Abstract

A stabilizer leg arrangement with a stabilizer leg (25), which is extensible by a hydraulic cylinder (27) into a supporting position in contact with the ground. A piston (32) divides the internal space of the hydraulic cylinder into first and second chambers (34, 35), wherein these chambers are configured to come into fluid communication with each other through a flow channel (41) in the hydraulic cylinder when the piston reaches an advanced end position and abuts against a stop surface. An electronic control device (72) 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 (V1) related to the hydraulic pressure in the first chamber (34). The invention also relates to a corresponding method and a mobile working machine comprising such a stabilizer leg arrangement.
