CTHB81 Box type Hydraulic Rock Breaker
CTHB Box Hydraulic Breakers are used for breaking rocks, concrete, weathered stone, and other different hardness rocks. Since, it widely applies in the field of mining operations, building demolition, bridge and road dismantling, secondary crushing, pavement breaking, frozen ground breaking, high-rise building demolition, and so on.
Box type hydraulic breaker, which we also name silent type, are full-closed bracket designs. The strengthened bracket can keep the mainbody away from rocks’ direct impact. Inside brackets, we mount an anti-impact damper between the brackets and mainbody, which absorbs the impact and supports the mainbody.
With a changeable top head, CTHB box-type hydraulic breakers make it easier to change the head to match different excavators with similar oil flow and operating oil pressure.
Ultimate silence, silent demolition.
High penetration, low noise and environmentally friendly.
Noise reduction and ear protection, long-lasting and durable.

*This specification may be changed without notice for performance improvement.
*Customization available.
Significant noise reduction: The fully enclosed housing effectively blocks high-frequency impact noise, meeting environmental standards.
Reduced machine vibration: Internal cushioning pads absorb impact reaction forces, protecting the excavator’s boom and structural components.
Protection of core components: The enclosed housing prevents the ingress of dust and debris, extending the service life of the breaker.
