determining a current tipping moment of the mobile crane, the current tipping moment comprising a moment about a tipping line of the mobile crane;
predicting an effect of the user input on the current tipping moment of the mobile crane; and
when the predicted effect of the user input is to increase the current tipping moment of the mobile crane past a predetermined amount, altering a response to the user input;
designating a first range of the eff ct of the user input as a safe ad a second range of the effect of the user input as a warning range; and
causing a user display, wherein the user display comprises at least one display element corresponding to one or more mobile crane characteristics affected by user inputs. each display element comprising a first portion designating a safe zone of the corresponding one or more mobile crane characteristics and a second portion designating a warning zone of the corresponding one or more mobile crane characteristics, to display the first portion and the second portion in dependence on a relation between the first range of the effect relative and the second range of the effect.
