摘要 |
There is disclosed a telescopic mast (2) including two or more cylindric telescoping sections (4) with parallel walls (6), where the distal one of two adjacent telescoping sections (4) is narrower than the proximal one of the two adjacent telescoping sections (4), so that the distal telescoping section (4) can be moved into and out of the proximal telescoping section (4), respectively. In the interspace (8) between two adjacent telescoping sections (4) there is provided at least one device (10) interacting with an actuator (16) and pressing the adjacent walls (6) away from each other. Hereby play is eliminated or minimized. |
