Abstract
A braking device comprises first and second braking device respectively constrained to rotate with the brake case and with a brake shaft. The device comprises a braking piston, resilient device for displacing the piston axially towards a braking position, hydraulic device for displacing the piston axially in the opposite direction towards a brake-release position, and mechanical brake-release device for bringing the piston into its brake-release position and for holding it there. These mechanical brake-release device comprise at least two brake-release systems each comprising a bore having at least one substantially radial first segment, a screw displaceable in the bore, and displacement transfer device comprising at least one intermediate member suitable for transforming the radial displacement of the screw into axial displacement for pushing away the piston.
