Abstract
A crane is disclosed, with one or more moveable components. Manually-articulable controls (such as joysticks) are provided for controlling movement of the components. First, second, and third control circuits responsive to varied positions of the control are optionally connected to the control to provide first, second, and third sets of control signals each with differing responses to the control in a given position so as to move the components in a manner which mitigates instability or inaccuracy due to the physical acuity of the operator.
