The 3,527-pound Brokk 170 remote-controlled demolition machine offers 15 percent more power than its predecessor, the Brokk 160. In addition, the B170 is compact and flexible — able to fit through standard doorways. The SmartPower electrical system withstands extreme day-to-day demolition forces. It also allows operation on a poor power supply while protecting the machine from harmful faulty power. SmartDesign features added protections and serviceability features that extend machine life and improve ease of maintenance. SmartRemote consists of an ergonomic remote-control box designed to minimize operator strain and make machine operation simple without the need to look down at the display. It is compatible with B160 attachments, including hydraulic breakers, concrete crushers, rock drills and more. 800-621-7856; www.brokk.com
