Patent abstract
A lifting framework for an industrial truck has an extendible mast guided on a guide mast by rollers. Means are provided for bracing the extendible mast with the guide mast so as to prevent the extendible mast from inclining in the lateral direction of the lifting framework relative to the guide mast. The bracing means are configured such that, when the extendible mast is located in the top end position, a vertical movement of the extendible mast relative to the guide mast is prevented in the region of each of the two columns. A hydraulic lifting cylinder and a stop for the top end position of the extendible mast are arranged here in the region of each column.
