The cage platform (1) is supported at the end of a swing arm (2) by a U-shaped frame (3). A device (11) for pivoting and rotating the platform is located between the arm and the base (7) of the frame, and comprises two supports (13, 15) pivotable relative to each other, and a link (16) allowing rotation of the frame relative to the second support (15). The arms (8) of the frame have a length greater than the maximum diagonal distance between the two raised arms and the corner formed by the base of the platform and one of the platform length side walls. Platform rotation is carried out when the platform and frame are vertically oriented and pointing upwards from the pivoting and rotating device. |
