Abstract:
A cold cutting equipment of road surfaces comprising:side protection guards integral with skids that rest against the ground; and a cutting drum operably attached to a tiltable supporting structure, wherein the side protection guards include at least first and second curved slots with concave parts of the slots facing a central point, substantially coinciding with a center of rotation of the cutting drum, wherein a thrust pin is engaged in the first curved slot and a guide pin is engaged in the second curved slot, and wherein each thrust and guide pin is fixed to the supporting structure enabling the supporting structure to substantially tilt about the center of rotation of the cutting drum, allowing a substantial portion of the skids to rest against the ground at all times and to constantly maintain a chase cutting depth within operation tolerance limits that will not be subject to oscillation caused by a variation of position of the supporting structure due to uneven ground or irregular movements of the cutting equipment.
