Hydraulic Breakers KSB/KFX for Excavator

… for excavators from 0.5-12t, benefits from a distinctive 'mono bloc' design, manufactured in a single piece and without any tie rods – a feature that makes the structure extremely durable and resistant to leverage during operation. The new KSB-series has a has a wide calibration range of the required oil flow for an easier setup. The tapered shape also ensures excellent visibility during operation, allowing the operator to work close to walls and other structures. 

• More power, less vibration and maintenance:Inertial nitrogen energy recovery gives more power and less vibration thanks to nitrogen chamber (no internal diaphragms), reducing maintenance costs.
• Long-lasting nitrogen: New sealing system and compound development has resulted in a 300% improvement in gas retention.
• Protected tubes: Tubes are completely protected through the casing and are suitable for all types of excavation, epecially in narrow spaces.
• Hydraulic system for blank firing: A regenerative oil circuit that avoids blank firing when the tool is not in contact with the rock.

… for excavators from 8-200t, has two adjusting valves as standard. First, a control valve on the cylinder of the hammer allows the operator to adjust the number of blows generated. A second valve allows the adjustment of the working pressure from 160 to 200 bar. Working in tunnels, and even underwater, is also possible by adding air tubes. The KFX breaker-series is available with a range of five different tools, suitable for penetrating a variety of surface structure.

• Regulation of the operating pressure: For KFX-breakers (KFX 20 to KFX 200), regulating the working pressure from 160 bar to 200 bar can be managed manually by valve adjustment.
• Blows adjustment: For KFX-breakers (KFX 20 to KFX 200), regulating the blow rate can be managed manually by adjusting a valve located on the side of the breaker.
• Hydraulic system for blank firing: A regenerative oil circuit that avoids blank firing when the tool is not in contact with the rock.
