The DXR 140 is the smallest and lightest addition to Husqvarna’s new range of remote-controlled demolition robots. Despite its compact design, it is a powerful partner for demolition work in cramped spaces where the substrate requires a lightweight machine. The DXR 140 weighs only 2116 lbs. and has a 20-hp output. Its arm can rotate 360 degrees, reducing the need to move the machine, and has individually controlled outriggers that can pass through doorways and even climb stairs. Husqvarna. 800-288-5040.
