ABSTRACT:
This invention relates to a pan head (1) for supporting a device, preferably a film or television camera (2), having a stator (6) and a rotor (7) swiveling about a pitch axis (A) of the stator (6), whereby the rotor (7) supports the device (2). To permit determination of the torque between the rotor and stator with the device fitted on, and thus to facilitate e.g. the "balancing" of the fitted device in the zero position of the rotor (7), a torque sensor (31) is integrated into the pan head (1) for detecting the torque in several pitching positions of the rotor (7).
