| 摘要 |
The invention relates to a mobile machine, especially a self-propelling concrete pump, comprising a chassis (10) and at least one support arm (20). Said support arm is located in a tubular or box-shaped telescopic section (18) which itself is located on the chassis (10), preferably in a horizontal position. The support arm (20) can move from a retracted transport position to at least one extended support position, and can be supported on the ground with a base part (26) at its free end. According to the invention, the support arm (30) has at least two arm parts (40, 42) which can pivot around an articulated axle (46), said axle being parallel to the vertical axis of the chassis (10). This provides a simple means of altering the support width across the support arm. |
