Abstract: A mechanical ejector device includes a sliding piston, a transverse lever articulated to a first fixed axis and to a first mobile axis coupled axially to the piston and including a second mobile axis, a first link articulated to a second fixed axis and including third and fourth mobile axes, a transverse actuator rod articulated to the third mobile axis to displace the latter in a single displacement direction and a second link articulated to the second mobile axis and to the fourth mobile axis. The fixed and mobile axes are parallel. The first link and the second link form a deformable assembly having an intermediate configuration in which the piston is in its service position.

Abstract: A device for lifting, steerably moving and putting down a load includes a removable dolly which cooperates with an anchor plate fixed to the load. The removable dolly includes a chassis provided at its front part with a lifting and abutment system which cooperates with a complementary system on the anchor plate, the chassis being lockable to this plate. A steering system embodies two wheels mounted individually on the chassis and a set of links which hold the wheels parallel at all times. An orientable maneuvering bar is pivoted to the chassis and to the set of links. A locking arrangement is provided for selectively locking the maneuvering bar relative to the chassis. A device of this kind can be used to move and to position equipment to be slung underneath an aircraft.

Abstract: The invention relates to a suspension device for linking an item of on-board equipment item to the structure of a vehicle, such as a rotary wing aircraft.Advantageously, it comprises first (5) and second (6) elements shaped at least approximately as plates and capable of being fixed respectively to said structure (3) and to said equipment item (2), and suspension means (7) including damping members (14) linked respectively to the first and second elements and capable of acting along the three roll, pitch and yaw reference axes of said aircraft to absorb the linear displacements along said axes, and elastic suspension members (15) linked respectively to the first and second elements and capable of acting around the three reference axes to absorb the angular displacements.
