Method for controlling an articulated turntable ladder of a rescue vehicle

A method for controlling an articulated turntable ladder of a rescue vehicle, said ladder comprising a plurality of telescopically extendable ladder parts including a tip ladder part that is connected to one or more other ladder parts of the plurality of telescopically extendable ladder parts to be pivoted around a horizontal first pivot axis by means of a first pivoting drive, a cage being connected to a free end of the tip ladder part to be pivoted around a second pivot axis by means of a second pivoting drive, said ladder being pivotably mounted to a base part on top of the vehicle by means of a third pivoting drive to be lifted or lowered around a third pivot axis, said second pivot axis and said third pivot axis being parallel to said first pivot axis, the method comprising:

• controlling the first pivoting drive such that an absolute inclination angle of the tip ladder part is maintained constant during a lifting or lowering movement of the ladder around the third pivot axis;
• and
• controlling the second pivoting drive such that an absolute orientation of the cage is maintained constant during a lifting or lowering movement of the ladder around the third pivot axis;
• wherein the absolute inclination angle of the tip ladder part is selected from a set of predetermined absolute inclination angles upon a user input command.
