A tower crane comprises a lattice tower (1) composed of sections and comprising an upper jib (2). A lower tower (1) section is attached to a base (22) comprising supports (3) with feet (4). The supports (3) comprise a hydraulic levelling unit. The upper jib (2) is mounted on a turntable (16), fixed on the upper tower (1) section. The upper jib (2) is a telescopic jib and is provided with a pair of stiffening sprits (18). The tower (1) is composed of lattice sections and is provided with a cage module (15) for lifting and installing the next sections. The lattice tower (1) is provided with a unit of lattice middle sprits (12) with lower stays (11) in the form of couplers (8). The middle sprits (12) are connected from one side to working parts of hydraulic cylinders (14) installed in the crane foot (4) supports (3) and from the other side to the eyes (9) of the middle sprits (12) of the lattice tower (1).
