Wimmer hydraulic breakers are designed for all types of carriers between 1 and 100 tons. The automatic anti-idling device significantly increases the service life of the wearing parts. The automatic pressure regulator also ensures constant performance by being independent of the oil flow. The percussion mechanism of Wimmer hydraulic breakers is floating in a solidly damped and sound- and vibration-insulated housing. This protects the excavator boom and hammer housing from cracks and guarantees a low noise level.
