Hand-held Concrete Crusher
Hand-held concrete crusher is used for concrete breaking and can be operated by one person. Less vibration and impulsive noise along the structure would be generated by hand-held concrete crusher than jackhammer. The sound pressure level at 7m from the working site is less than 70dB(A).
