Gear box (1) comprising a gearbox body (2) defining a cavity (3) and, housed inside the cavity (3), an output shaft, and a braking device mounted on a rotating shaft (9), this braking device comprising two activatable brakes (61, 62), two stops (71, 72) mechanically coupled to one another and surrounding the brakes (61, 62), and a control member (8) for moving the brakes (61, 62), common to the two brakes (61, 62), and mounted to move between an inactive braking position and an active braking position, at least one of the stops (71, 72) forming an end-of-travel stop limiting the movement of the brakes (61, 62) in the active braking position of the control member (8). The shaft (9) equipped with the braking device is formed from two coaxial shaft sections (91, 92), mounted to freely rotate in relation to one another, and each equipped with one of the brakes (61, 62) of the braking device, the brakes (61, 62) are cone brakes and the stops (71, 72) form an assembly mounted to be able to move axially along the shaft (9), this assembly being separated in rotation from the shaft (9) or at least one of the sections of the shaft (9).
