The Brokk90 is one of the most versatile machines available on the market for demolition in confined spaces. The Brokk90 is all electric (fume free) making for a safe and clean work environment. We have different attachments for the Brokk90 including a 350lb. hammer, aswell as a crusher. The crusher is capable of crushing up to 12in. material (walls,staircases, etc.). The crusher makes for a much quieter work area. The Brokk90 is controlled by wireless remote control, letting the operater remain a safe distance away from the work area.
