Abstract
A drive train apparatus (1) adapted for driving a pan and tilt head, which in use is intended to support a payload (for example a video camera), the apparatus includes respective successive drive elements (2, 3, 4) so coupled as to communicate a rotational movement applied at one end of the apparatus (1) from an output of a rotational input device (8) to a rotational output (16) disposed at the other end of the apparatus (1), in a manner whereby the rotational velocity of the rotational movement is reduced across the drive elements (2, 3, 4) thereby converting the torque applied to the input of each drive element (2, 3, 4) into an increased torque at the output of each drive element (2, 3, 4); a first stage one of the drive elements including a belt drive.
