The device comprises an arm (12) which is pivotable relative to the vehicle about a first axis (14) and carries a platform (8) in a manner such that it can pivot about a second axis (18). An actuator (44) imparts to the arm (12) an angular movement which brings the platform (8) from a lowered position to a raised position. Transmission means (30, 38, 16) enable the platform (8) to remain constantly parallel to its starting position during the pivoting movement of the arm (12). <MATH> |
