Zusammenfassung:	The invention relates to a method and system for controlling the crane (22) of a working machine (10, 44) by using boom tip control, in which method the crane (22) comprises at least two booms (24, 26, 28) and a head (38) of the crane, which booms are connected to the working machine (10, 44) and each other in an articulated manner, and which booms are moved in relation to the working machine (10, 44) and to each other by means of actuators (32, 34, 36) controlled by a control system of the working machine (10, 44), and in which method direction and speed of motion of the head (38) of the crane, controlled by the driver applying controls (50, 52) in the working machine (10, 44), is implemented by applying speeds of the booms (24, 26, 28) of the crane (22). In the method the speeds of the booms (24, 26, 28) of the crane (22) are controlled automatically.
