends and retracts methodically, breaking up the rocks into smaller pieces. The machine's metallic grey and black exterior contrasts against the light brown earth and light blue sky in the background. The camera angle is low, highlighting the machine's strength as it breaks down the natural stone. Use this video for projects needing a symbol for construction, building, power, and force.
