A friction motor is provided in a front cross beam (6), a rear cross beam (7) and a frame plate (8), and includes a flywheel (14) and a reduction gear e.g. pinion gear with a helical gearing, and belt drive. A transmission ratio of the friction motor ranges from 1:12 to 1:17. 10, 30, 45 and/or 90 degree-markings are attached on the flywheel. A tripod and/or an adapter (16) receives a camera. A friction gear drives a rotary plate. The dolly is dimensioned such that the dolly is carried by a person in a suitcase.
