ABSTRACT:
The invention relates to a mobile working machine, particularly a mobile concrete pump, comprising a device for monitoring the stability thereof when in operation. The working machine comprises a chassis (10), which contains a supporting structure with two front and two rear support struts (20). The support struts can be extended out of a transporting position and into at least one supporting position and each can be supported on a surface (28) by a telescopic supporting jack or foot (26). The working machine additionally comprises a working boom (14), which can be extended out of a transporting position and into working positions that project beyond the chassis, which can rotate about a vertical axis that is fixed with regard to the chassis, and which is preferably provided in the form of a concrete distributing boom. Measuring devices for determining the respective supporting load are arranged in the area of the supporting foot and their output signals are sent to a stability monitoring device. According to the invention, at least one force sensor (32, 34) is arranged in each supporting jack and is connected in an electrical measuring circuit (36, 38) for outputting a supporting load dependent measurement signal. The monitoring device comprises an evaluation electronic unit (54) which, in predetermined sampling cycles, can be subjected to supporting load measured values and, for their comparison, can be subjected to at least one predetermined stability-determining threshold value.
