The disclosure relates to a mounting for a payload (e.g. a TV/Video camera) comprising a platform (18) providing a mounting face for the payload, means (15, 19) to mount the platform for rotation about a horizontal axis for tilting of the platform to either side of a neutral position in which the platform is horizontal and spring (25) means to provide resistance to the said tilting movement in either direction from said neutral position to counterbalance the payload/platform in any position of tilt. The spring means comprise a torsion spring means and coupling means (21, 22, 24, 24) are provided interconnecting the platform and said spring means with a mechanical advantage which increases automatically with movement of the platform away from said neutral position to compensate for the increasing spring resistance to tilting generated by the torsion spring to counterbalance the camera/platform combination through its range of tilting.
