Supporting construction

A supporting construction (10) for a work machine comprising a mast, a supporting leg box (12) which is open to a front side (16), and a supporting leg (20) slidingly movable in the supporting leg box (12) in a longitudinal direction (22) between a fully retracted position and a position in which it is fully extended from the supporting leg box (12) by a maximum extension length (A),

• wherein the supporting leg box (12) comprises a first load introduction device (30) in an area of its open front side (16), and a single second load introduction device (32) in the form of a substantially U-shaped bracket which is open in a direction facing the supporting leg (20), said single second load introduction device (32) having at least one supporting surface (34) arranged within the supporting leg box at a given distance (D) from the front side (16), and
• wherein the supporting leg (20) comprises a reinforcing element (36) extending along a length (L) of the supporting leg (20) and which rests on the at least one supporting surface (34) of the single second load introduction device (32).
