The invention relates to a supporting bracket (38) of a supporting construction for mobile machine tools, especially for concrete pumps. The supporting bracket (38) is multi-telescopic and comprises a carriage (38) which is pivotably arranged on the chassis (10), and a telescopic part consisting of a plurality of telescopic segments (40', 40'', 40''') which are guided inside each other, engage in the carriage, and are mobile in relation thereto. The aim of the invention is to provide a narrow support using simple means. To this end, the carriage (38) and at least some of the telescopic segments (40'', 40''') have coupling points (50', 50'', 50''') on which the segments can be coupled in pairs in such a way as to produce a fixed connection when the segments are retracted in relation to each other.
