1. An airplane tractor having a gripping system for gripping a nose gear of an airplane, the airplane tractor comprising:
- a chassis;
wheel modules connected to the chassis, each of the wheel modules including at least one actuator for inducing a vertical movement of the wheel module in relation to the chassis;
a gripping platform for gripping the nose gear of the airplane, the gripping platform having freedom of movement such that the gripping platform is movable in a substantially pendular movement in relation to the chassis; and
an actuating means connecting the platform and the chassis, the actuating means including a damping means for damping the freedom of movement of the gripping platform in relation to the chassis.

Abstract
A plane tractor that grips a nose gear of a plane is disclosed, which includes: a chassis; wheel modules connected to the chassis, with each wheel module including at least one actuator for inducing a vertical movement of the wheel module in relation to the chassis; a gripping platform for gripping the nose gear of a plane, with the platform together with the chassis having freedom of movement substantially in circular translation; and a damping and actuating means connecting the platform and the chassis.

7. A method for gripping a nose gear of an airplane using an airplane tractor, the airplane tractor including a chassis;
- wheel modules connected to the chassis, each of the wheel modules including at least one actuator for inducing a vertical movement of the wheel module in relation to the chassis;
a gripping system for gripping the nose gear of the airplane, the gripping system including a gripping platform being moveable in a substantially pendular movement in relation to the chassis, the gripping platform going from a retracted position to a gripping position by way of an equilibrium position; and
a damping and actuating means connecting the gripping platform and the chassis, the method comprising;actuating the damping and actuating means to place the gripping platform in the retracted position; lowering the chassis; moving the airplane tractor so as to place the retracted gripping platform in contact with at least one wheel of the nose gear of the airplane; actuating the damping and actuating means to move the gripping platform from the retracted position toward the gripping position while adjusting the height of the chassis by controlling the actuators of at least two wheel modules so as to slide the gripping platform under the wheel; raising the chassis; and bringing the platform back to the equilibrium position. - View Dependent Claims (8, 9, 10, 11)
