Abstract
A stabilizer leg arrangement with a stabilizer leg (), which is extensible by a hydraulic cylinder () into a supporting position in contact with the ground. A piston () divides the internal space of the hydraulic cylinder into first and second chambers (), wherein these chambers are configured to come into fluid communication with each other through a flow channel () in the hydraulic cylinder when the piston reaches an advanced end position and abuts against a stop surface. An electronic control device () is configured to establish information as to whether or not the stabilizer leg is in the supporting position while taking into account a measuring value (V) related to the hydraulic pressure in the first chamber (). The invention also relates to a corresponding method and a mobile working machine comprising such a stabilizer leg arrangement.
