Abstract
A screwing device on a cantilever arm of a construction vehicle for screwing foundation installations into the ground has a suspension, a screw head, and an actuator. The actuator can be pivoted about two axes extending parallel to one another and transversely with respect to the longitudinal axis of the screw head. The articulation point on the screw head follows the motion of the pivoting lever on the longitudinal axis due to a migration of the articulation point from the longitudinal axis of the screw head occurring due to pivoting of the pivoting lever about the axes while screwing the foundation installation into the ground. The axes extend transverse to the longitudinal direction of the cantilever arm and are supplemented by at least one additional axis supported transversely with respect to said axes. This compensates for a migration of the articulation point in each direction.
