    Concrete Removal

Handheld or excavator mounted concrete breaker is a traditional mechanical equipment for concrete breaking and removal. Using such equipment will generate loud noise, with sound power levels generally range from 108 dB(A) to 122 dB(A). Nowadays, a number of commercially available quieter equipment or methods for concrete breaking or removal could be less noisy or could reduce the noise propagation. These include high pressure water jet system, handheld concrete crusher, medium duty breaker, blade saw, wire saw and noise enclosure.

Hydraulic Crusher for Concrete Breaking

Use of hydraulic concrete crusher is much quieter than using hydraulic breaker in demolition projects. The operation principle of hydraulic breaker is by percussive striking actions of its chisels, so that much more noise would be generated as compared with hydraulic crusher.
