Contents First Page Previous Page Next Page Previous View Balancing the head 12 Balancing the Vision 250 head achieves two objectives. Firstly, when a head is correctly balanced the operator will need a minimum amount of even effort to move the head. Secondly, once balanced, the head and its payload can be set to any tilt position and the head will maintain this position with “hands off”. 13 The graph (Fig 2.
