Hydraulic breakers also known as hydraulic rock breakers, hydraulic rock drills or hydraulic jackhammers are hand operated tools for demolishing concrete structures or rocks. These breakers are powered by a low pressure hydraulic power source, such as pump (petrol/electric/diesel) or machinery (sometimes requires a flow control valve depending on machinery pressure and flow rate). Hydraulic breakers can be used with long hose sets keeping the breaker a long distance from the pump or power source. With the right power source/pump the tool can be operated for longer periods of time than self contained drivers or breakers (such as petrol/diesel), they can also be more powerful and weigh less than these units.
Alternate terminology: Hydraulic Jack Hammer, Hand Operated Hydraulic Breaker, Hand Held Hydraulic Breaker.
