Equipped with the right chisel set, the IQIP Hydrohammer becomes a highly effective and powerful rock breaker, able to produce the high impact force necessary for breaking rock, cemented layers, concrete floors, and slabs.
If cutter dredging is no longer possible because the rock is too hard (average compressive strength greater than 40 MPa), or dredging is not justified economically in the case of relatively small volumes, a rock breaker can be an excellent solution. Where removal of hard rock by means of explosives is not permitted for safety or ecological reasons, the use of a Hydrohammer rock breaker may be the only solution.
The Hydrohammer can be used as a rock breaker both on land and underwater. For that purpose, our Hydrohammers are equipped with a special sleeve with an internal anvil (seated on spring cushioning) and a chisel that slides in the special sleeve. After being driven into the rock, the hammer and chisel are lifted and moved to the next spot. An important advantage of the Hydrohammer is the ability to deliver up-wards blows. Doing so while lifting the hammer at the same time strongly facilitates the retraction of jammed chisels.
