A loading device for containers (C) comprises a pair of loading units (2), each having a telescopic column (4) supported on a bracket (3) so as to be swivelled about a common swivel axis (I). The telescopic column consists of a lower portion (9), an upper portion (11) and a column cylinder (17) moving the upper portion (11) with respect to the lower portion (9). Actuating cylinders (5) are connected to the lower portion (9) on both sides, and the upper portion (11) accommodates an extension arm (14) which can be swivelled about a swivel axis (III) parallel to the swivel axis (I) of the telescopic column. To expand the loading possibilities, the upper portion (11) carries a column head (12) which forms a slot-shaped swivel guide (18) with cam tracks (19) limiting the swivelling of the extension arm (14). The extension arm (14) has guide members (20) and is pivotally connected with a sliding piece (13) movably seated inside the upper portion (11) which opens towards the swivel guide (18), where a constriction (21) is provided between the cam tracks (19), so that the guide members (20) of the extension arm (14) aligned in a position stretched with respect to the telescopic column (4) simultaneously contact both cam tracks (19), and on the side of the upper portion the column cylinder (17) acts on the sliding piece (13) which can be moved upwards along a path limited by a stop.
