Abstract
The invention relates to a method in a system using pressurized medium for employing and controlling a hoisting boom assembly particularly in combination with a working machine, the system comprising at least two cylinder-piston mechanisms (1, 2) using pressurized medium, a pressure unit (P) for pressurizing the medium, and a control unit (V) comprising two operating valves (4, 5) and using said cylinder-piston mechanisms (1, 2) by leading pressurized medium to their respective pressure chambers to be filled at a time and, in a corresponding manner, by removing pressurized medium from their respective pressure chambers to be emptied at a time. The method is applied particularly during simultaneous use of the cylinder-piston mechanisms (1, 2) by connecting the cylinder-piston mechanisms (1, 2) to operate in a series so that pressurized medium is conveyed from the pressure chamber of one cylinder-piston mechanism (1 or 2) to be emptied to the pressure chamber of the other cylinder-piston mechanism (2 or 1) to be filled up. The pressurized medium is returned to the control unit (V) from the pressure chamber of the other cylinder-piston mechanism (2 or 1) to be emptied.
