ABSTRACT:
A control apparatus for a pavement breaker which includes a carriage, a lifting means for raising and lowering an impact arm which impact arm includes a tool for impacting a surface, mounted on one end and an oscillating member mounted on the other end. The control apparatus basically includes electrical apparatus for measuring the total weight being applied through the lifting means to the tool when it is in contact with the surface to be impacted and apparatus for limiting the amount of horizontal force that can be applied to the impact arm during the process of impacting the surface of the earth. A processor receives an electrical signal from the electrical apparatus which is applied to the lift control apparatus in a manner to stabilize the lifting force. A signal output is generated by the horizontal force limiting apparatus when a predetermined amount of horizontal force is received by the electrical device. The generated output signal is communicated to the lift control apparatus for removing the vertical force or weight from the tool to an extent necessary to remove the excessive horizontal force being applied to the impacting apparatus.
