A lifting device (1, 14, 18, 28, 31, 36, 46, 50) has three booms (2, 19) of adjustable length, which in each case have a first end section (4, 20) and a second end section (5, 21) opposite the first end section (4, 20). While the first end sections (4, 20) of all booms (2, 19) are articulatedly connected to one another, the second end sections (5, 21) are articulatedly and rotatably mounted in respective bearings (7, 24, 29). The bearings (7, 24, 29) are thereby arranged at fixed positions relative to one another. Furthermore, in each boom (2, 19) at least the first end section (4, 20) can be rotated about the longitudinal axis of the boom (2, 19) with respect to the second end section (5, 21). In particular, the booms (2, 19) always form a tripod, which is characterized by a high stability. The lifting device (1, 14, 18, 28, 31, 36, 46, 50) is therefore suitable for lifting very heavy loads, wherein greater ranges can be achieved compared to known lifting devices. In addition, the lifting device (1, 14, 18, 28, 31, 36, 46, 50) can be pivoted further than known lifting devices.
