Loading device for containers or similar

A loading device for containers comprising a pair of loading units to be mounted on an undercarriage, which each have a telescopic column supported on a bracket so as to be swivelled about a common swivel axis extending in the longitudinal center of the undercarriage, which telescopic column consists of a lower portion pivotally mounted on the bracket, an upper portion movably guided in the lower portion, and a column cylinder moving the upper portion with respect to the lower portion, where actuating cylinders are connected to the lower portion on both sides, and the upper portion accommodates an extension arm which can be swivelled to both sides about a swivel axis parallel to the swivel axis of the telescopic column and has an abutment for connection of a load lifting means, characterized in that the upper portion carries a column head which forms a slot-shaped swivel guide with cam tracks limiting the swivelling of the extension arm, that the extension arm has guide members associated with the cam tracks and is pivotally connected with a sliding piece movably seated inside the upper portion which has an open end facing the swivel guide of the column head, where in the vicinity of the open end a constriction is provided between the cam tracks so that the guide members of the extension arm aligned in a position stretched with respect to the telescopic column simultaneously contact both cam tracks, and that on the side of the upper portion the column cylinder acts on the sliding piece which can be moved upwards along a path limited by a stop.
