NPK’s GH series hydraulic hammers feature our direct acting gas-charged piston creating maximum impact per blow. Our long stroke piston design, coupled with our shock absorbing rubber mounts, reduces recoil to the operator while increasing the life of the carrier. NPK’s ABF feature allows the hammer to fire only when pressure is applied to the tool, increasing component life. These rugged hammers are capable of high production rates in all forms of concrete as well as both medium and hard rock. The simplicity of our hammer design is not limited to the main components. The standard bracket style makes servicing your NPK hammer simple. While lying horizontally, the hammer body can be removed without having to remove the top bracket.
