Komatsu V-Series breakers are designed for maximum productivity in any application, whilst lowering cost per ton. They are at home in any application, for demolition, mass excavation or secondary breaking.
The breakers fully modulate their impact force and frequency to match the application’s requirements, with no wasted energy and much higher operating efficiency. Greater positive impact on the material, on the pocket and the environment.
Like the H-series breaker, many features carry over to the V-series including automatic greasing, advanced blank firing protection, swivel hose couplings and a heavy-duty housing are standard. In addition, patented bushing protects the tool and retaining pins by absorbing any torque on the tool.
Depending on the application’s hardness, V-series breakers automatically select the optimal piston stroke length and speed. By adjusting to either hard material, with long and powerful strokes, or to softer material, with shorter, faster strokes, the highest production output is consistently achieved, with no waste of impact energy.
Integrated automatic lubrication as standard: Provides continuous greasing, extending the lifetime of the bushings and tool, protecting your investment.
Pressure regulator valve: Maintains a constant operating pressure, providing powerful impact strokes, whatever the conditions.
Fully suspended, silent: The fully suspended powercell reduces shock wave transmission, resulting in higher operator comfort and less noise.
Large diaphragm accumulator: Full power, day after day. Smoothens pressure spikes, protecting the carrier.
Swivel hose couplings: The hoses are connected on articulated couplings, allowing them to move freely, for less breakage risk and a longer lifetime.
Patented overflow protection: These breakers are protected from accidental flow adjustments thanks to a patented overflow protection system.
Energy recovery valve: More than 90% energy recovery, making them the most efficient breakers in their class!
Advanced blank firing protection as standard: Protect your investment! Piston movement is not interrupted, but impact is prevented by a hydraulic brake. Saves time and money.
Tool Protection System: Torque on the tool is absorbed by the TPS bushing, instead of the retaining pins. In combination with bronze bushing, this dramatically extends the tool’s lifetime.
The right tool for the job: Choice of various tools for each type of application. Standard: Moil point, pyramid, chisel or blunt tool Specials: Special tools are available for dust extraction, super abrasive applications or work in soft ground.
Fully variable automatic speed selection: Enabling the highest production in any application, these breakers can select exactly the right amount of power to break through the material, without wasting any energy.
