Equipped with a chisel set, the Hydrohammer® becomes a highly effective and powerful rock breaker. It is able to produce the high impact force necessary for breaking rock, cemented layers, concrete floors and slabs. Impact on environment or sea life is minimal compared to drilling and blasting.

Chisel with housing The Hydrohammer® can be used as a rock breaker both on land and underwater. It is fitted with a special sleeve that features an internal anvil and a chisel. After being driven into the rock, the hammer and chisel are lifted and moved to the next spot. Delivering upward blows and lifting the hammer at the same time strongly facilitates the retraction of jammed chisels. The System To withstand heavy resistance, the Hydrohammer® must be properly guided in a leader-guide profile. This operating criterion secures the central alignment of the chisel and hammer for optimum energy transfer between ram/anvil and chisel. The position of this leader profile should be fixed during breaking and extracting.

Operating Methods Different types of handling equipment can be used to lift and position the rock breaker and leader profile, including a piling rig, excavator or backhoe, or a cutter dredger. The choice depends predominantly on the equipment available for/on the project, and on water depth.

Rock Hardness 

To date, rocks with a hardness up to 180 MPa have been successfully broken using an S-70 Hydrohammer® to punch vertical holes in a relatively level surface.
