Abstract

Improvements in the construction of machinery for public works, of the type that includes the turret, an arrow mounted oscillating on the turret, a work equipment that includes 2 deformable parallelograms whose major sides are equal and are simultaneously adjustable to acute and opposite angles by by means of an angular orientation mechanism, and by an adjustment device above the tool in relation to the ground, characterized in that the angular orientation mechanism of the greater sides of the parallelograms consists of two jacks, supporting said greater sides of the parallelogram the tool and being articulated on the adjustment device above the tool relative to the ground, said adjustment device being above the parallel movement type tool.
