A method and apparatus for handling a wheel of large mass from a storage position to enable its mounting onto the hub of a vehicle, wherein the method includes placing a tire in a handling device having two ends which are of substantially equal length, the length being longer than the perimeter of the wheel, between two ends of the handling device, bringing together the ends of the handling device so as to imprison the wheel within the handling device, and hooking the ends of the handling device into a handling and lifting device.
A protection device for a vehicle cab having a floor and two vertical side walls, the device including an armor plate below and substantially parallel to the floor of the cab, and deformable compartmented caissons connected between the floor and the armor plate and under the side walls of the cab, each compartmented caisson having buckleable walls dimensioned to buckle upon shock impact to the exterior of the armor plate.
The invention relates to an armored door (5) for the crew compartment of a vehicle or fixed shelter, such door intended to block an opening (10) into the compartment and incorporating a structure (7) to the exterior of which at least one armor plate (12) is fastened.
The armor plate (12) is fixed at a distance from the structure (7) and is separate from said structure by first deformable intermediate means (14) able to absorb part of the energy of a shock, the armor plate (12) having, furthermore, dimensions that are greater than those of the structure (7), and second deformable intermediate means (15) positioned between the rim (R) of the armor plate (12) and a wall (8) of the compartment surrounding the opening (10).
The invention relates to a seat (1) for an armored vehicle, incorporating a back rest (2) integral with a wall or the roof (4) of the vehicle and a sitting part (3) mounted able to pivot with respect to the back rest (2) between a folded position in which it is substantially parallel to the back rest (2) and an unfolded position where it is held by a limit stop and is substantially perpendicular to the back rest (2).
This seat is characterized in that the sitting part (3) is connected to the back rest (2) by linking means (6, 8) ensuring, in the event of a predetermined load, the release of the limit stop (8) of the sitting part (3) and its pivoting beyond the unfolded position.
