CTHB Hydraulic Breaker – Box Series
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 rock breakers, 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.
“Efficiency, Safety, Convenience, and High Impact Power – All in One Premium Breaker.”

Key Features and Benefits
Key Features
- Improved side bolt: use material with high toughness.Can absorb energy and plastically deform without fracturing. Patent heat treatment process to increase the hardness of bolts. Reduce the bolts breaking rate down 45%.
- Noise reduction:enclosed bracket design and anti-impact damper mounted inside, highly reduce the noise when operating the breakers.
- Rubber: with rubber on the bucket, easier for pulgging in and out. Easy to assembly and change the chisel tool. Protect the edage of oil pipes, stay away from squzzing.
