Abstract

The invention concerns a lattice boom crane, which is composed of at least two individual lattice boom cranes (1, 11), which each comprise a luffing lattice boom (4, 14), whose luffing angle is adjustable by a luffing mechanism (5, 15). The lattice booms (4, 14) of the individual lattice boom cranes (1, 11) are connected with each other and oriented in parallel and adjacent to each other and the luffing mechanisms (5, 15) of the lattice boom cranes (1, 11) are synchronously operated, such that the rigidly-connected lattice booms (4, 14) are synchronously luffable.
