An excavator with a rock hammer, also known as an excavator-mounted hydraulic hammer or breaker, is a heavy-duty construction equipment used for breaking and demolishing rock, concrete, and other hard materials. It combines the digging capabilities of an excavator with the power and impact force of a hydraulic rock hammer.
Here's how it generally works:
Excavator setup: The excavator is equipped with a hydraulic system capable of providing high pressure and flow rates to operate the rock hammer. The hammer attachment is typically connected to the excavator's boom or arm.
Positioning: The excavator operator positions the machine close to the area where the rock or concrete needs to be broken. The arm and boom of the excavator allow for precise placement of the rock hammer.
Attachment connection: The hydraulic hoses of the rock hammer are connected to the excavator's hydraulic system, usually at dedicated auxiliary hydraulic ports. This allows the excavator to control the hammer's operation.
Operation: The operator activates the hydraulic circuit for the rock hammer, sending pressurized hydraulic fluid to the hammer's piston or striking mechanism. The piston rapidly moves up and down, delivering high-impact blows to the material being broken.
Breaking process: As the rock hammer strikes the material, the impact energy fractures and breaks it apart. The operator controls the force and frequency of the blows by adjusting the hydraulic settings of the excavator.
Removal of debris: Once the material is broken, the excavator is used to clear away the debris and continue the excavation or demolition process.
Excavators with rock hammers are commonly used in construction, mining, quarrying, and demolition projects. They offer efficient and precise rock-breaking capabilities, reducing the need for manual labor and specialized equipment. However, it's important to have skilled operators who are trained in the safe and effective use of this equipment to ensure optimal results and minimize the risk of accidents.
