Mobile crane operation control

Abstract

- 1 - Abstract A method of, and corresponding system for, controlling an operation of a mobile crane, the operation comprising a user input, the user input comprising a command to change a configuration of the mobile crane, the method comprising the steps of: determining a current tipping moment of the mobile crane, the tipping 5 moment comprising a moment about a tipping line of the mobile crane; predicting an effect of the user input on the tipping moment of the mobile crane; and if the predicted effect of the user input is to increase the tipping moment of the mobile crane past a predetermined amount, altering a response to the user input. A further aspect relates to a user interface for displaying to a user effects of the user input on 10 the tipping moment of the mobile crane, the user interface displaying a safe range of effects of a user input and the non-safe range of effects of a user input, which may cause tipping of the mobile crane.
