Abstract
The mobile working machine has a chassis (,) comprising at least four wheels (,) arranged in pair-wise associated with wheel axles (,) and connected to a frame (,) by interposed wheel springs (,) pre-tensionable by the effect of a load exerted on the frame. Two support legs (,) are also provided laterally one opposite the other on the sides of the frame, associated with one of the wheel axles (,), preferably the back axle, which have a foot-part (,) which can be extended downward and supported on the ground thereby lifting the chassis. At least one blocking mechanism is also provided to selectively release or block the spring path of one of the wheel springs (,). In order to ensure reliable and safe manipulation during blocking of the axle, the blocking mechanism (,) automatically moves in the blocking direction when the foot-part (,) is pulled out and automatically moves in the release direction when the foot-part (,) is retracted.
