<p>A gearbox (35) has a first rotative component (70) and a second rotative component (60), the gearbox having a rotary input (40) and a rotary output (50), a first brake (100) for braking the first rotative component of the gearbox against rotation thereof, and a second brake (55) for braking the second rotative component of the gearbox against rotation thereof. The rotary input (40) drives the rotary output (50) if the first brake (100) brakes the first rotative component of the gearbox and the rotary output drives the first rotative component (70) of the gearbox (35) if the second brake (55) brakes the second rotative component (60) of the gearbox.</p> |
