An apparatus for lifting containers to elevated positions for charging or discharging of a fluent material. The lifting apparatus includes a support member for the container. This support member may include an integral means for inverting the container. The support member is fastened to a carriage member which is movably guided interior of an elongated tubular column member. The carriage member is elevated or lowered by a lifting means which is mounted interior of the column member. The lifting means is connected to the carriage member by a pivoted link member. In the absence of tension on the lifting means, the link member will stop any uncontrolled lowering of the carriage member to a lowermost postion in the column member. The column member is attached to a base member. A second embodiment of the apparatus discloses additional attachment of the second end of the column member to a support structure. This second embodiment may be adapted for pivoting the apparatus about a vertical axis located within the column. The column member may include internal reinforcement means.
