(1) The operating pressure of the hammer will vary with the amount of back pressure, input flow, and the hardness of the material. The operating pressure of the hammer will be higher against a harder material such as a steel plate. The operating pressure of the hammer will be lower during operation against a softer material such as rock or concrete.
(2) The relief valve just starts to open at this pressure.
(3) Refer to Special Publication, SEBU6250 for more information.Intended Use
A powerful percussion hammer fitted to an excavator and powered by an auxiliary hydraulic circuit for demolishing concrete or rocks. Hammers are used for jobs too large for hand held jackhammers or areas where blasting is not permitted due to safety or environmental issues.
