Abstract
A crane controller for a crane, in particular a cargo crane, has a first operating mode, in which the crane can be user-operated by control commands from an operator, and a second operating mode that can be activated by the operator. In the second operating mode, the crane geometry can be changed by the crane controller in a pre-defined sequence of movements. The crane controller has a menu-drive user interface, and the interface has a function which can be selected by the operator and by which the crane controller switches from the first to the second operating mode.
Claims29
A crane controller for a crane, comprising:
- a menu-driven user interface, the menu-driven user interface having a function to be selected by a user so as to switch the crane controller from a first operating mode into a second operating mode;
- wherein, in the first operating mode, the crane is freely operable by the user by control commands, and in the second operating mode activated by the user, the crane geometry is changeable in a predetermined sequence of movements by the crane controller;
- and
- wherein the second operating mode selectively (i) moves the crane in a predetermined manner from a parking position into a working position, and (ii) moves the crane in a predetermined manner from a predetermined working position into the parking position.
A crane controller for a crane, comprising:
- a menu-driven user interface, the menu-driven user interface having a function to be selected by the user so as to switch the crane controller from a first operating mode into a second operating mode;
- wherein, in the first operating mode, the crane is freely operable by a user by control commands and, in the second operating mode activated by the user, the crane geometry is changeable in a predetermined sequence of movements by the crane controller;
- wherein the crane controller outputs a safety query to be confirmed by the user at a predetermined point in the predetermined sequence of movements;
- and
- wherein at the predetermined point the crane controller pauses the predetermined sequence of movements of the crane geometry.
A crane controller for a crane, comprising:
- a menu-driven user interface, the menu-driven user interface having a function to be selected by a user so as to switch the crane controller from a first operating mode into a second operating mode;
- wherein, in the first operating mode, the crane is freely operable by the user by control commands and, in the second operating mode activated by the user, the crane geometry is changeable in a predetermined sequence of movements by the crane controller;
- and
- wherein, in the predetermined sequence of movements of the crane geometry, the crane controller monitors the stability of the crane or a vehicle on which the crane is disposed.
