1700 Rock Breakers are a type of hydraulic breaker used in construction, mining, and demolition to break through hard surfaces such as rock, concrete, and asphalt. The 1700 designation refers to the weight class of the breaker, which typically ranges from 1,500 to 1,800 kilograms. These 1700 Rock Breakers are typically powered by a hydraulic system, which uses pressurized hydraulic fluid to generate the force necessary to break through the hard surface.
