Abstract:
1. A device for braking the supporting booms of an earthmoving machine, said machine equipped with two or more supporting booms, interconnected by pivoting points, and one or more positioning cylinders capable of determining the relative angular position of said supporting booms, comprising: one or more braking systems applied to said supporting booms, capable of exerting a braking action on said supporting booms, thus reducing the reaction force of the said one or more positioning cylinders; said one or more braking systems comprise first devices to determine a braking torque relative to said pivoting points, said first devices comprise one or more disk brakes to determine a braking torque on said pivoting points; said one or more disk brakes comprising a rigid support shaped according to a rigid, forked extension part of a first supporting boom, relative to a connecting pivoting point with a second supporting boom, said rigid support being applied to one or more brake disks; and at least one brake caliper wound around the said one or more brake disks, applied to the said second supporting boom; and second devices for keeping said brake caliper in a fixed position relative to said second supporting boom and to allow a flotation of said brake caliper around said brake disks and integral with said second boom and comprise pivots fitted into their holes, drilled at the ends of said caliper, which allow the caliper to slide sideways.
