Abstract (en)
[origin: EP1154075A2] The invention is a road scarifier for cutting road surfaces, comprising: a frame provided with a cutter, supported by tracks by means of hydraulic actuators suitable for modifying the position of said cutter with respect to the road surface; driving means to obtain the setting in motion of the machine and the rotation of said cutter; right and left sensors arranged at the sides of the machine and suitable for measuring the distance from the road surface; sensors to show the inclination of said machine with respect to the horizontal plane. Each one of said right (14) and left (13) sensors and said inclination sensor ( alpha ) sends signals to first data processing systems (16, 17, 19), said first data processing systems being suitable for comparing the values measured with those preset and for sending out difference signals ( delta S, delta D, delta alpha ) that are received by a data processing unit (20) capable of sending control signals (21, 22) to hydraulic actuators (7, 10) connected to the frame (2) of the machine, in such a way as to reduce to zero the difference signal sent out by said first data processing systems. <IMAGE>
