An operation apparatus for loading a crane is provided to display a pivot angle and the current torque together with a curve representing the maximum allowable torque with respect to the entire angle. In an operation apparatus for loading a crane, the direction of the crane is characterized by a radius section extending from an axial line(14) in the form of a bar(25). The operation apparatus for loading the crane includes a display screen capable of displaying a load and the torque applied by the crane with respect to the maximum allowable value. The direction of a surface defined by the crane with respect to a horizontal surface and the current torque are displayed together with a curve representing the maximum allowable torque with respect to the entire angle range.
