    The tower crane includes a boom and boom movable between a work configuration and a transport configuration. The mast has a first (2.1) and a second mast section. The boom has a first (4.1) and a second boom section. The first boom section (4.1) has an upper limit (4.11) and a lower limit (4.12) defining a height (H4.1) of the first boom section (4.1). The first mast section (2.1) is connected to the first boom section (4.1) in rotation about an articulation axis (Y24). The direction of arrow (X4) is offset with respect to the mast direction (Z2) parallel to the hinge axis (Y24). A distance between the hinge axis (Y24) and the lower limit (4.12) is greater than 75% of the height (H4.1) of the first boom section (4.1).
