A hydraulic hammer press has been used in the construction of a variety of building materials since its invention in 1883.
A hydraulic press is made from an electric motor which rotates an inclined disc to generate hydraulic power.
This disc is pushed into the ground by a hammer or other heavy tool, then a hydraulic press arm or hydraulic stone press is used to lift it.
The hammer or stone press then strikes a flat surface in the desired direction.
As the hammer or press pushes the disc down, the hammer moves back and forth against the disk to produce the desired force.
A mechanical engineer or industrial engineer can use a hydraulic hammer to make an automatic or manual hydraulic press, or a hydraulic stone hammer to turn a stone or concrete.
A lot of information about the history of the hydraulic hammer is available online.
But there are some questions that need to be answered to make sure the history is accurate.
The first article in this series deals with the history and current use of hydraulic press.
A second article, The History of the Hydraulic Hammer Press, looks at the history in a more detailed way.
The final article, A History of Hydraulic Stones, discusses the use of the stone hammer and hydraulic stone pressing.
