Abstract
The present disclosure relates to a crane, preferably a crawler or truck crane, comprising a crane monitoring means for monitoring the operating condition of the crane, including a calculation unit and a control and display unit. In accordance with the present disclosure, there is additionally provided an operations planner with a separate monitor output, which includes a further calculation unit and which operates on the one hand as a device for planning the operation of the crane and on the other hand as a redundant crane monitoring unit in addition to the crane monitoring means.
Claims19
A system comprising:
- a crane;
- a sensor coupled in the crane and configured to detect an operating condition of the crane;
- a crane monitoring means incorporated in the crane, operatively coupled to the sensor, and configured for monitoring the operating condition of the crane, the crane monitoring means including a calculation unit and a first display unit;
- and
- an operations planner incorporated in the crane, operatively coupled to the sensor, configured for planning an operation of the crane and for redundantly monitoring the operating condition of the crane in dependence on the sensor, the operations planner including a computer and a second display unit.
A system, comprising:
- a crane;
- a sensor coupled in the crane and configured to detect an operating condition of the crane;
- a crane operating condition monitor incorporated in the crane, operatively coupled to the sensor and configured for monitoring the operating condition of the crane, the crane operating condition monitor including a calculation unit and a first display unit;
- and
- an operations planner incorporated in the crane, operatively coupled to the sensor, and configured to execute at least one program for planning an operation of the crane, the operations planner further configured to execute the at least one program for redundantly monitoring the operating condition of the crane in dependence on a value detected by the sensor, the operations planner including a computer and a second display unit;
- wherein the crane operating condition monitor and the operations planner are further configured to exchange data with each other.
A method for planning and monitoring operations of a crane, the method comprising:
- planning an operation of the crane via an operations planner comprising a computer and a first display unit disposed in the crane;
- monitoring an operating condition of the crane via a crane monitoring means comprising a calculation unit and a second display unit, also disposed in the crane;
- and
- redundantly monitoring the operating condition of the crane via the operations planner, wherein the first display unit can be switched from displaying crane planning operations to displaying the operating condition.
