Abstract

An apparatus for placing foundation devices and/or pipes and/or augers in the ground, as an attachment to be attached to the boom of a construction vehicle, including a mounting hinged to a coupling point of the boom, and a drive head, which is rigidly connected to the mounting and configured as a rotational driving and/or drilling and/or impact drilling and/or pile-driving drive and to which the foundation device/pipe/auger for placement in the ground can be coupled. The coupling point can be displaced with respect to the drive head in at least one first direction which is transverse to the longitudinal axis of the foundation device/pipe/auger, and optionally in a second direction, which is transverse to the first direction. The mounting can be a universal joint in which a first joint axis extends so that a first and a second joint part can be displaced thereon, relative to each other, in the first direction, so as to displace the coupling point. A second joint axis may extend so that the second and a third joint part can be displaced thereon, relative to each other, in the second direction.
