Crane having a crane controller

A crane, in particular loading crane, comprising an arm system including several arms, wherein the arm system further includes:

• a crane column, rotatable about an axis of rotation, which is mounted pivotable over a structurally predefined crane column pivoting range and has one degree of freedom due to its pivotable mounting,
• a main arm, which is mounted on the crane column pivotable over a structurally predefined main arm pivoting range and has one degree of freedom due to its pivotable mounting,
• an articulated arm, which is mounted on the main arm pivotable over a structurally predefined articulated arm pivoting range and has one degree of freedom due to its pivotable mounting,
• at least one extension arm, which is mounted in the articulated arm displaceable over a structurally predefined extension range and has one degree of freedom due to its displaceable mounting,
• and wherein the crane has a crane controller which is configured, in a coordinate control operating mode, to carry out a coordinate control of the arm system,
• wherein the crane controller has a user interface, wherein the user interface has at least one function that can be chosen by a user, through which at least one of the degrees of freedom of the arm system is limitable or limited in the coordinate control operating mode.
