The barrel (10) is held (9,12) on an oscillating support (6), with a flexible pulling device (14) fixed to the holder. This is tensioned or released (18) to operate the holding and to enable the barrel to pivot through a right angle, moving from vertical to horizontal or vice versa. The device is mounted on a lifting trolley (3), with a static support (1). This vertical support may be fixed to the trolley vertical lifting frame (2). This may carry the oscillating support, which pivots through a right angle and has static (9) and sliding (12) jaws, clamping the barrel top rim (11). The flexible device may be a belt fixed to the sliding jaw at one end and the other to a winch (18).
