- a first adjusting mechanism connected to the tower at a distance from the bottom end of the tower, said first adjusting mechanism serving to raise the tower from an essentially horizontal transport position into an inclined position, and
- a second adjusting mechanism acting upon the tower in the region of the bottom end of the tower to shift the bottom end of the tower from a first location in relation to the vehicle when said tower is in the inclined position to a second location in relation to the vehicle to raise the tower from the inclined position into the vertical working position,
- the crane further including means for guiding the shifting movement of the lower end of the tower from the first location to the second location as it is raised.
