Mobile machine with laterally pivoted supporting struts

A mobile machine, having a multi-axle vehicle chassis (14) carrying the machine and at least one supporting strut (30, 32) which is pivotal about a pivot axis (26, 28) parallel to the vertical axis of the vehicle on the vehicle chassis (14) or a support frame (24) fixed to the vehicle chassis from an inoperative position in which said supporting strut is pivoted against a longitudinal side of the chassis (14) into a laterally pivoted supporting position, the free end of which supporting strut (30, 32) is adapted to be supported on the ground by means of an extendable foot portion (54), and comprising a locking mechanism (2, 44, 48, 50) which prevents the supporting strut (30, 32) from rotating about its pivot axis (26, 28) in its laterally pivoted and locked supporting position, wherein the supporting strut (30, 32), in its laterally pivoted supporting position, is vertically displaceable along said pivot axis between a locked position and a released position, wherein said supporting strut (30, 32) when in said locked position, engages with a locking mechanism, and wherein vertical displacement of said supporting strut to said released position disengages said strut from said locking mechanism, wherein the supporting strut (30, 32) is adapted to be limitedly pivotal about the pivot axis (26, 28) by means of a hydraulic motor (38), wherein the motor (38) comprises a braking or locking member which is adapted to be operated independently of the locking mechanisms, and wherein the motor (38) comprises a torque converter (40) which radially protrudes over its motor casing and which is non-rotatably connected with its free end to the supporting strut (30, 32) at a distance from the pivot axis.
